How do you remove a blower motor resistor from a 2004 Cadillac deville


No resistor - there is a blower motor control processor attached to the blower motor housing under the dash on the passenger side. You should be able to get at it by removing the kick panel under the dash - just follow the wire harness to the processor connector.

My 98 deville says theft system problem car may not restart and i have checked the ground. i also have put an after market stereo and alarm in could this cause it? what is my problem


I would suspect the problem is with the aftermarket alarm. I would consult the manufacturer of the alarm and see if there are any problems with compatibility with the OEM alarm.

This is very common i've done tons of these, its the blower resistor module, replace the blower resistor module and that will solve your problem. this part is located under the hood on the firewall on heaterbox, this costs about $200.00 for the part and heres a picture of it. hope this helps.f2aa535.jpg

Follow the wires from the blower motor back to the blower motor resistor, normally only a few inches away and held in by a 7 mm screw. Replace it

Yes i have juice to the blower motor, but it dont blow all fuses are good, freon is good


Cadillac 1999 DeVille
If the front blower motor is not running with battery level power to it, you may have bad blower resistors which controls the speed of the motor.. Unfortunately the resistors are built-in the motor. You may have to replace the motor. If you remove the motor, you can recheck it by direct wiring power to it. OR you may have loose wires.
Also check the Heater and A/C Programmer module.

Here's some info I found from another posting.

Red is positive 12 volts coming from fuse of circuit breaker. The black wire is either the ground or the main hot wire going to the blower motor (3 pin connection only), and the gray wire (if is is small in size) is a variable voltage coming from the body control module requesting speed for the blower motor.The blower control module varies voltage on the main wire going to the blower motor, supposedly in accordance with the requested voltage from the body control module. Usually if all fuses are okay and present on the apprpriate wire of the blower control module, the a blower motor that will not run or stays running after the key is turned off is the fault of the blower control module. If the blower control module has failed the the cause must be determined (over amping blower motor) or else new blower control module may fail when powered up.Usually blower control modules have more than three wires. Usual connections are: B+ (battery voltage) GND (chassis or engine ground), two large wires going directly to blower motor (can be any color, but are usually 10 guage in size), and an optional wire that reports voltage level back to the body control module.

Heater fan will not switch off when car is running or not. Had to pull heater fuse to stop.


It has a blower control module instead of a resistor mounted in the box next to the blower motor. The blower control module is bad
