Hey Guy's, I got so much good advice the last time I had a problem with my
car I decided this is the best place to get help with my A/C. It's a 99
camero, SS with the LS1 engine. When I turn the A/C switch to cool the fan
comes on, the compressor engages and stays engaged. Air blows through the
vents. The problem is it will not cool. I tried switching to defrost just
to see if the vents were working. All seems to be fine. Any ideas on what
the problem could be? I was hoping it would be something simple, but the
fact that the compressor stay's engaged tells me it's not low on freon. BTW
It uses the newer 134A freon.
If it stays engaged that means it's low on freon. It's supposed to cut out periodically. You need it filled up.
Strange I thiught that if it was low on freon the low pressure switch would
kick out the compressor.
Thanks, I got an A/C tech who is gonna take a look.
Nope, it's trying to compress it, but there's nothing to compress. Just think of an air compressor, if there's no air, it'll run forever, it needs something to compress to get the PSI/KPa up to make it cut out.
check pressure put dye to see where the leak is .its amazing the japanese still work 15 years later :ford gm 6 years is all she wrote....parts from the cheapest bidder..
hmmm that sounds familiar, apollo 13?
Ummm... it doesn't have to leak to run out of freon, every vehicle in the
world needs to be recharged eventually. You don't even know how to fill a
car with freon, so you think he's going to know how? And did you not know
you need a UV light, tinted safety glasses, dye, freon, and an A/C filling
station to do what you just recommended.
Think then post.
Unless you live in the U.S. then good luck getting ahold of freon here... illegal to sell anything but r134.
have a a/c guy look at it, there's no way you can really know what's up until you put gauges on it. btw, the low pressure switch should cut the compressor out if it is low on charge. and a/c systems are sealed systems, unless there is a leak, they should never have to be recharged. (but almost all of them leak, eventually)
