hey everyone i got a 1990 4 runner and my rear defog is working really bad what can i do?

 

mine is aweful too

 

Mine works like crapola too. I have taken the back access panel off and cleaned the contacts. That helped a bit

 

Any more ideas for making it work better?

 

A chronic problem. Keeping the inside of the glass clean will help reduce the workload on the defroster. Dirt absorbs moisture and will defog the window faster. Not much to do on the outside other than have a good ice scrapper.

 

should i change my whole back window in order for it to work beeter?

 

i just figured it out. The wires for the defog were disconected so now it works. Finally.
