2005 Lacross blower motor question.it has been intermittently working.if i hit the pass. side dash it will come on.now it won't come on at all.


Does your Buick have manual or automatic HVAC system ? It's not a relay , probably the motor ! But testing is the only way to know for sure ! Videos on youtube showing how to troubleshoot . Do you know how to do basic automotive electrical testing ? Videos on youtube on that subject as well . Disconnect wire connector at the blower motor , an jump the blower motor directly . If you have hit it to get to work , the blower motor is bad !

Blower motor not working on 2005 buick lacrosse cxl


Blower operation is handled by the HVAC control module which gets its power from the 10A HVAC fuse in the instrument panel fuse block. There is a blower motor control processor that gets its power from the 30A BATT MAIN 4 fuse in the underhood fuse block. The HVAC control module sends speed signals to the blower motor control processor which turns on the blower motor at the selected speed. Note that there is no relay involved. If you check the fuses and check the path to the blower motor you may find that the motor is OK and the trouble is somewhere else

Blower motor will not shut off. 2005 Buick LaCrosse


There is a bulletin for this fix.The bulletin number is 05-01-39-001A.This pertains to the blower motor staying on after key is shut off.What you will have to do is replace the blower motor resistor module and install a capacitor in the wiring.Part number is 25073556 for the capacitor.The blower motor is on the right side under the dash.Just remove the insulator panel and you should be able to see it if you look up into the dash.Or turn it on and listen for the blower motor.Disconnect the connector to the blower motor control module.Find cavity a and c.Cavity a is negative and cavity c is positive.C is red and A is black.Splice the positive lead of the capacitor to the red wire and the negative to the black wire.You should use splice sleeves and solder the wire on.Hope this helps.Good luck.
