On my 2004 DTS. My wife went to work the other night the heat was blowing just fine, but when she came out on break to sit in the car, the blowers wouldnt work, front or rear. it still heats but neither of the blowers will work. i was wondering if there are any fuses, relays etc... that would make both stop working at the same time. i can hear the front one turning ever so quietly. also the rear control display just flashes. anyone else having this problem? i couldnt find anything in the threads and want to avoid the only caddy dealer in town because i seem to get my car back in worse shape every time.
