Replaced my Blower Motor Control Module in my 2006 Yukon XL Denali, but has a weird problem.?

Question

I just replaced my Blower Motor Control Module for the fan speed control because the fan stopped blowing all together after work intermittently for several months including not turning off after the car was off.

After I replaced it the air kicked on and was great. The only problem now is this:
When I turn my car off with the fan still on and restart the car the fan wont turn on.
When I turn my car off with the fan turned off and restart the car the fan will turn on no problem.
Seems like a very weird problem to me? Any Ideas?

My car is a 2006 Yukon XL Denali, the part I replaced was

Answer 1

those fans have their own sensor that tells them to to come on and go off which is unlike the old fans that ran all the time because the were belt driven by the engine when the car starts the fan has to run and when the car is off the fan stops.

i have heard many cars that where stopped and parked have the fan come on as i was passing by. like i said NOW they are run by sensors and turn themselves on and off when required.

hi Eric! right it somewhat is the technique for changing the blower motor on a '05 GMC Yukon XL: a million) If geared up, eliminate the sound insulator panel. 2) eliminate the blower motor insulating cover screws. 3) Disconnect the electric connector from the blower motor. 4) eliminate the blower motor insulating cover. 5) Pull the retaining tab down jointly as turning the blower motor counterclockwise with the intention to disengage the blower motor from the heater/ventilation module. 6) eliminate the blower motor. -setting up- a million) deploy the blower motor. 2) deploy the blower motor to the heater/ventilation module. turn the blower assembly clockwise till the retaining tab locks into place. 3) deploy the blower motor insulating cover. 4) connect the electric connector to the blower motor. 5) deploy the blower motor insulating cover screws. 6) Tighten the screws to fourteen inch lbs. (a million.6 Nm). 7) If geared up, deploy the sound insulator panel. stable success!

Answer 5

I'd want to see a schematic/diagram of the circuit bec another module such as the BCM could be faulty.The module you purchased could of been a new or refurbished module and it could be detective.







Hope that helps and best of luck.By the way parts source offers free diagrams/schematics of different circuits for assorted vehicles and you may want to see if they'll print you out some free diagrams/schematics of the heat/AC blower motor circuit.

hi Eric! right this is the technique for changing the blower motor on a '05 GMC Yukon XL: a million) If equipped, do away with the sound insulator panel. 2) do away with the blower motor insulating conceal screws. 3) Disconnect the electrical powered connector from the blower motor. 4) do away with the blower motor insulating conceal. 5) Pull the preserving tab down whilst turning the blower motor counterclockwise with the intention to disengage the blower motor from the heater/ventilation module. 6) do away with the blower motor. -installation- a million) installation the blower motor. 2) installation the blower motor to the heater/ventilation module. turn the blower assembly clockwise until the preserving tab locks into place. 3) installation the blower motor insulating conceal. 4) connect the electrical powered connector to the blower motor. 5) installation the blower motor insulating conceal screws. 6) Tighten the screws to fourteen inch lbs. (a million.6 Nm). 7) If equipped, installation the sound insulator panel. good success!
