hello guys,
i have an update on my rear defogger/wiper situation.
1. i was at the shop and decided to take a look at the lgm. since i knew for a fact that the rear defogger was working at one point, i knew it was not the grid. and SO, at the shop we but the volt on the connectors at the grid and they didnt work...he put the volt on the wires (the left most black connector on the lgm from the pics in this thread) and after he "zaped" it with positive/negative check, the grid started defogging/working again when i pressed the rear defog button in the front. however, after opening the liftgate/glass a few times, stopped working (im not sure if opening the tailgate and glass is actually affecting anything at the lgm or the wiper module/motor). my license plate bulbs and keyfob lock unlock at the lift gate have never stopped working once. they have always worked perfect.
2. REAR WIPER... we really didnt check the wiper motor OR the white module sitting on top of it, only the lgm (and after the "zap" above, my wiper worked flawlessly for the same time my defogger worked). however here is the issue i have with it. intermittently it will stop working. when i have it to 1, 2 or 3 it works when it wants. sometimes it works all the time, sometimes it doesnt work at all. sometimes, ill have it on and it works for a bit and then "freezes" on the on position. i switch it to zero or off and wiper stays stuck as if it was on. THEN all of a sudden it will wipe how ever many times it would of wiped for the amount of time i had it turned on. its the oddest thing. also, whether the wiper reacts tot he 1, 2 or 3 position on the switch, it ALWAYS shoots water out i can see it on my rear view mirror.
**now, here is what i dont know if its causing an issue...my mode and what i beleive to be the defrost actuator, are bad. so the air is not circulating correctly. would excessive heat/cold cause the switch at my knee to not send the signal to the wiper? or send it late?
