Dash air gone AGAIN - 1999 Adventurer P-40

[pegdiver]

our dash air has quit again! We are on our 3rd compressor - the first replaced at Winnebago, one replaced at the Chevy place and one replaced at a truck air conditioning place. The last one is still under warranty since it was replaced last fall. We were told last time that the o-rings were small and were replaced by bigger ones. Everything else has checked out OK every single time. We have replaced switches and fuses but that has never changed anything. Our pressure reading is OK, if anything a tad high.
Anybody have any ideas?

Sounds like you need to find a GOOD A/C technician rather than a buch of automotive parts changers...My 2 cents worth.

I have been in the industrial refrigeration field since 1970 and it is amazing at the number of parts changers out there that would like for you to believe they are technicians.

That is why we didn't go back to the authorized Chevy Workhorse dealer. At least the current guy did a dye test and found some leaks that were fixed. But then that dealer isn't a workhorse guy anymore now.

We are on our third compressor also and our coach is an 07 W20. What are the symptoms, if any, before compressor failure? Our first two started out with a clattering under power that gradually got louder before 'no-cool'. Our third compressor started doing the same thing a couple of months ago and we're pretty sure it's gonna go belly up pretty soon. How did you find out about the warranty time on your replaced unit? We'll be troubleshooting our Trek after the EAA Oshkosh Fly-in (WooHoo!) next week or so and will post the results here.

Nope - no noise - just stopped cooling. We had stopped to disconnect the car; DH got back in and no dash AC. Same with the other 2. The ac guy that did the work last fall told us about the garantee. We will check in with him when we get home.
EAA museum was great last year (just missed the fly-in)! Should have spent more time there but then we would never see anything new.

I was also told my ac was shot I think about 2 years ago. It was 2 vac lines that cost me about 10.00. I guess it wouldnt hurt to look at them.
