A/C Help
Hi I'm new here and would like some help if possible the first thing is my A/C was blowing warm on the driver side and cool on the passenger side so i had it checked and charged and it was cool for about a hour and now its warm on both side and now the the A/C light will not stay on and i had a problem with the turn signal sometimes not working until i hit the hazard button on and off and the lighter doesn't work not sure if this is all connected to the same problem Thanks

Low battery, possible air bridge off the MAF(assuming you posted the two C-codes wrongly), PASS-Key issues and etc...but nothing obvious with the AC. Sounds really like you are low on refrigerant. Clear all of the codes and then check again. Suggest you take the car to a professional AC shop so they can properly check the charge levels. If the other codes come back, start with the battery.

i took it to have check and was told it was low and after it was charged the A/C light will not stay on could that be a safety feature because it may be too pressure on the A/C from the mechanic putting too much refridgerant.

A professional shop "should" know what they are doing. R134 systems require a specific amount of refrigerant based upon the ambient temperature outside at the time of filling. If they did it right, they would have evacuated all of the refrigerant and pump back back in a specific amount for that system. Too low or too high, it will not work.

The high side ports are known for leaking especially after putting guages on. Make sure they checked it and if they didn't completly evacuate the system and pull a vacuum before charging the system will not be charged right. You can't top off 134r systems. They should have put dye in with the oil as well.

yaeh they put the dye in and they said it had no leaks and charge the system and it was cold for about an hour then the car sat for a while then only hot air and if you press the A/C switch the light will stay on just for a second then goes out and the A/C will not work

Sounds like a leak to me. AC will not stay on once freon leaks out of system. Not good news if the dye is not showing up anywhere visible, especially if leaking that quickly. I had 2 shots of dye, vacuum test, soapy water test and no visible leak. Those are all the symptoms mine has but mine is the evaporator. Big chore to repl so that will have to wait until winter. I hope it is not that. Good luck.

After repl compressor, seals, accumulator, shrader valves, orifice I determined it was the evaporator. I am in the middle now of repl - 15 hr job. However, the evaporator I ordered did not have the seal kit, so I have been waiting since Jan 3 on that. Here is where I am at now:

Hey! That looks familiar!
Yea, the job isn't really that bad but it's a LOT of stuff to do. I'd stick in a new heater core as long as you've gone that far. If you think this job is irritating, how do you think going back in would feel?
Mine also was a nightmare, though I know that doesn't make you feel any better.
