A/C Compressor stays constantly running--is not cycling on and off. Only blows warm air.

I bought of can of R134a to recharge--it would only take a little in, but the gauge shows almost zero pressure on the low side.

I have no gauge on the high pressure side, but when i press the valve it lets out a lot of R134A.

So I have little pressure on the low side and high pressure on the high side, compressor not cycling off and only warm air.

Sounds like a clog in the system? Is there some filter?

92 Accord 190K miles. Thanks!

Your low side is vapor and your high side is liquid. Either the compressor or seals inside are worn out or you have a obstruction in the lines. I'm not familiar with Honda's and if they have a dryer in the system? If so, that could be the problem. It sounds more like to me that you have a bad compressor. I am a HVAC Tech BTW!
