I have had to add freon almost every year. It usually takes the charge and the a/c works however this year it did not work. When adding the freon it just cycles thru and I have air con 4 about 5 minutes and then nothing. The compressor clicks on and off, there is no leak from anywhere. What do u think it is? Please help
A/C doesn't take charge and air conditioning does not work on 1997 Honda Accord

what are your gauge readings? you may have an evap core leak which you cannot see. will the system hold a vaccum? you may have a plugged expansion valve.
I replaced the high pressure valve and it just reads low charge. My mechanic has flushed the system no metal shavings or leaks. I'm waiting 2 c if a new compressor and a/c belt fixes it. I also have changed the fluids. I hope the compressor change ends my problem

Did the high pressure valve(switch?), or compressor make a difference? What are the PRESSURE readings from both high and low side when compressor 'clicking on and off'???
I am waiting 2 c if my new compressor and a/c belt works. My mechanic has replaced the high pressure valve and changed the oil. It has been flushed completly and there r no leaks or metel shavings. I am hoping the new compressor and a/c belt works. I have looked 4 a/c specialists and just found firestone, goodyear and some local shops I allready know about. I am stuck! I don't want 2 sell my car cause I have taken great care and always kept up with all repairs, fluids and what not. Sorry 4 babbling but i'm frustrated

Given the dealer a shot yet? One correct diagnosis may be less expensive than several cheaper guesses. Sorry , I don't mean that the way it probably reads , but I don't know how else to phrase it. Good luck. Please post the numbers if you are able---static line pressure , & high / low side pressures when running(whether or not clutch is engaging) Can the shop doing the work read live PGM-FI (Honda) data- NOT generic OBDII? If so , some of that info may be helpful.............evaporator freezing/thermistor in wrong position?
