Air Con probs

2002 330d with no cooling air the drive belt is fine, the fan works, and the pump rotates when A/C is selected. Does anyone have an idea of what to look
at?

Are you sure the clutch engages when you call for cooling? Check the accumulator and look into the little circular glsss sight glass. You should see fluid flowing usually with bubbles. If not, you may be low/out of refrigerant to where the low pressure switch (safety) is stopping the compressor from engaging.

Sure, that's an easy one. Look for an AC Repair shop!
Seriously. You've ruled out the big, obvious stuff. Time for an expert opinion. It will undoubtedly involve doing some work with the refridgerant and you are not qualified to do that.

Not only that - he's probably not qualified to work with refrigerant either..

You two have gotta be kidding. Didn't you know that you can buy R-134a refrigerant over the counter now, in a can? You can get a big can for about 10 bucks at many places that sell even a relatively small selection of auto parts. Comes with fitting and hose too! This job is now easy and cheap. If only they'd start selling kits for home AC's.....

Yeah, and just dumping in another can of *refrigerant* without knowing the present charge level is one of the best ways of insuring you'll be spending even more money when you go to see the AC specialist.

Do tell. When the air is no longer cool, it needs a recharge. I have wife sit in car, and when air is cool, I stop charging. Pretty simple.
This car needs about one can per year that lasts all summer. Some years back, I took this car to an AC "specialist" because the compressor was making a little noise, and the air wasn't cool. He said I needed a new compressor...about $600 I think he said. I didn't bite. Still the same compressor (no longer makes noise) and cool all summer on one can of refrig.

And if there's a sight glass, the job is even easier. Get the car runing for 10 minutes with AC on full. Slowly add 134 until the bubbles almost disappear from the sight glass. Never turn the can upsidedown. as you'll damage the compressor with liquid.

Yep, this car I was talking about does have a sight glass, but I never could get much info from it for some reason.

So that's the reason the instructions always say that....never thought of that.
