About two years ago the air conditioning on my 1999 Jimmy (4.3L V6)
was working, but wasn't overly cold. I had it recharged at my local
GM dealer which got it working properly again. According to my
paperwork, after putting the dye in the system they weren't able to
locate any major leaks. They also had me bring the vehicle back two
weeks later to check again for leaks, and they didn't see anything
"obvious". (such a fun word they used...)
This year the problem seems to have returned. The temperature of the
air is cool at best, but it still seems to be taking the moisture out.
When I have the AC turned on and check under the hood, the compressor
is cycling on and off / making noise like it always has, so I'll
assume that much is working. (I fix computers, not cars) Also, if it
makes a difference, the heat is working fine...
I have no plans of trying to fix this myself, not that I could since I
don't have any of the proper equipment. What I'm trying to figure out
is if it's worth paying the dealer to figure out, or fix, whatever the
problem is. I don't want to end up spending thousands of dollars to
replace parts if it's going to end up being a waste of time and money.
The time I can justify, it's the money I'd rather not part with. :)
