1998 Honda Accord with 140K miles 4 cyl

Here is account of events
1. I noticed the A/C was not getting cold. Compressor is not activating
2. With a paper clip on the hi/low pressure switch, I can get the compressor to come on.
3. With engine off, Low port shows 25lbs with ambient temp at 56 degress
4. I turn on car and notice guage now shows zero..not good eh?
5. I add refrigerant with the car running and guage still shows zero
6. I check the Low port with car turned off, it was over filled so I pushed the valve to release some pressure.
7. AT 45 lbs and compressor working, A/C still not cold. The compressor clutch is definatley turning.

Help? And thank you in advanced for the education.

 

You have to vacume sys add dye and corect amount of freon and check both hi and low side pres. If your low on freon you got a leak someware

 

A 1998 Honda Accord does not use "freon". "freon" is not manufactured anymore since 1992. That car uses the refrigerant 134a.

 

bump...my concern is the low side psi is zero when car runs..not leaking R134a. thanks all
