Its possible its the fan motor itself. you could check for power and ground at the motor. If you have + and - bump the motor to see if it will run. If you dont have + - then it could be the Blower motor Resistor.

Usually This is a bad blower motor. Check power and ground to the motor. When a resistor goes bad that controls the motor you will usually only have one speed.

that's normal when hot, but should't run down the battery. if severly overheats ffnd/fix that problem. the other will probably dissapear . if not excessively hot then the fan heat sensor is faulty....

2002 Buick Regal AC/Heater fan switch will not work on all speeds AND goes on and off on the speeds that do work. When it goes off it will usually come back on if you bump the side of the dash.

It sounds like something is wrong with the switch itself and its contacts--it may be dirty inside--maybe somebody spilled something on it or water got in. Generally, pros say to have trained mechanics deal with A/C. A/C really requires special diagnostic gear and expertise. That's the safest bet...replacing your A/C compressor proves really expensive--keep it going as long as possible....

I have a 1999 Buick Regal cooling fans do not run

check for power at the plug that attaches to the fan motor. if it has power then replace the fan. if not then trace the wire back to the relay to find the short.

2000 buick regal blows high fan fuse as soon as it is put in with car offf

I would disconnect your blower motor resistor then try fuse again, if it does'nt blow then it is either blower motor or resistor,these resistors are common for going bad/and or blower motor. Good luck let me know if you need more info or if this didn't fix it, I will research it more for you

My blower fan for the vent, AC and heater and defrost, on my 1999 Buick Regal made strange loud screaming, screeching sounds before it quit altogether. Which fuse would I replace to make it work again?

If the motor was making those kind of noises it is most likely the motor itself needs to be replaced. It turns on bushings instead of bearings and they wear out making that kind of noise when they do.Hope this helps.

2002 buick regal blower motor trouble. voltage at motor is 4.29 ,that is the same at the fuse. I have replaced thebrlower resistor . and now have battery voltage at the connector for the blower. fan still...

The fan motor may need replaced. Over time with low voltage electric motors go bad just as with high voltage. More than likely it has burned out. You can try replacing the contacts in the motor, but I believe it is easier to replace it.

All windows wont roll up or down on 2000 buick regal

contacts in window motors sometimes get dirty from lack of use. Take a rubber hammer and beat under the interior edge of the open door while working the switch (don't be gentle). It it works, exercise the window more frequently.
