eman_be_lexin Posted October 12, 2005 Share Posted October 12, 2005 I am having a problem with my rear window defroster. For some reason it does not defrost the window at all. It used to but it doesn't anymore. I have had this problem for a while and have never done or said anything about it. I know the rear defroster and the outside mirrors are connected. The Mirrors de-frost/fog but the window doesn't do anything. Has anyone had this happen before? The rear window is tinted and has been ever since I bought the car 4 years ago.

steviej Posted October 13, 2005 Share Posted October 13, 2005 did you check the fuse? did you check the connections at the window with an ohm/volt meter? Quote Link to comment Share on other sites More sharing options...
anzial Posted October 13, 2005 Share Posted October 13, 2005 I have kinda similar problem - it takes forever to defog the rear window... Maybe it's just because I get too much condensation down here in SoCal Quote Link to comment Share on other sites More sharing options...
SKperformance Posted October 13, 2005 Share Posted October 13, 2005 They do use alot of power how is your alternator? Quote Link to comment Share on other sites More sharing options...
eman_be_lexin Posted October 13, 2005 Author Share Posted October 13, 2005 The alternator is good as of 3 months ago when I had my battery troubleshot for problems. They said something about checking the alternator and it was ok. I didn't check the fuse because I figured that if the mirrors defrost and the light comes on, then the fuse is fine. Where on the window do I check for voltage and what values am I looking for? Quote Link to comment Share on other sites More sharing options...
steviej Posted October 14, 2005 Share Posted October 14, 2005 I would start with the fuses. On my 02 ES, they are separate fuses. #44 is the outside rear view mirror heaters (10 amp) #64 is the rear window defogger (40 amp). steviej Quote Link to comment Share on other sites More sharing options...
91ls400 Posted October 14, 2005 Share Posted October 14, 2005 may sound stupid, but make sure the connectors are making a good clean connection to the rear window...i have seen them come off before! Quote Link to comment Share on other sites More sharing options...
eman_be_lexin Posted October 14, 2005 Author Share Posted October 14, 2005 Does anyone know how to get to the connection to the rear window? It looks like I have to remove the liner from the rear panel. Quote Link to comment Share on other sites More sharing options...
