Well i first tried all the identical relays in the box in that spot, none worked. Next tried the hitting thing on the concrete, didn't work. That same relay works in other spots, but does that necessarily mean it's NOT the relay? Is there something special about the 02028 part from the dealer that is worth spending the 73.81 on? I bought a replacement for nine dollars from O'Rielly's and it didn't work in that spot but worked in a different spot. A lot of ppl say that the 02022 and 02028 part numbers both cross ref to the same part in their store (Auto Zone, NAPA) so i don't know if it's the right part. I also tried replacing the air cabin filter, which some ppl have said worked for them, but didn't work for me. Thanks for the info on the compressor, my mechanic said he doesn't know and to take it to the stealer but i DON'T WANT TO, i'm very spoiled with my HONEST mechanic and don't trust anyone else!! Oh, well.
