Buick Lesabre Climate Control And Blower Not Working

Details: Category: Buick LeSabre Problems Answered

2000 BUICK LESABRE,CLIMATE CONTROL MODULE,BLOWER MOTOR,AC, WILL NOT FUNCTION. NO VOLTAGE ON TERMINALS AS COMPARED TO MY 2002 LESABRE. CHECKED ALL FUSES IN ENGINE COMPARTMENT & UNDER REAR SEAT. NO WIRING DIAGRAM FOR REFERENCE.

Answer: Without a wiring schematic, this would be very hard to diagnose. We do not have one to send to you. Be sure that the systems in the two different years are EXACTLY the same- terminals, wire colors etc. You can try Autozone online or any of the repair manual website.

If the fuses are all good, you will have to trace down the wiring from the fuse to the control head. You may have a broken wire or corroded terminal. Have seen water corroded terminals under the drivers seat carpet. They show as a green corrosion.
