Delphi 7135 AC Compressor

We have a 2003 Winnebago Brave and we had the AC charged before leaving to go to Yuma (fall 2010). It worked when we got in the warmer temperatures but then quit cooling. We had it looked at during the winter and the Mechanic said he thought it was the compressor but we went with a sealant to see if it would block a possible leak. On our trip home this spring the temperatures were 100+ and we had no AC and really no where to go about getting it fixed. We are home now and after reading the Forum it sounds like there is a lot of problems with Delphi 7135 AC Compressors and finding a unit to replace it with. Our plans are to take the MH to a Radiator/AC mechanic and he will run a test on the unit to check out the problem. We are not sure if he finds it that he will be able to fix it for us. We love our motorhome but find all this very frustrating. If anyone has any easy solutions for us please let us know.

Take it to your AC/radiator repair guy first and see what he says. Got to find out what the problem really is before anyone can offer you a solution. Don't tell the AC guy that you think it is the compressor and let him see what he thinks without bias. It could be a simple leak from an oring or hose so there is not enough R134 in it or several other minor things. To find a replacement compressor you really need the number off the old compressor.

I have an '02 WH. I recently replaced the A/C compressor- The clutch bearing was howling. We got a brand new Delphi compressor through Car Quest.

I just bought another new compressor for my older S-10. Again, it was through Car Quest- $225.

Good luck,

I agree get a qualified HVAC mechanic to take a look for you
Yes that compressor is prone to failure they leak at the "O" ring holding the two sections together. I added greeen dye to the system and was easily able to see the green drip on top of the engine. New seals, oil and a new compressor cost $350 in parts and 1/2 day in my labor. Will also need to evac the system and properly test everything once completed.
Please do not toss your defective Converters / Inverters / etc. in the trash
