This 2011 Dodge Ram 1500 had a serious Evaporator core leak so on today's video we tackle the dash removal and get the HVAC box out to swap the Evap core. #DODGE #RAM #AC
It's about a 6-8 hour job for someone mechanically inclined. If this is your first time doing any major auto then this will definitely be a weekend job
For the DIYers watching this, as many already commented, the truck doesn't need to be stripped out this much. Here's the short of how to proceed and not damage in order to remove the box to replace either the heater core, door actuators, or the condenser: 1. Roll front passenger window down, and move seats all the way rearward and then disconnect battery. 2. Evacuate refrigerant and drain coolant or clamp off the heater hoses ahead of the firewall. 3. Place a fender protector or moving blanket through the passenger window to drape over door panel - this will make sure the protruding studs from the box don't scrape it up. 4. Remove center console from truck. 5. Remove the A-pillar trims, trim on either end of dash, kicks, and under the wheel. 6. Drop the column - no need to remove. Wrap the wheel and column in a moving blanket, towel or similar to protect. Cover seats with moving blanket or towels now. 7. Remove the 3 bolts at either end of dash, 2 bolts at the top against windshield and 2 down where the console was. Disconnect the harnesses on the passenger side 8. Get a helping hand and lift and tilt the dash back and bring the passenger side further back. Hold it up and back with a strap hooked to the the rear clothes hook, driver's headrest or such. 9. You can now get to the box to remove fasteners and wire connectors, and don't forget the fasteners on the engine side of the firewall. 10. Pull it out, and regardless if replacing the heater core or condenser, check the other one and clean thoroughly. Be sure to check brand new and reused parts for leaks before reassembling! Simple vacuum or pressure test will save your sanity! Also, I honestly replace both while in there and also the actuator!It's an extra $150 in parts, but a lot of savings in the long run... DO inspect all of the doors. If you find any broken, stop and order aftermarket repair kit! This is also when you want to add the cabin air filter to keep the condenser clean if, like the truck in this video, it's not there from the factory. Do not buy the "kit" from the internet as they make a ridiculous profit. You can buy the door from the Mopar parts counter and the filter from anywhere. I like Wix personally. 11. When you reinstall, make absolutely certain to replace the anti-rattle padding as the factory had and make sure the seals for the firewall pentrations are intact! If you don't, it will aggravate you if DIYing or cause you to redo the project if a pro! 12. Reassemble in reverse order, vacuum and recharge the air conditioner, and reconnect the heater lines and add coolant. Burping the core of air takes some work because of where it sits in the system.
@Kendall Engman No, the HVAC box in which the heater core and AC condenser are mounted contains several doors that open and close to switch between heating and cooling, directing air flow to defroster, floor, etc, and those doors are controlled by electronic actuators, which is a fancy name for a small motor assembly. They are prone to wearing out, and sometimes the doors in the box break. Best time to check and replace is when the box is out. One of the actuators mounts to the front of the box, meaning it is right against the firewall when the box is in place. So it can only be replaced when out of the truck, which is why I just replace when the box is out with a new one as preemptive maintenance.
@Kendall Engman At a minimum, inspect the doors. 3rd Gen RAMs have the problem most frequently, and 4th Gens the older they are. Yes, I have used that company, and their replacements are high quality and perfect fits. As for the actuators, at least the one that's against the firewall and unserviceable otherwise. I generally use OE Mopar replacements.
By far the best evap video I have ever seen. After watching the video, pulled the dash out in 2hrs.. So easy when you don't waste time removing parts that don't need to come apart. PLEASE make more videos anytime you do another evap... Awesome job. I'm in a small shop and time is valuable when you only have a couple bays. THANKS
Awesome video.. FYI if you are just doing the evaporator you can lay the dash over to the driver side and you do not have to unhook the harness under the carpet or take the steering column completely out. That way takes about 40 minutes with power tools to get to the hvac box 👊🏼
For book time 7 hours. I’m on day two and I could have save so much time by dropping the steering column ALOT sooner than I did luckily I had a small box under the cup holder so I don’t have to remove the seat 🤣 thank you for posting this
Guys i did not remove the wire harness under the carpet, i just rest the dashboard on the seats area and there was enough room to remove the heater box,i also replaced the resistor
i like how he just tells you what to take off and shows a sped up video of the outside of the truck, while all of the work is done inside of it and they dont show any of it
No need to remove seats or column. Just drop column, remove the main dash bolts (3 on either sides, 2 up top and 2 down center) then drop the column to the ground. Pull the dash out and hang it with a strap, disconnect some electrical along the sides as need be to pull it back enough to get acces to hvac box. Got it done in book time
@@vern2k653 yes I realize you can do it without removing the seat and dash completely but I prefer to do it this way because it gives much more room to work and less risk of breaking or damaging anything
@@ChrisVaughnTech yes there is a bit more risk but I can’t fathom taking an extra day or 2 when book time only gives us 7 Hrs. I still haven’t broke any dashes doing it this way and it’s worked everytime
Good video that helped me, only thing missed is there are nuts on the firewall under the heater core line bracket and under the computer that have to be removed to get the hvac box out of the truck. The video only shows the three inside the cab being removed. Thanks for the video.
Great video. I wish this guy was in my city, I wouldn't worry so much about having this same issue fixed.i have the same center console. 2011 Long Horn Laramie.
What an absolutely ridiculous amount of work. After all these years, car makers can’t make an HVAC system that is accessible from passenger side? I own this model and year of truck ( no problems with ac yet) Seems like it would be easy for ram to make a hinged HVAC box. Just a thought
Tell me about it. I have the same year 3500 diesel and the ac just started blowing hot. This video made me sick to my stomach. I'm hoping mine is the compressor though, since I noticed it making a peculiar noise a few weeks ago. 70K miles on the truck that I bought new. I wonder what would cause the evaporator to leak in the first place. BTW, I read that they make an aftermarket filter for these that I had thought about getting, because of the musty smell when you turn it on. Mold and mildew from high humidity where I live. Know anything about that? Poor design to not have a changeable filter like my old Chevy had. And it was also very easy to access.
Literally all they would have to do is make the dash in two parts with a small crease down the middle or around the passenger side of stereo, if you could remove just the right dash, it would eliminate about 50% of this job and make it a lot easier IMHO, but cosmetically that crease people don't like to see it
This might be a long shot but I need some help. I have a 2011 Ram 1500. A/C stopped blowing cold 4 months ago, I did a recharge and all has been good for the past 4 months. Until one day it stopped blowing cold again. I tried putting the dye through it and looking for a leak with UV light and saw nothing. So I put another recharge through and the next day it wasn't blowing cold again. Hooked the gauge up and almost all the freon had leaked out. I'm not sure what to do next to try to diagnose it. Someone please help!!
Definitely don't have to remove seats, there should be enough play in remaining wires to just set dash on seat, you don't need that much room to remove the ac box
Replace everything in the dash while you have it out! Replace the heater core, the fan motor and the dampener motor. I would be FN pissed if one of those parts broke after paying for this repair. I think I'll cut my heater hoses under the hood and connect them.
On this particular one I did not since they were all functioning normally and the owner opted not to replace them. I do agree it's a good time to replace everything while you have the HVAC box out.
I use to do it like this. ❤️😊 good informative video. U can actually keep seats in and the steering column connected and dropped. Just pull the passenger side dash out enough to pull the box. It’s cool to see everything out tho.
How can you do this without taking out the seats and the leaving steering column connected? Also do you have to take out the entire center console? Do you know of a RUclips that shows how? Thank you!
@@christopherrobertson5492 I seen one one RUclips that you just drop the column in the floor. Rest the console on the Passenger side with the seat belt. Then you can remove the 4 bolts holding the System to the fire wall...3 on the inside. One behind the ECM....I got it out in 2 hours...As the only bitch was them heater hoses...I had to crawl on top on the engine to reach them...
I saw earlier in the video it has the centre console between the seats, any chance of a video on how to remove that, I cant for the life of me figure that part out.
I have excessive water draining from my 2009 Dodge 1500 with a HEMI. The a/c is cold, but the a/c water is draining really heavy and onto the frame rail below. Do you think my issues is also the evap core?
If your A/C is staying cold then your EVAP core should be fine. The evaporator will condensate a decent amount under normal operation so when it's very hot outside and the AC is on full blast you can expect to see a decent amount of dripping water from the drain.
@@ChrisVaughnTech beautiful reply. Don’t worry about condensation. Condensation is a good thing!! It means the system is drying the cabin air, get worried when there’s no condensation. Freezing lines is a no bueno. Still an easy fix. Freezing can be caused by a blockage, the blockage will be the point where system freezing stops. If you see the ice, replace where the ice stops. A manifold gauge may also reveal a low refrigerant charge. A low - low side charge can also cause a system to freeze. The low side pressure (to a point) is relative to core temperature. So if you have a 38 psi low side pressure, then expect the core to be only a degree or so different. Duct temp may be only a few degrees off of that as well depending on some other parameters like internal cabin temp out side temp etc. a 32 low side pressure indicates that a core could be freezing. In that case, I would check charge, then go for the evaporator temperature sensor to see if it is more than a few degrees difference. If you have a bad Evan core temp reading, it may never cycle the compressor off. That’s a no no and another cause for icing. Another cause for a core freezing could be a variable compressor not changing pump displacement. Seen that a few times to. But usually it causes the high side pressures to ram up high as well causing the pressure switch to disable the compressor.
Typically you do not for just a condenser swap.. but it's best to always check and see how much oil was removed when the system was discharged and add back that amount.
Thank you! I believe this is my problem on my 2011 ram. I have replaced the ac compressor, looked for leaking dye, refrigerant smell would occur in side of truck. Soooooo….maybe?? Lol
@@ChrisVaughnTech True but while you have that out, it makes monetary sense to swap heater core and expansion valve, and also the seals while you are in there, $500 more in parts but theoretically not more labor
Wow what an absolute horrifying job I will have on my hands.. If I send this to a mechanic I will pay over a grand easy to have my A/C fixed.. Tempted to just forget about it and ride with the windows down.
Not a good tutorial but I guess it'll get the job done. These only take 3hrs. Many unnecessary steps in this vid but like I said this vid is the scenic route.
So because you can do it faster this isn't a good tutorial?? Lol I explained exactly why the seat and console need to be removed and this is the procedure according to ALLDATA. If you can do the job in 3 hours then this video is clearly not intended for you lol
Very informative video. I will be doing this same project this week. How long did the job take?
It's about a 6-8 hour job for someone mechanically inclined. If this is your first time doing any major auto then this will definitely be a weekend job
If you take this to the shop, how much will this pain will be worth??
@@druhill9098 quoted me $1100
I was just quoted $1,295 to replace.
It costs $2295 here. Luckily it was covered under my warranty plan.

Did you add new compressor oil to replace the old that was in your old AC evaporator core?
that's part of the recharge process, depending on the refrigerant you use, it should have oil in it
they answer is yes dont forgot you vacummed the system out before removing lines
I'm surprised he didn't take out the engine 😂😂
