Car Forum / Volvo Cars / March 2007Rear window heater
I have a 87 940GL wagon and the rear window heater has quit. I think the fuse is #21 and it and the other fuses check good. The light on the switch does not come on. So, if the fuse is good, where do I look? ED > I have a 87 940GL wagon and the rear window heater has quit. I think the > fuse is #21 and it and the other fuses check good.

Oh come on, cut the poor guy some slack. Even a knuckle dragging moron can tell if the rear window defroster is worker, especially in the winter. Duh. Ed, check it with a test light when it is "On." Touch the prod first at the place where the wire attaches to the grid: if it lights up, you have power to there, and a break in the grid. Keep testing until you find the break, then repair it with the inexpensive repair kits sold for that exact purpose at car parts stores. Or.... perhaps your wiring harness has (finally) frayed/cracked where it crosses into the tailgate within the hinges... Same thing happened in my 1990 245 .... the ipd site is very helpful.... as are the instructions included in the package!! Replaced both sides in mine in less than 2hr..... which included taking the tailgate completely off! http://www.ipdusa.com/ProductsCat.aspx?CategoryID=110&NodeID=865&RootID=629 Hope this helps, Kevin >> Are you sure the window heater doesn't work, or could it be just that >> the lightbulb in the switch has burned out?

I cant find the fuse number in my owners panel and there is no mention of where the relay is located. My service manual refers to the relay but does not show where it is located. Thanks for the suggestions. In another month it wont matter. >I have a 87 940GL wagon and the rear window heater has quit. I think the >fuse is #21 and it and the other fuses check good.

I'm not sure a bad relay would keep the lamp in the switch from coming on. |
