Thank you good Sir. The AC compressor clutch in my wife's vehicle decided to no longer engage on (ironically) the hottest day of the year thus far. I watched videos on jumping the connections in the fuse box which looked too risky for me. Diagnosing the state of the relay is the proper way to go. My relay proved to be in an open state. I drove to my local Subaru dealer this morning and purchased a new relay for $8. Got home, popped it in, started the car, and voila! AC is working again. Thanks again.
Was able to check all my relays . I have a 12 volt power controller that I used for voltage then used my meter. Great video. All my relays work. Thank you so much for this wonderful video
If you have a Toyota consider keeping a spare A/C relay in your car, it can save time and aggravation when your A/C suddenly fails in hot weather. It doesn't always fix Toyota A/C but it is a good shot when it abruptly fails.
I would rather buy the tool you hook up to the negative battery terminal ? And it has slots to insert the relay and it will tell you if it's good or bad .
Thankyou very much Sir..I have the same problem with my Honda jazz..So I am looking where is the relay ...Can I try the same process like you.Merci..From France..
my day time running lights strobe on and off/ left and right like an ambulance. I installed 4 LED lights and no problem for over a year. Also installed anti flicker units yesterday and it doesn't change. I even pulled the fuse to the DTR lights.. no change..but Something changed in a years time but I don't know. What's my the problem here? Headlights work normally when turned on ..hi and low beam. I looked for an answer/ similar problem on line and didn't find anything.
question? I used a test light on the ports #86 for the starter relay. I used the clip on the positive terminal to see if #86 lights up and it did. it shouldn't light up correct???
Power Probe can be use here? At least you dont have to drag a 12 volt lead battery( that motion, removing the battery from an ackward deep angle is responsible for many a mechanics' damaged back discs ). But i am glad for test procedure.
Hi sir..i owned honda civic 1996..my car A/C clutch sometimes engage sometimes not when in stop situation.(moving).It was suddenly happens.. clutch clicking.tqvm
Got a 2004 Toyota Corolla doing an engine overhaul, engine is almost ready to go back in but then I also had hot air las time car ran, so i wen off without limit and bought all AC tools and parts required to do a complete overhaul which it should be a little bit less expensive than a $1700.00 shops charge for doing this kind of work; a mechanic suggested to me before I started taking the system apart that take it to a pro and get a diagnostic but then there it goes trust; there is a reason why I am doing this painfully slow overhaul, then i came upon this video; well i think I may have found the issue in my case; my relay has continuity between the silver leads, one is marked on top with a black dot, I am assuming meaning negative? in any case polarity should not affect continuity, but when I test the brass leads after applying power from the battery there is only 0.1 and 0.3 ohms reading; using a Fluke 107 meter which is the one I use for work (Electro-mechanical field engineering, similar to mechanic without so much grease and grime) so then I tested the compressor and clutch engages. Car engine is off the bay still but AC components are sealed, I have only disconnected the power steering pump and was thinking to get the engine back in with all the parts attached and serpentine belt as well, as it turns out, seems the culprit is that relay (system reads 65PSI in low port with 100F outside temp, did not hook the hi port) so it may be low on freon as well but with the compressor engaging i do not think i will recover the freon and disconnected it, unless someone would suggest to do a maintenance of the system given having the parts and tools to do so, my idea came as I thought it would be easier to work on the AC components with the engine off the bay than with the engine in but as it turns out there is really not much difference; mind you I still have to see if the car will crank and start once i drop the engine back in; i worked on this car taking my sweetest time over the course of 3 years, everything in the engine bay major have been replaced or re-done; the original issue was failed gasket due to overheating because neglecting oil and coolant, twice!! the first time we went with a "mechanic" only to happen a second time in less than 2 years (it was not because of me the issues, but I was blamed all the same!) so here I am trying to complete this car; this video helped a lot. Thanks for it. I subscribed!
VERY GOOD DEMO.Thank you.But it is ok using replacement relay with no markings just same pin orientation??My original but defective has its part number and cant find with the same PN although have same pin, are those safe to use? thank you very much
Great Question. Best way to find your positive is unplug the relay: insert a 12v test light on one of the open slots of the relay plug. Whichever the light comes on that indicates the hot 🔥side then correspond that with the relay
Hey: Does anyone have an idea why my axillaries are not working? I recharged a recently new battery (96w)over night and placed it back in the van(Peugeot Partner DW8 2004), but now my horn/Digi clock/courtesy light/indicators/high beam and wash/wipers don't work! When I switch on my ignition my side lights come on and when I switch the engine on my main beam lights come on with the light switch off! So my lights are staying on all the time as long as the ignition switch is on and I cannot switch them off at the switch. When I switch the engine off and remove the keys the lights go off. The remote locking/alarm system also works. I have checked all the small fuses and none of them have blown. I haven't checked any relays as coming from this video yet. This is so strange and all I did was recharge my battery and put it back in again. Could it be an open circuit caused by possible power surge on the relay that controls them damaging it, or could it be something else? Any help is appreciated..
Well all I can say is dont try this at home. ElectroBoom ruclips.net/video/ylGoHrVKGI0/видео.html He is an expert. But check out his other informative videos.
I'd try popping off the cover and burnish the contacts and would hope they were not burnt to bad :-) Maybe a tad of arm bending too. Getting a new one is always better though.
Good in principle but shouldnt be touching the probes with your fingers as a reading will be inaccurate. Very bad practice too as one day it may be high voltage being measured.
Its How 2 take out a relay instead!! stuck won't budge unless I pull out the whole housing , breaking what holds it all together instead of just the fuse, a econoline e250 2001 is a bitch!!!!
Putting your index fingers on each test probe metal tips will give you an incorrect resistance reading! reading. Doing this provides a parallel path through your body: Kirchoff and Ohms Laws, blah, blah, blah.
You should not touch the metal probes with your fingers when taking your readings. Touching the probes gives continuity and ohm readings to the probes through your body Try that with a/c power. U wont do it again.

My car was a problem,I tested all raley and got one of them not walking and replaced it,thank you so much I love you
I love your style of making videos. Simple, yet very thoroughly explained. Thank you very much for this!
Was able to check all my relays . I have a 12 volt power controller that I used for voltage then used my meter. Great video. All my relays work. Thank you so much for this wonderful video
Thank you so much for the detailed procedure. Was able to determine the relay was bad. $12 later and AC is working again.
Have always wanted to know how to properly test a relay, and now I do. Thank you sir for yet another simple yet informative how-to video!
Yes I liked your demo of how to test in the garage and also at the road side brilliant demo Sir. Great for the newbie.
Thank you so much for the information. This is the best information I have found on RUclips.
Clear, visible, informative and to the point. Thank you.
Your videos are spot on and straight to the point.

What a great idea ..
Well and straight explanation,i like it,thank you very much.For good video tortural..
Love this video. Needed a simple explanation
Works?, With out guys like you on the internet we wouldn't get anything Done to are car. Keep up the good videos 👍
Thanks for sharing this video , great information explained.
Good demonstration, thanks for sharing. 👍🏻👍🏻👍🏻
You likely also have an audible (beeping) continuity setting on your multimeter. That might be more suitable when just confirming open and closed.
Thank you for your informative and excellent demonstrations .
Excellent explanation
Thank you for sharing this very informative video.
I would rather buy the tool you hook up to the negative battery terminal ? And it has slots to insert the relay and it will tell you if it's good or bad .
Good video chap 👍
Very helpful my friend
Thankyou very much Sir..I have the same problem with my Honda jazz..So I am looking where is the relay ...Can I try the same process like you.Merci..From France..
Great video !!!
Cool thanks now I know how to I have one to test
Great advice again.
Love your videos bro!

Thanks. Well explained!
well explanned thanks
Sir how many thumbs you want from me thanks
A/C button light blinks 3 times when the clutch relay goes out in my Toyota.
Hi, I have haice Toyota van diesel 1994, which relay involved in glow plugs please? Thanks
Great stuff, thank you.
The A/C works but the clutch kicks in with the fan and the both turns off together is that how it works?
How about relays with 5 pins?
Informative but needed a closer look while connecting the relay with the battery, otherwise it remains a bit unclear.
Gracias amigo muy buena manera de enseñar, muy buenos videos
Excellent, thanks.
Your channel is aimed more towards making Toyota mechanics better.some applies for DIY mechanics but not for professionals...correct?
thank you vick help
When i test my relays after I apply the 12v the multimeter reads 0 numbers jump around then reads 0 is the relay good?
Super
VERY GOOD DEMO.Thank you.But it is ok using replacement relay with no markings just same pin orientation??My original but defective has its part number and cant find with the same PN although have same pin, are those safe to use? thank you very much
always wondered.... when testing a relay outside of a vehicle, how do you know which side is positive and negative? (or does it not mattter?)
Great Question. Best way to find your positive is unplug the relay: insert a 12v test light on one of the open slots of the relay plug. Whichever the light comes on that indicates the hot 🔥side then correspond that with the relay
Thank you for advice.
Thank u but, I wish video would b closer to the demonstration. Other wise awsome
Wow, thank you
Very good , thanks.

Thanks Mr. Toyota Maintenance...…… I've got one of those damned multi-meters, but don't fully understand how to use them ! Thanks!
Well all I can say is dont try this at home.

Do you have email or other way to send you pictures of relay issue.
Thank 👍
👍thanks
You should not touch meter lead probes with your bare hands as skin has resistance on its own.
Good in principle but shouldnt be touching the probes with your fingers as a reading will be inaccurate. Very bad practice too as one day it may be high voltage being measured.
Love it
Thank you for un-confusing me 🤓
Should not applied power when checking ohms, should use test light instead of multimeter.
You should keep your fingers off the tips of your leads to get an accurate reading
Thankssss
Camera is too far away during the second test.
Engine off while driving, it will not start immediately until you wait for about 15minutes
So.
You could TEST IT,,by stopping over and BLOWING THE HORN,To TEST IT.???.
My relays goes up on numbers then it goes to 0000
Voyant. Precha uffage. Reste. Allumer
Hard to understand😢
Its How 2 take out a relay instead!! stuck won't budge unless I pull out the whole housing , breaking what holds it all together instead of just the fuse, a econoline e250 2001 is a bitch!!!!
Bad lighting
,!
My relays don’t look like yes didn’t help 🤷🏼♂️
