Re: ac system
no it doesn't. he said he tested it by running battery voltage to it and it turned on. the a/c unit is either not telling the compressor to turn on, or the pressure switch is preventing the signal from getting to the compressor. .
how exactly are you charging the a/c? did you pull a vacuum on the system first? do you know how much refrigerant you've put in at this point? this is why i recommend highly having someone with the right equipment work on a/c. i just had my a/c system worked on the other day because i recently replaced my heater control panel. my buddy has one of these and it makes the process much easier.
what this allows you do that you can't do at home is pull a vacuum, purge the lines of air, and know exactly how much r134a you're putting in. so if you don't have access to one, it might be smart to pay someone who does.
this is of course assuming the problem is soley with the proper filling of the system. when you hit the a/c button your condenser fan should come on, and your compressor should kick on (assuming pressure is adequate). since you may not have appropriate pressure in the lines check both sides of the pressure switch and determine if one of them has battery voltage. if it does, then the a/c switch is whats stopping the compressor from turning on. that's either because its functioning and its not detecting the proper amount of refrigerant in the system, or its malfunctioning and not providing continuity when it should be. if you do not have voltage at either said of the switch, then there may be an open wire somewhere, a/c thermostat may be broken, or the heater control panel could be faulty.
