DIY: Volkswagen MKIV HVAC Light Bulb Replacement
HTML-код
- Опубликовано: 3 окт 2024
- Video tutorial on how to replace the light bulb located in the heater, ventilation, and air conditioning control switches/panel in a VW MK4 Golf, Jetta, Bora, or Beetle. There is only one bulb that lights up the whole panel and there is no need to remove the panel for replacement. This particular tutorial was done on a 2004 Volkswagen Golf TDI.

10 years later and you’re still helping people. Thank you for uploading. I couldn’t get my bulb out with pliers but I used a vacuum hose connector and it came right out.
Yep, Dec 1, 2022, here I am too.
Here in 2023!
11 years later going strong
Same here.
Two years in the dark... until I saw this video a few days ago. Ordered the bulb online and it arrived today and in a couple of minutes I had lights again!!!
My bulb was pretty tight, but the needle nosed pliers with a bit of tape was a great idea.
Thanks!!! :)
Thank you!
The bulb type replacement is 2721.
I found this video by accident while trying to find some other DIY Jetta tips. Followed the directions and now I can see the dials for the first time in almost 5 years. In fact, the whole process only took under 2 minutes was faster than the time it took the parts counter at the dealership to find the bulb! Thanks so much for this video.
This made it VERY clear that some one was trying to take advantage of me not knowing what it took to fix. Thank you.
Said that the whole dash must be removed to do it.
was just about to strip the bottom half of the dash out. Saved me half a day. nice one.!
Lol, by far the easiest bulb replacement I have ever experienced.
Thank you! It’s nice to have lights for the climate control again!!!
Awesome to hear, happy to help!
Excellent DIY! after months of driving at night without any HVAC control lights, I followed this DIY and replaced the bulb on my 2005 Jetta in only 3 minutes. The bulb on my MKIV Jetta was a 12v 1.2 watt. Autozone has the bulb (part # 2721LL)
Thank you !!!
Great video. Needed to know for sure that the fan knob was removed just by pulling.
Not to be critical, but as a suggestion, avoid touching small clear light bulbs (flashlight, headlight, halogen work light, this bulb) with your hands/fingers. The oil from your hands will absorb heat from the filament and can cause the glass to warp and crack.
Thank you for providing the video. Have fun with your Golf!
This worked for me. I was a bit worried because my Golf is now almost 20 years old and everything (esp. plastic etc) is close to breaking. I wasn't able to pull für bulb out first so i used doublesided tape on my pliers to give it some more grip. After that it came out rather easy. A hint from my exerience is to wiggle the "knob" at the start a bit, that way you don't need that much force to get it out.
This way it is much easier than the methode where you need to remove the whole control panel.
Good luck you guys.
Thank you for the Video (7 years Later xD). Very very helpful.
Internet needs tutorial videos like this. No bullshit intros "okay everybody subscribe and hit the like button". Thanks. Now I can fix my light in mk4 golf.
Thank you. This was ideal- well spoken, clear, great camera angles.Saved me $100 at the dealership. Greatly appreciated.
Thx for the tip, for those who might want to switch to LED, the bulb is 12v @ 1.2w with a T5 wedge type connector. I found a pack of blue LED bulbs on Amzn to match the instrument cluster for the same price as a #2721 replacement bulb.
I got to mentioned that this light not working has bugged me. I saw your video and got the light working in no time. Honestly the bulb came out of the socket and just needed to be pushed back into place. Thanks.....
Been wondering how to do this for over 7 years, lol. Wish I'd checked on here before now. Job done. Thank you so much.
thank you for the information , its great to see people doing a good job and showing others how to do this kind of job best wishes to you
It's just the one bulb that lights up the whole hvac control panel. As for the red ring around the 12 volt input, I've never had it apparent personally, but I would imagine there is a bulb also used in that unit too.
6 years and now i changed it :)
Thank you!
Great video! I started taking everything apart and was getting frustrated. Got smart and found this video. I would have never found that bulb. Thanks!
fantastic! I had begun to tear apart my dashboard so this has saved me alot of hassle and aggro. Neil.
Excellent to hear Neil and thank you for the feedback. Don't forget to subscribe!
It's just a standard incandescent bulb... It's not like the halogen style bulbs found in your headlights which will burn out from the oil on your skin if it gets in contact with the glass.
@Corkoth55 The only way I can think of removing the left over bulb is taking a very small screw driver and slowly pry along side the bulb base and work it out. Or if the wire filament is still there, then you might be able to grab onto it with pliers and pull it out.
I actually had spares kicking around, but you should be able to buy this from a local auto parts store such as APC, Car Quest, Parts Source, etc. An electronics supply should also carry this bulb.
I've never had any issues myself, but I have heard of others having that problem. So that could be the possible cause unless there is an internal electronic problem with the hvac controls themselves rather than the switch or there is a short in the wiring.
This was actually the very first vehicle I've ever experienced with it having the bulb located under the knob. I would imagine that Toyota has it located directly behind the hvac panel, so you will most likely have to remove the panel itself to gain access to the bulb.
This video really helps!! I have a Golf MK4 and I had seen a same problem on a 03 Jetta that the back light was out of work. Have just tried on my Golf today and it works perfect! Gonna switch the bulb on the Jetta later XD. Thanks a lot to this video!~
For a second I thought I was stronger than you because I can remove the knob by hand, then I remembered that my Mexico made Jetta(Bora) wasn't as tight and well built as the European Golf, thanks for the help :)
Lol, the hvac unit is probably made in the same plant and then shipped out to the assembly plants. Glad to help out!
I managed to get it off without pliers mines a Euro car
Thanks a lot man!!! It's very easy to do it, I was thinking to pay a lot of money for an easy to do job!!!
A piece of small rubber tubing that fits tightly over the bulb does the trick. Cut a small piece, stick it on the bulb, then use needle nose pliers to grab the hose enclosed bulb. Use a longer piece with the bulb stuck in the end to insert the bulb. After the bulb is in, twist the hose to remove the hose.
Great tip. Also the entire buttons can be pried revealing the entire bulb. Could not pull it out with pliers (no glove)
Thank you , i drive since 3 months without light
Lol i have driven 1.5 years without and just realised that it is supposed to be illuminated
I found that duct tape was better at gripping the knob and bulb thanks for the vid
thank u so much for the detailed video and for teling us the numbers and the orientation of the bulb
No problem, happy to help :)
Thank you very much. It cost about €4,00 for 10-pack of the light bulbs.
i did this on a 02 lupo gti its the same. very helpful. thanks bud
It is a light bulb, which is accessed by removing the ashtray, then removing the screw or two under where the ashtray was. Then the front of the assembly will push down and forward toward the engine about an inch and then you can remove it. At this point you can access the plug for the power point and unplug it. The light bulb is in a little plastic holder on the side of the power point. Insallation is reverse of removal. Good Luck!
You can find them in your local auto parts storr, i picked them at autozone. Its either a 2721 buld or a 2723 bulb.
Yes it is.
FYI usually you don't want to touch light bulbs otherwise great video and pics, thanks!
very thanks !!!
greetings from Poland !
Glad to help out and thank you for the feedback :)
Done this with my VW Beetle, bulb working but fan not.... Just to mention if you extract the dial when it is on 2 rather than 0 it wont spring the fan contact out of place and the fan won't work. A lesson learnt the hard way by myself which led to the whole unit being taken apart and the contact being put back in the right place.
Been driving without it for like 5 yrs. why didn’t I try researching this sooner. Damn
Thank you so much! This was extremely helpful!
Thank you for the feedback :)
Thanks man. Finally my hvac control panel lights again.
p.s. It's the same on my Golf mk4 1998
test before you put the knob back on
Great video. The light on my 2000 Mk4 was busted when I acquired it so I didn't know it could even be turned on. I assume it would work the same way as this vehicle as both are Mk4 vehicles.
Thank you, don't forget to subscribe :)
Thank you so much for posting this!! It's been bugging me for a while not having this light work. :-)
Nice monster mats ! So now I know they fit a mk4
Thank you! I bought these from the dealer, they were specific for the car.
i love mine. the MK4 mats are different than the MK5 and newer. the connector is different so make sure u order teh right ones
Possibly you could. I know there are LED bulbs available, I had smaller style bulbs exactly like this for my halo headlights on a BMW and I did purchase LED bulbs which could be bought in a variety of colors from vleds.com.
I need to do this now. Thanks!!!
vwG mk 4 forever ! thanks for the video !!!
Happy to help :)
Excellent Video - I also need help with Speedometer/Rev Counter dash lights - After I turn off the lights, a light blue glow remains - Even after everything is turned off and Key removed…?
Could you also tell me where the Speedometer Sensor in located…?
Nice and easy! Spare much time.Thanks
Glad to help out and thank you!
Thank you for the help ...I'll replace mine tomorrow ....
Thanks man just did it on my MK4 Golf thanks to your vid really helpful :)
Отлично все сделал. Молодец!
Thank you very much, very helpful. Although i could pull out the central knob with my fingers only. Golf IV 2001.
Beautiful - just what I needed. Thanks!
Happy to help :)
You can use one of the vaccum hozes and it can pull it off easily
Great tip, thanks for sharing!
Helpful video, just some questions. Is the center switch the only bulb for the whole hvac controls? Or does each switch have its own individual bulb? All of my hvac controls won't turn on anymore. And Do you know how to get the red ring around the 12volt input to light up again? Could it a fuse or another bulb? thanks-
Very well spoken. Great DIY
Going to try this in a 00 bora. I'm sure it's the same.
Thanks.
Just to clarify, are you saying that the knob should be extracted when it is in position 2? I have the same problem with my beetle and don't want to mess anything up. Thanks
I need to do this and you helped me alot thanks.
+justin beamon Excellent to hear and thank you!
Many thanks for posting. Made the job so easy! Thx
Nice video. I needed it!
YES, THAT IS WHAT I NEED IT, THANKS
man ur interior is so damn clean
Thank you! Sadly it wasn't like that when I purchased the car, here's what it originally looked like ruclips.net/video/dNmgZ6yQn10/видео.html
Thank you very much ;-)
In highly appreciate this tutorial
Now my wife's car is fully operational ^_^
So helpful.
Have you heard of the a/c not working because of this unit?
Possibly yes.
@4DIYers yeeah... i tried (tiny little piece of filament there) to grab it and the pliers ever with tape were getting no grip... that's what the problem was b4 it broke.. (yes, with tape on them) the pliers just kept sliding off the bulb.. electrical tape isn't very grippy, it's too smooth. but i see it worked perfectly for you :(
Hi 4Diyers!
I have an identical HVAC control panel in my Skoda Octavia Mk1. Last weekend I noticed, that non of the lights were working. The question is: Is there is one bulb for all three knobs? if not, there must be some other problem.
Thanks for your answer.
Yep, it is 1 bulb for all three knobs.
Thank you! :) I hope it's the same in my VW passat, the controls looks the same, so fingers crossed.
Extremely helpful thanks 😉👍
+holly33tube Excellent to hear and thank you!
Great Video....I think it will work on my 2003 GTI....we have the same knobs.
Thank you for this awasome video.
No problem, happy to help :)
very helpful and well explained video, thank you
The bulb for the 12V (I assume you mean the one by the ashtray) is not too bad, but not as simple as the HVAC bulb. Not enough characters here to write instructions; I suggest searching in a forum such as VW Vortex, where somebody has surely asked the question before. :)
Great video!!
Thank you!
Thanks
I'm driving with this this problem for almost 2 or even 3 years now. First it was flickering then went dark and I'm driving mostly at night time and it is really non-convenient but I thought it was bad connection somewhere
i bought an MK4 jetta a few months ago and i just have a question for you, Could it be possible that the woman who owned it before me replaced this light and did not put the HVAC switch in the off postition when she put it back because my air is always on?
Thank you !! It really helped !
There's no need for needle nose pliers. If you take out all the knobs and face you can use a pick or small flat head screwdriver.. at the corners. There's like small clips. You "unclip those" and the whole thing comes apart. Them you can just use your fingers to pull the bulb. Use a clean rag or paper towel if you don't wanna touch the bulb. I just did it myself.
Thanks a lot very helpfull
Glad it helped and thank you :)
Hi, thanks for the help, now I now how to fix my nroken lightbulb on my VW Bora - But I have a question, theres no light in my ashtray / lighter, how do I fix tihis?

Mine went out last night. I'm going to replace it when autozone opens I hope to find the lightbulb
@cristian7477 Yep, it's just the one bulb.

Thank you for the feedback!
I've a 2001 Bora which shares a lot with the Mk 4 Golf. How do I replace the bulbs in the rear interior lights (lights are above the doors) please?
Very helpful video. Thank you.
Thank you!
Great video I was wondering why my controls was not glowing at night. I am restoring my MK4 from a kid, the radio is not installed and lighter is not working. The a/c and circulation buttons light up but not the 3 climate controls. Is it still possible to be the bulb behind the fan speed control? Thanks for the help and great DIY videos..!
Thank you. Only one bulb lights up all three rotary switches. Don't forget to subscribe!
is there only 1 that bulb lighting the 3 dials or is there a bulb behind each 1?
N.B. Check bulb operation before reinstalling control knob.
Thank you very much you saved me some cash
helpfull for many people!!
