A/C issue
 

99 Accord EX with the V6 engine. 163,000 miles. Two weeks ago the A/C stopped cooling without warning. No compressor grinding or noises. I read the pressures on the low side and high side at idle and got 90 on the low side and 85 on the high side. Most likely cause? I jumped the compressor terminals at the relay and the clutch works. The relay is good. There is power to the relay. To make matters worse when I removed the gauge from the high side the freon leaked out in about 20 minutes. I could hear the hissing. Bad Schrader valve? I see a lot of $$$ to repair.

Me, I'd start with replacing the valve core on both the high and low side ports - and I'll break the rules and say leave the drier alone for now. Pull a vac on the system, remove the gauges once at the proper vac. Recheck the vac level ~20 minutes later.....what or how much did it drop?

All the freon leaked out. I just need to find the Schrader valves and the tool to replace them.

Problem w/ no compressor is likely electrical; AC relay, fuse, open clutch coil, or excess clutch gap (prevents coil field from closing clutch).

ackits.com is a good source for auto ac parts. Get a good quality AC Schrader valve to replace old. They are notorious to partially leak due to small debris under sealing surface.

good luck

also replace the dryer since you said it all leaked out.
