I have a '95 530i with stock R-134a AC. This is my 4th Summer and when I went to crank up the AC for relief, I was rewarded with a blast of warm air. The compressor runs which I imagined meant that I had some refridgerent otherwise the cut-off switch would have disabled the clutch so I bought a recharge kit hoping for a quick fix. Step one was to measure the pressure on the low side which indicated 80 psi which, according to the guide on the kit means, game over - go to a mechanic. Searching past articles on the board it seems that AC repair is mondo expensive. Does anyone have any suggestions?
