Question about 2002 Buick LeSabre

1 Answer

My A/C fan will not work always

I have a 2002 Lesabre Limited with climate control. Sometimes the A/C fan will not start right away; sometimes it wil start after the car hits a bump in the road, but I am not sure because sometimes it starts normally. It seems the computer that controls the fan works ok, once it starts it will never stop on its own ( that is why I am not sure about the bump, a flaky connection would disconnect sometimes ) and I can control everything normally. Can someone please tell me how to get to this fan and its control unit to see which is bad ?

    I have a similar problem that had also involved hitting a bump to "jump start" the AC fan to blowing cool air. But, it is the same with heat and windshield defrost.

    Now, however, I'm not getting any air through the vents when I hit the AC. I see the solution you have written, would it also apply to me?

The fan should be located under the dash on the passenger side. also make sure that the reostat connection is nice and tight this controls the fan speed and sometimes it can come loose due to vibration.

1997 buick lesabre limited, blower motor works sometimes.


More than likely a bad speed control. These are usually mounted inside the car near the bottom of the AC box. Another possibility is a bad connector under the hood. The offending connector is usually located on the right side of the car near the blower motor area. Look for a connector that has one large red or orange wire and two smaller wires. I have found these connectors burnt up on many occassions.

My '99 buick lesabre climate control blower motor, sometimes, will not come on and sometimes it works fine. What will cause this problem?


First check battery to motor ground, battery to body ground and motor to body ground strap for corrosion under bolts. Bad ground can cause all sorts of electrical problems. If these are ok, the most likely culprit is the blower motor itself or the switch.

Air conditioner blower does not work all the time, how to fix? Blower may or not come on when it should. It sometimes goes off when driving. Sometimes it can be jarred to make it start working.


The connections to the blower should be checked along with the climate control buttons on your dash. I would also check any fuses as well.

Climate control push buttons work sometimes and not


The climate control cpu could be going bad. My Riviera had a fried plug that went to the climate cpu and I replaced just that. To check it out it can be found behind the glovebox.

2002 Gr Cherokee Ltd. - Fan not working on Heat or AC -any speed!


I have the same problem... If you have the auto climate control like I do there is a resistor at the bottom of the HVAC assembly right where the passengers foot would go. Be careful playing with these wires but you can wiggle them around and sometimes it worksish. But I've seen jeeps that the entire inside has burnt out because of that wiring. It is hard to find this part without going to the dealership stores say they can order it and then call later and say they cant. But you have to replace both the wiring and the heater resistor which will be a good days worth of work.

Climate control varible speed fan not working


According to the schematics on your vehicle, it has a "Blower motor control processor" either built in to your controls, or in line between your controls and blower motor. Yo may get real lucky and find some dirty connections in that area, and get away with cleaning & re-connecting, but I wouldn't get my hopes up too high. You may end up replacing the processor, as it regulates fan/blower speed.
