Rear Defroster problems???

Post by j_villines »

My rear defroster will not work the light on the button on the dash doesn't light up and the back defroster does nothing. Is there a fuse or maybe a place I can check for a wire loose or disconected. It makes it a real pain to drive when it is rainy. Any help would be appreciative!

Look at the rightside engine compartment.Inside the fusebox,you'll see 5 big fuses.Look at the 2nd to last one,its a 40Amp fuse.If its good then check your rear defog relay,if thats good,then check if you have voltage at the defog grid.

I checked the fuses and as far as I can see they are still good I will test and see if they have power to them later and get back to you guys that are helping me get through this annoying problem. Later
