MY FAN QUIT WORKING W/O ANY WARNING SIGNS. MY GUESS IS I BLEW A FUSE. I CHECKED THE HVAC AND A/C FUSES UNDER THE HOOD AND THEY ARE FINE. I'M TOLD THERE 'MIGHT BE' A FUSE BOX IN THE CAB. IS THERE? IF SO, WHERE? I CAN'T FIND IT.

ANY OTHER FUSES TO CHECK TO CORRECT THIS PROBLEM?

thanks for your help. seeing if there was power was my next thought, but it seems so obvious the way it went out that it was just a fuse.

any idea what the most likely fuse # it could be if i do have power?

thanks again
