Hi,

We are having trouble with our 2001 VDC Outback A/C. We took it into the shop today and after two hours, replacing gaskets and $90.00 we still have no A/C.

The car was not cooling air normally, not blowing hot, hot but damp and warm.

The tech said there was only 2oz. of r132 in the system and there were gasket and valve leaks. He was supposed to replace both, but only listed the o rings now that I look (may just have forgotten). He says on the bill:

"Work requested - a/c does not cool, Work performed - freon is low. Leaks at compressor hose o rings. Replace o rings and recharge system. Pressures are equalized in low and high side of system. Compressor is running. Low side increases in pressure when throttle is increased. Recommend replacement of dryer assembly and expansion valve and retest pressures. May require compressor replacement. Evacuated freon from system."

This is just our local garage, not Subaru specialists and reading here I found out about the Compressor Rev Sensor. I have an ohm meter and would like to test it, but I cannot find it. :p

Can anyone tell me where it is? Do you have to remove the plastic covers to reach it? Does it even sound like this may be the problem?

Thanks for any help!

P.S. I have looked at the do-it-yourself forum, looked at the forum search results and the bulletin with the picture, but still can't figure out where it is. :-*

Okay. This is the same one I have.

I'm sorry to be such an idiot.

I looked at the car earlier with this printed out, it looked like this was maybe located in the upper left quadrant under the hood, but I would have to remove panels the find the sensor? Is this correct?

You need to remove the large plastic engine cover, 4 bolts and then it slides forwards, not sure beyond that.

Don't get talked into a compressor replacement. These units rarely fail. You have to run them without any oil for a long time to kill it.

If what the tech put on your invoice is correct, it is generally a restriction somewhere or too much refrigerant in the system. If its on and cycling, the pressure switches are working and its moving something.

I would have them recheck the amount of refrigerent in the system. A .25 lb too much will cause what you describe with the warm and humid air being blown out. This indicates that refrigerant is moving through the system, moisture is being drawn to the evaporator and when the pressure rises cycling the AC compressor off, the water is blown out the vents as the evaporator warms back up.

Thank you

Thank you for all the help. I will work on the cover tomorrow and see what I discover.

Thanks!
