1999 Chev Astro AC problems.

Postby jerryjerry05 » Thu May 21, 2020 5:35 am

Hi, first post.
I'm a fairly good mechanic and can usually figure out the problem.
BUT!!
I have a 1999 Chev Astro van.
I can't seem to get power to the ac
The fuses are all ok.
The connections all ok.

I try to jumper power to the fan/clutch, nope. The lead gets smokin hot?
I try to bypass the high pressure switch, nope. The lead gets smokin hot?

Some suggestions???
I've taken the dash apart and can't find any relays like I had in my Suburban??
The controls have power but nothing goes to the unit.

THANKS!!

If you did those tests as I think you did, might be a grounding in the AC clutch.

I should have added the compressor and clutch is new.
It had the problem before the compressor was changed.

I have a complete of service manuals for a 1998 Astro van. I believe they are the same for a 1999.
I will sell them for $30.00 plus $40.00 shipping. They are complete and heavy
