Second, problem, not as annoying as the headlight ticking (other thread I created). When the car starts it blows extremely warm air. If I leave the A/C on full blast on low settings and drive around for a while it starts to equalize and I can roll the windows up and enjoy moderately cool A/C.

I tried to refill the Freon, this worked for about a week or two of extremely cool air, no problems. Then it went back to the previous problem. I would think it is a leak but again, if left running for a while the temperature does adjust.

I don't have the expertise to be looking with UV lights and Freon dyes for hose leaks or compressor leaks. I've read that using the Freon repair kit sealers is extremely bad for you car and can mess it up.

I used a Freon Kit with 12a (which now I think might have been the wrong refridgerant) Didn't drain just put the can on and let it go to a good reading on the gauge. (Followed a video on youtube by a guy named fupabox)

It's an old car so don't want to spend 1000+ on just fixing the A/c when I pretty much got the entire car for that cheap.

Your last paragraph says it all----quite your whining,roll the windows down and drive the car, because you can't afford to drive a car with AC!!

Plenty of things can go wrong and I had one in my older W202 which cost me plenty of $$$$

Ya man, you are super cool and helpful..........must have a bunch of friends since you spend your free time trolling in a car forum

Thanks for the decent reply DRB, ya i figured, old car, but still a tank.

Common problem is the compressor. Have you tried to do an analysis of the HEVAC and possible codes. You can also do a review of all the operating details. I'll post some YouTube links in a moment....

I did look at some of the codes. I assume you mean when you press and hold the rest button and you get different vent temperatures and coolant temperatures. Wasn't sure what they meant or if they were normal readings or if they were completely off, had nothing to base the numbers off of.

I have no AC what-so-ever. Put it on a vacuum check and it didn't find any leaks, so I refilled it (R134A by the way), worked great for a week or two and then started dying again. The vacuum check was not able to account for a leak in the compressor or if the valves themselves on the high pressure or low pressure ports were leaking. I'm eventually going to do an AC overhaul and replace the compressor along with other components. It is also important to add the proper compressor oil when refilling if you fully evacuate the system.
