I can't see out of my back window too well. Only if I put my front defroster on high it will clear.

i get in car at store front and back window wnt defrost i sit and mess w defrost and air conditioner and nothn after 10 mins it finally starts defrosting

The rear windshield defogger has failed again. I had this fxed 2 times already and is going back in this week.

Ok so we bought the car new in 2004, last year the heater started acting crazy would only work if you slammed the door. Now you have to tap under the dash on the passenger side to get it to come on. Now my rear defrost will not work at all, the light comes on & says it's on but it sure doesn't work. Ugh I hate Chevy.
