My a/c blower was working perfectly, I turned off the car. Next time in the car there is no a/c fan. The compressor starts when the a/c button is pushed. The #7 fuse is good (this is the right one?) Is there a relay for the fan somewhere. Any idea of what could go wrong? The fan was working perfectly with no unusual noise or other symtoms. Any help appreciated..I'm in Phoenix and it is HOT!!!
