My neighbor has an 05 S40 (w/ digital climate control) and her AC isn't very cold. I've done everything from rebuilding a short block (hammered a rod bearing in my VR-4 :-/) to replacing synchro's in a Getrag tranny, but A/C is the only thing I can think of that I've never messed with (ie. never broke .

Any tips on where to start diagnosing? When you turn the AC on you can hear the compr. turn on and put a load on the engine. Where should I go from there, AC recharge kit? Anyone know of anywhere to download the factory service manuals?

Thanks in advance for any tips.
