The leak on all evaporator is on the aluminium core not on the expansion valve. The humidity produced by the cooling cycle produces fungus. This fungus eats the aluminium and produces microscopic holes where the R134a leaks. The life expectancy of the evaporator depends on the thickness of the aluminium core. Like most thinks in the car industry all original evaporators have built in planned obsolescence. In this case I don't think the leak has to do with location behind the rear tire since the evaporator core is inside protected by the plastic housing.

Hey great video. I am hoping to block the rear ac line off completely, but I am concerned about what happens to the compressor oil after I do so. Would the compressor oil be backing up in the line with this method? I was told that the proper approach would be to block the line off up front.
I want to insure that the compressor continues to get oil, and I am not sure where or how to block the line up front so that it can still circulate. I really need to get this fixed asap. Any help or suggestions would be greatly appreciated.

you can buy a cap kit for around 70 online and under the passenger side door there are two unions that can be unscrewed one for high one for low pressure and the kit just screws right onto those to block off the rear ac. no cutting of lines required. im no mechanic and was able to do it on my wife's 2011 dodge grand caravan in my driveway in less than an hour. there are vids on youtube that show this as well.

My 2015 Ford Explorer has the same issue I believe. all because living up in the north east eats away these rear lines that arent insulated enough apparently. Im hoping I can pull off a fix like this because to reline the entire system I was quoted at over 2k.

Isnt there an aluminum block type used to bypass this under the hood. Allowing fan just no evap flow. I have said done to mine from previous owner when I bought my used suv. Assuming theres a leak in the back

Im sure somebody already said it. but hotrodguys sells excellent block offs. I have used a ton of them on Chrysler minivans. 60-70 per kit if I recall. no compression fittings.

I think you did excellent work on other car, but this one seems wrong to me. you should block from very front, instead of read, as TC most leak happenned on the pipes in the middle.

Question, if one of those lines got a split in it or a small crack, can you cut at that point and apply a high temperature rubber hose and clamp it? Great video!
