Re: '96 GC Air Conditioning woes
Ok, I have read in a few places that the blend air door is defective
which effectively stops the AC from working because it won't go from
'heat' mode to AC mode under the dash.
I believe it is also vacuum operated and the vacuum line can become
disconnected. Hear any strange hisses or have any other vacuum related
things that work slowly?
I am wondering if this is all that is wrong?
If you turn on the AC and things under the hood appear to work, than
maybe it's just that door?

Re: '96 GC Air Conditioning woes
Billy Ray,
I figure the leak just started in the past year, and then drained down the
system, to the point that it would not cool. That is my experience with
leaks anyway. It is unrealistic in the extreme, to expect that a recharge
can is going to give another ten years of service. Otoh, they cost a lot
less than $1,700.00!

Re: '96 GC Air Conditioning woes
Billy Ray,
I figure the leak just started in the past year, and then drained down the
system, to the point that it would not cool. That is my experience with
leaks anyway. It is unrealistic in the extreme, to expect that a recharge
can is going to give another ten years of service. Otoh, they cost a lot
less than $1,700.00!

Re: '96 GC Air Conditioning woes
That actually makes it look easy. What the picture doesn't show, is how
many connections and how many fasteners you have to remove, to get to that
point. I'll bet, it's a few.
