98 lesabre rear defrost not working.

Post by rogers9c1 »

Hey guys the last few days we have gotten some light dusting of snow in southern Ontario, and I have just realized that my rear defrost is no longer melting the snow or defogging my window.
I do have my rear window tinted but it has been working fine for over and year with the tint, What are some of the first steps of fixing this problem? thanks and much appreciated!

well I found the problem I think, checked the fuses and both underhood and under dash ones were good, then removed the rear sail panles only to find a black melted box with melted connectors going to it for the am radio, will post pictures later tonight.

in the buick, the rear windows defogger power does indeed go through the radio antenna module. the purple wire is the power wire going into the module. there is also a relay in the rh ip fuse box, relay G.
