I'm attempting to fix the A/C on my wife's 1998 318i. Static pressure in both the high and low ports is > 80psi. (Is this too much?)
The fuses and relays are fine. I get >12v to the compressor's connector plug. But the compressor clutch does not engage. If I apply 12v directly to the compressor's connector, still nothing.
So, I followed the how-to above. There was quite a bit of corrosion on both mating surfaces, and I got it all cleaned off. But still no clutch engagement. The only thing I can think of is that the compressor clutch's mating surfaces are much more worn than what is in the pictures of that how-to (nearly flat). But shouldn't it at least attempt to engage (even if it slips)? |
