My compressor just stopped running. The fuse is fine. I don't even hear the clutch try and engage. Is there another fuse in the white connector above the compressor? It's getting warm here and the top down doesn't cut it in 100+ degrees. Any help would rock.

Any unusual sounds or behaviour from it recently, like roaring or being engaged too long. Mine is kicking in for about 20 sec. in 15-20 sec. intervals when working normaly. If you havent heard any bad noise coming from it recently, try checking temp sensors. Probably some A/C specialist should track them all and try overriding them to see if some of them is preventing compressor to engage. I know for sure there is one behing glove compartment, attached to vent pipe, but that's not the only one. Sounds definitely like electronic problem if you say that clutch is calm too.

since we're on this topic; my ac compressor runs fine, as far as the AC is concerned. But the clutch &/or bearings are going. when it's on, she rattles...

Speaking to the saab mechanic that I go to, new clutch is like $450 and the compressor is around $600...

Does this information sound accurate?

As of right now, unless it's incredibly hot, I just hit the 'econ' button upon startup. More power to the wheels, anyway.

thanks,
bny

If the pressure is too low or too high, the clutch will not engage. This can be checked with the gauge that comes with a recharge kit from Napa and other stores. In other words, if the refrigerant and oil leaked out completely, the low pressure switch will not allow the compressor to run to keep it from seizing up.

There is also a relay in the black fuse and relay box under the hood. Label is on the box cover.
