my rear defrost doesnt work. i will press the buttoand it wont stay down. if the ignition is in the On or accessories position the light will come on, but not if the car is running. the button won't stay down thow. i ordered another button of of ebay and still the same thing. is it a fuse or something. i checked the wire connetions on the support cylinders and they are good. the lines on the windows are in perfect condition from what i can tell and their isn't any seperations. please help it is cold in the morninig and scrapin that big window gets to be a pain when its that cold out and all you want to do is to get in the car.

 

It could be the defoger timmer. Here's a link to where you can check the wiring. http://www.geocities.com/vtcamaro/Wire-Diagrams.html

good luck

 

this is kinda off topic, but if u put a towel over the window before u goto bed at night, all u have to do it take it off and that should save u from having to scrape it every morn till u get it fixed. this also great for frost and snow.
