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.

Check the fuses. Check the ground behind the passengers side kick panel. Give the blower a rap. If that starts it, you need to replace it.

OK - the good news is that most - if not all those codes were probably triggered by a LOW VOLTAGE condition at some point - at this time - clear all the codes and see if any return -

the blower motors are not monitored - so they would not set codes -
but if the controller malfunctioned - it would set codes -
the good news - no codes - means the blower problem is probably within the blower -

go back and read Ranger's post - #2 -

the known common problems are worn brushes in the blower motor -
and bad grounds -

if it turns out to be a bad blower motor - amazon.com has great prices -
and you will be happy to know -
replacing the blower motor on your car
is probably the easiest part on the entire car to replace -
well - almost -
