SOURCE: Heater/AC Fan does not work in our 1998 Buick Century

Fan will be under dash on passengers side , Removing glove box might be needed, Gm also uses a blower resister ro control fan speeds. First check your fuse and then check and make sure your getting 12 volts to the terminal at the blower, You could have a blown fuse, a bad switch, or a bad resister , if your getting voltage to blower motor then most likely it will be the motor. These are not to difficult to change. I hope this helps, please be aware I can only guess at what the problem is from my past experience.

SOURCE: Buick Century wipers out of sync

You could also see if the bolts holding the wipers on came loose from the snow and ice. Pop the cover off, loosen and straighten the wipers where they should be and tighten.

SOURCE: Buick Roadmaster 1996 AC not working

The linear actuator that regulates the blend of air between hot and cold was broken and needed to be replaced. That was my suspicion. Fuses were all good. Relays were all good. Compressor pump cycled. Freon was "proper". Dealership only charged about $400 in parts and labor to confirm my guess.

SOURCE: Blower motor vent selection switch not working

the hvac selector switch in the dash may be the problem.You need to remove the switch and look at the connector on the back of switch,see if there are any burnt wires at the connector or switch.It's all electronic and the switches have been known to burn out on this and other model.

SOURCE: AC/heater fan on 1992 Buick LeSabre only works intermittently

Could be a bad control switch, relay or connection and ground at motor itself. Since it's intermittent, check voltages when it's working, then again when it's not. Wherever voltage stops, that's what you need to replace. Don't wait on this...when completely inoperative it gets much harder to find the problem!

94 Buick Roadmaster AC fan blowing hot and won't shut off


If you have climate control it could be the main processor. Something could be shorting the blower relay to keep it on. You would also need to check and see if the system is still full of freon.

1995 Buick Century blowing hot air.


A mechanic would check the system with a set of pressure gauges. If the compressor is running, the low side would read around 30psi and the high side would be around 250psi. That is how you know if the system is full of freon or not.
You may have to get a professional diagnosis to proceed. If you replace the compressor, the accumulator needs to be replaced and a vac pump is used to pull all of the air out before the freon is added.

Ac dont work and the radiator fan dont work


check if you have enough freon gas in the air conditioning system so as to get pressurized and by doing so the fan should start. Visit a prop[er air conditioning fitting and service garage for help.

Compressor keeps kicking off 1999 Buick Century AC


Your ac system is most likely low on freon, or the cooling fan is not working.
When you turn on the ac the cooling fan should stay on.
If it stays on then you are low on freon.
