No experience with this at all, but here are a couple ideas.

Are you saying that your fan is turning on intermittently? If so, I'd guess a loose wire, flaky relay, or somethin is up with your hvac panel thingy with the knobs.

Maybe check to make sure the plug on your fan is tight, find out which relay controls the fan and replace it, and go from there. Just my guess.

If your fan is turning on, but no cold air, I have no clue, but it sounds expensive.
Im going to check the relays n fuses this weekend. I will also check the connections, the fan isnt turning on when i have that problem its just the noise that it makes when its turn it on but nothing turns on except for the ac light. Thanx for help
