I Overfilled My A/C, its Red on the gauge "May Have Mechanical Problem" - What To Do?

Ok so here is the story:

The A/C on my 2000 Honda Accord wasnt blowing out cold air anymore so on the way home from work I stopped and bought some refrigerant r-134a and put it in. The a/c was working fine after that but because I didnt buy a gauage I didnt know how much was in there. After a few days the a/c wasnt blowing cold air anymore so i went to buy more refrigerant but this time with a gauge to see how much was in there. When I put the gauge on the valve it went in the red zone which is like 65 psi, it was a little past the red zone and close to the yellow zone (Alert). Because there was such a high psi I decided not to put more in and returned the can of r-134a. What should I do because now the a/c doesnt work and I think I have too much refrigerant in there and its on the "Mechanical problems may be present" ... i dont hear the loud noise from the compressor and the hot to cold switch works fine, should I just press the needle on the valve to let some out? Any help would be greatly appreciated.

yes bleed some out

BUT WATCH OUT and keep your face away from that crap - 134 and OIL will come out.

get it back down to normal levels and see what happens then.


Is the compressor running when your AC is blowing? sounds like it stopped blowing cold air and you just assumed it was low on 134 and kept filling it and filling it. I think it stopped blowing cold air for another reason (maybe a pressure sensor)

ill let some out but i will check the compressor to see if the belt is turning when the a/c is turned on because if it isnt then that means the compressor is dead right?

the belt will always turn, you need to see if the clutch is engaging. it will usually do about a 50% duty cycle (a few seconds on, a few seconds off) if it clicks on then off right away (a second or so) and stays off for a few seconds, or doesnt come on at all, you could have a bad switch, bad pressure sensors (wont let the compressor engage if not enough pressure is detected in the lines)

good luck
