a/c problem

**cz28mdn** · 06-13-2008, 02:09 PM

well i'm new to this site, and i was wondering were i can find info about a/c. i have a 2000 trans am, and just recently i bottomed out and busted my lower ac line from compressor to canister. i replaced the hose, and used a vaccuum pump to drain the freon and used gauges to add two small cans of freon. i also replaced the orifice filter and the pressure sensor on top. the

the problem is that whenever i turn on the ac, the compressor won't kick in, after i installed the freon i turned the heater on first, and the compressor won't kick in at all. i'm not sure if the compressor is broken, but do you guys have any suggestions?

See if your getting any power to your compressor by checking the connector with a volt meter or test light when you turn the ac on and if your not check the ac relay and if thats good then its time to replace your compressor.

Complete evac and refill is 1.5 lbs - should be at least 95? psi on the gauge with compressor not running (depending on the ambient temp) to let the compressor kick on/charge. Is it holding static pressure or leaking out when trying to add?

well, i left the gauges on to see if the pressure dropped, but it was holding it pretty good with no leaks. know i don't remember what was the exact pressure, but i think i ended up using about two small cans. what i'm going to do is test the connector, get myself a new set of gauges and see how much pressure is in it.
