2005 Buick LaCrosse Question: How do I replace blower motor?
The blower motor on your 2005 Buick LaCrosse is located under the passenger side of the dashboard. To access it you must remove the lower insulator panel. There are 3 or 4 screws that attach the blower motor, One you remove the screws you should be able to remove the motor and fan assembly. Before replacing the motor look for debris in the fan which can cause noise and vibration concerns. - Jim Taddei

my blower only kind of works when i get on the highway. It never works on the street. had a smiliar problem in the summer with the A/C. it would only work after i hit a speed bump really hard.
