Air conditioner

[emperor_of_weasels]

I have a 1999 New Beetle GL. It is a 2.0 AEG gas powered engine. I love this thing to death but there is something wrong with the airconditioner. When I first start out the compressor kicks in and the air is cool. But after a while the compressor kicks off and and it starts to heat up in the passenger compartment. The ac button light is still on when this happens. I have tried to turn the switch on and off but the compressor doesn't come back on. The radiator is full, right below the max on the resivoir. I have also checked the pressure in the low-side charging port and it is good. I was thinking it might be a relay but ifit is I don't know which relay to change out. Any help would be greatly appreciated.

I found out what seemed to be wrong with my air conditioner. Under the hood there is that fuse box over the battery. I have read that a few people have had this same problem and they said it was this fuse box. What happen is that instead of the fuse shorting out, it melts into the fuse box. This is why it sometimes came on because it is still connected. The fuse that has to deal with the a/c is the one to the far left, but I changed them all just to be safe. I drove it around last night for a good 30 min's and the a/c hasn't went off yet... still crossing my fingers. String a reply if this helped you!

What is the pressure on the low side? Should be 30-40.

Thanks for replying. I checked the pressure and it was aout 33*F. Now the fuse box over the battery has gone out since I changed the fuse. It almost caught fire. Is there a recall for this? There should be!

Sorry that is suppose to be 33 psi... sorry I am a food inspector. You kind of get use to putting "*F" behind numbers if you know what I mean.

No recall for this, but for some reason it only seems to happen on beetles...??? weird....

THats a good normal pressure for low side.

Do you know which relay is for the air conditioner. I wanted to check it out just to be on the safe side. Thanks for the help

I think its actually the switch itsself.

I am a GM/Toyota dealer, we are getting NO help from local VW store. I need a diagram of a/c. we have 2000 Beetle with NO power to a/c compressor. All relays and fuses are good.

thanks

So it is the switch, but it lights up. I got a new fuse box and I put it in. What could I do to check the switch out to see if it is faulty? Could this bad switch case the a/c to go off and on. Thanks alot for all the help!

We found our problem, fyi... the relays in the fuse box were rusted up pretty bad. cleaned all the terminals and she fired right up. good luck with yours....

ps.. that is a tech for you, asking for help before they actually take the time too look at a car...

Where are the relays? Do you have to take out the fuse box in the dash? Which one is for the airconditioner? Thanks for the help!
