Hogboy Posted April 25, 2011 Share Posted April 25, 2011 Anyone ever have the motor rebuilt for the rear window fan? I would like my to work. Not sure why I don't drive her in that kind of weather. Anyhow, any thoughts? Link to comment Share on other sites More sharing options...
allbowtie Posted April 25, 2011 Share Posted April 25, 2011 My original still works, but I never use it. All it does is just blow air around. I think it must have been a "must have" option that served no practical function. It just blows cold air on low or high speed. Go figure.....

overdrive Posted April 26, 2011 Share Posted April 26, 2011 I've not had one rebuilt but it should be easy for someone that does electric motors. Chevrolet called it Option C50 Rear window defogger. There's no heating element, so it's just a fan, not defroster. Dan Link to comment Share on other sites More sharing options...
montefrazer Posted May 12, 2011 Share Posted May 12, 2011 Have you tested the motor to be sure that's the problem? Might be a fuse, switch, connection or ground problem. "I think it must have been a "must have" option that served no practical function." It does work but it takes some time. It's not like a newer style with the heat lines in the glass. It is a defogger, not a defroster, even though it will eventually melt snow and ice off rear window. I have the same system in the 77 Caprice I drive year round. Much better than nothing if you drive in winter weather. It will clear up the middle of the rear window enough to see out. Link to comment Share on other sites More sharing options...
Roadkingronnie Posted December 2, 2011 Share Posted December 2, 2011 Take it out and spray a little WD40 on it then turn the fan by hand. Mine was just stuck. After some hand spinning, I connected the leads to a battery and it took off. Link to comment Share on other sites More sharing options...
