Been trying to figure out my rear defrost. I found out after I ripped off the C pillar trim that the driver's side has been hit and repaired. Badly. The bodywork looks perfect on the outside, but the window frame itself is a mess (it looks like they hooked onto the C pillar to pull the body straight, and the trunk floor has ripples on that side.. nothing on Carfax of course).
Does power come in to the defrost grid on the passenger or driver's side on a 2007? The wire coming off of the driver's side (black or grey with yellow stripe) is cut a few inches into the plastic panel. Throwing a meter on the passenger side terminal and using the door latch (on the pillar) as a ground, with the defrost turned on, gives 0 volts, so if power comes in from that tab, there's no power. I've already checked fuses and swapped relays around with known good ones; the light in the switch does come on, and I hear a click somewhere in the dash when I try to turn it on.
The accident damage appears to be to the LR door and C pillar; reaching into the quarter panel from the trunk, everything feels smooth. Whoever did the body work (aside from paint) did a great job at hiding everything. :/
I did look several pages back, for what it's worth. I'll probably see if my library has a Mitchell book for the car soon; this is the only real issue I still have with it. The AC causes the back window to frost up on really humid days (look I'm a bit hot blooded okay, don't judge me for running it on max AC when it's only 90 outside!), it'd be nice to have the defrost working.
The pic makes it look like there may be a fusible link in the cut wire, but it's not doing much good if it's cut.
e: radio reception, with both the factory AM/FM radio, and my aftermarket Pioneer head unit, are good, so the antenna portion is working to some degree.
