Hey guys, Im stuck with a huge problem... My AC is not blowing Cold... I've checked the Refrigerant levels and they're perfect... it's still running R12 Refrigerant... should I switch to the newer R34... and my AC belt and AC Compressor is working from what i see... I hear there's a relay or some crap I should check... what other things may be wrong... I have a young Baby daughter I take in the car often... in Miami Heat... so I need to resolve this quick.

If you have R12 and its blowing warm, your levels are fine, then changing to r134 wont solve much. Next make sure the compressor is kicking on. It goes on and off.

It depends on the shop on the retrofit there is a cheap way which is evac the system put on R134 fittings and add some pag and some freon and be done
The right way to do it is replace the expansion valve the liquid tank and the compressor then flush the condenser and the eavp core and lines then add fresh pag to each roughly 1oz to each part then charge it up with 134
I have done both and can say I have never had a car come back with a locked compressor from mixing the 2 different oils, I'm not sure the conversion percent for 12 to 134 but you can tell by the pressure and by looking on the sight glass and tell if it is full
But if check to see if your compressor is cycleing on and off but it sounds like the expansion valve is stuckComment

if your system is full check the pressure switch. if it goes bad it wont allow the compressor to kick on and cool the cabin. the switch is on the front driver side of the car where the eye for the ac system is. a way to check it is by putting a wire or paper clip in the connector so see if the compressor kicks on

So, im figuring its something like what DaGrk said... and Im looking for this switch and can't find it... can u be a bit more specificComment

have someone put some dye in the system and then go back like the next day and they'll look at it thorough this star wars looking mask w/ a special light to see the dye. My leak was coming through the discharge line, the one that goes way into the front of the car underneath.

You use UV light and dye the switch is on the liquid tank(dryer) un plug it and jump it off, put a wire in the connector and see if your compressor comes onComment

ok just got back in from checking on my car, the switch is right behind the the driver side high beam head light and right next to it is the ac high pressure port

yea i have a problem with my AC too
my uncle for some reason thought it be a good idea to straight wire my main cooling fan to the radiator. well after that happend it knocked out my AC & Heater and none of the console lights will light up when you press them.
the AC will turn on but the blower wont blow any air in.
Whats the problem? bad Fuse? or blown sensor?

Ok... the the compressor DOES turn on... I hear a obvious click when it does go on... I also see the refrigerant going through the Eye looking thing... what else can i check... is there like a sensor or somethingComment
