Question about Buick Cars & Trucks
Hello Joyce , lets see if you can give us a little more information first . The front windshield defroster doesn't work ? When you change the mode switch does air come out of the center vents , the floor ? What I'm getting at does the air flow change when you change the mode switch ?

your problem is in the window..........if you are getting 12v to the wires that connect to the window the lines in the window must have a break in them ............. they must conduct the dc volts to complete the circut, the lines heat form the voltage running through them thus ridding your window of fog and ice
hope this helps...........thanks for choosing FIX YA!

I found this on another site... it seems like a credible post so I thought I'd share... I'm going to check it out next weekend.
"Just an FYI. The rear defroster issue is due to a bad Antenna Buffer Module / Antenna Module. The power to the rear defogger goes through a module that separates the antenna amplifier signal from the 12 volt power to the defogger. The defogger elements also act as the antenna. The module is behind the rear pillar right behind the rear passenger door. The inside plastic has to be gently pulled off, the seat needs to be folded down to get the lower part of the trim off. One screw at the bottom, unplug the wires... (two connect to the window grid, mark which one is which)... and the module is free.
The module may require re-soldering of the pins joining the main power connectors to the internal circuit board. If you feel you can do this (or have a friend do it for you), go for it... else get another module from the dealer to replace it."
This is the most credible of the several posts that I've seen talking about this module. I know its there... I saw it yesterday when I was working on the car.

those can be tricky to solve. get in the back of the car and look for a connector on the window. some times for some reason they let go. if it has let go then visit you auto store and ask for a fix there are a few products that are cheap. if it has not let go then if you know how to use a multi meter check for voltage on the connector/s if theres voltage then there is a break in the defroster somwhere

Sounds like a stuck motor. Hold the switch down and slam the door shut. This will usually break it free. It will most likely need a motor though.
