Question about Buick Cars & Trucks
The heat works but the fan doesn't
Then you either have a blown blower motor relay or the blower motor itself is toast.

My 2005 Vibe did the same thing it was the heater resistor. It is located to on the firewall behind the glove box on the lower left side of the blower assembly. Two 5.5mm screws hold it in place (1/4 inch socket works too). I used a socket attached to a socket swivel to replace mine in under 10 minutes. Heater now works as good as new. I purchase mine online for $30 from rockauto.

blower motor regulators go bad because of the switching between low and high speeds. some times these are under the dash and require tiny hands and lots of patience.

Alot of people have the same problem with the fan switch and blown bulbs. There really is no fix for this. Jeep really screwed up when designing the heater control assembly. The cheapest solution is to buy another unit off Ebay. Can always go to the dealer but be ready to PAY for there mistakes.

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.
