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 05, 2009 5:03 pm) -you should get resistance from the two terminals at the glass(a complete circut).. -next,see if you get any power at the window..then,check the ground side..(that's the one that always got me stuck!) --if the amber light isn't coming on-it could just be the amber light-if the switch checks out ? !..check and see if the amber light gets power,then check it's ground.. --electrical problems are some of the hardest things to diagnose,and with cars getting more complicated-it ain't gonna get any easier ! !-especially when we get-(shudder. ! )-electric cars! !..that's gonna be a LOT of fun! !

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!

Replying to: ryan99 (Oct 11, 2009 10:50 am) -fuses blow from a power surge..coulda been something got wet,and pop !..that's why they are there.. you have made my day !.. i helped someone figure out a problem,and a kinda complex one at that !...so,does the amber light work now? also,there is a timer on that circut,think it runs 15/20 minutes,to keep it from gettin too hot! was the fuse under the hood?-right or left side?,just to help the next person who runs into this problem! have a great day!
