| Hi All, I am looking for a little advice with my rear window defogger. I have a 99 Cherokee limited with heated mirrors and my rear defogger quit on me. I am trying to fix it myself but like most people my time is limited. So far I have found that the switch is good (tried a different one,) the relay is good and there is power to the switch (checked with a multi meter) The fuses are also intact. I can hear the relay click on and off when i press the switch, but no amber indicator lamp and no warmth on the glass. Today I checked the wires at the hatch and didn't see any broken wires and also the drivers mirror. Does anybody know of any common fail items for this or common short circuit spots? I have a repair manual that explains how to test the instrument panel with a multi meter and that is the next step unless anyone has any advice. Thanks, Ryan | |

Replying to: ryan99 (Oct 05, 2009 5:05 pm) Other than that, I'd start chasing wires after confirming the switch is good and you do not have power at the rear grid (one lead to the wire coming into the grid; the other one to ground. If the switch is good, the likely culprit is where the wire goes into the hatch from the body itself. |

Replying to: ryan99 (Oct 10, 2009 5:00 pm) --if you can dig up a L-O-N-G- TEST LEAD,TRY PUTTING STRAIGHT POWER TO THE GLASS-ON THE POSITIVE SIDE....(MAYBE THEN YOUR AMBER LIGHT WILL LIGHT?)--sorry-caps lock stuck.. --all this sounds like you've got a bad relay..unplug the relay,and with the test wire,unplug it from the glass-gently,-then,go back to where the relay plugs in,and see if there is power at the "output" point,if not,wire is broken somewhere..i have run a extra wire-tucking it in,so it doesn't look bad-just to save trying to trace where a broken wire is.. --have you tried replacing the relay??--if you hear it "clicking",have someone turn it on and off,while you trace it by ear ! ?.. --no power at the glass means a bad relay usually..try the simpler things first,then go for the more complicated..after all,it's just a 12v circut-but it pulls a pretty heavy load.. --if you get it working,and find a few bars in the grid that aren't heating-they sell a conductive-copper colored paint-used to repair defrosters.. best of luck! |

Replying to: ryan99 (Oct 10, 2009 5:00 pm) -the relay has TWO sourses of power..one to activate the coil(the clicking noise),then-and where your problem may be-is a thirty-to-fifty amp fuse that would put power to the window..check owners manual,or the fuse diagram-grouped with things like the heavy fuse for the a/c,and see if that's the trouble..it just might be ! lots of luck!
