Targa glass out...what is this?
Just took my Targa glass out yesterday, careful to maintain all 4 wires for the defroster. When I took the glass out, there are two black wires connected on one end...what is the other end?
I've fished around the side of the car and can't find anywhere I'd plug these. Any help would be appreciated - HELP!!!

I can't explain it, but there are 2 wires that power the heat, yet there are 4 in the rubber seal. 2 of these are jumpers and travel in the seal only.

They're just there for sake of being there? Not plugged into anything? Would it have any affect if i removed them when reinstalling the window?

If you look carefully the rear window defroster is actually two seperate grids. These wires connect the two. If you leave them out you will have NO defroster at all.

Then these wires actually connect the defrosters together? Meaning they connect to the window and to the window? (vs. on the car, or a harness i lost...).
KevinP73-I'll be using your method of reinstalling the Targa window...thanks for the input.

I will try - and yes removing them will affect your defrost. I rewired my 81 this fall
Some thoughts The drivers side is the Hot side; passenger is ground. And i think there are actually 3 sections of grids in the glass. Keep in mind the two stage defrost for targa glass - meaning only the center area of glass (and associated wire) are on when switch is pulled out or turned. The other two sections of the defrost grids (front most and rear most) are only powered when knob is turned to right. Take a close look at the defrost grids on glass and this will make sense. So -- on left side two hot wires come in - one goes to the center section of the defrost grid (the red/wht wire that has power when switch is in the pull or turned position) and one goes to the rear section of the grid (the red/blk wire that has power when switch is turned only) -- there is then a jumper wire in the seal from rear section to the front section so they get power together. I believe it is exact same arrangement on pass. side for the grounds. Thus 2 wires to each side but each side has a jumper connecting the rear section to the front. I think those rear connectors on the glass will have two male prongs/connectors to accommodate this. If your wires are not the colors above, trace them back to the area by the fuse panel in engine bay; easy to trace. I think the rationale for the above goes something like this. You pull the switch to all get the center section of the glass defogged quickly for driving so you can at least see out of it - you then turn knob to clear entire glass/defrost it. I have also heard you use the center section (switch pulled) only for defog, but the whole glass (switch turned) for defrost. good luck. Last edited by schoward; 12-23-2006 at 08:30 AM.. |

So there should be two ends for each black wire on the window. From a visual standpoint, connecting the window to the window, the reds & grounds I have marked, but the black wires have me stumped...

yes, the jumper wires should simply connect the rear section to the front section on both sides (driver and passenger), thus both ends of those wires connect to the glass.
The rear grid should have two prongs on each side (driver and passenger) The jumper wires mentioned above connect to one prong on each side. A power wire (red/blk) should also be connected to the drivers side rear and a ground on the pass side rear. If you do not have two prongs on both sides of the rear grid, they may have broken off. simply splice. remember the jumper wires simply 'jump' the power and ground from the rear most section to the front section. Center section operates independently. Looking at your picture above, the loose end of that black wire should connect to a prong just under the left side of that window sticker (front grid). It will run right past the prong for the center section and end at the front grid prong. same thing goes for pass. side. Last edited by schoward; 12-23-2006 at 07:24 PM.. |
