Screen shows picture only on left 1/2 - right side has raster and a gray dull motion ( no image) same with or without a dvd disc inserted. Power by 110 V or battery pack makes no difference Unit has not been in water or excess heat or cold. S/N:ta290ed161660 No attempt to repair or disasemble as yet Thanks

Here is a schematic which my dad & I devised over the course of two hours for the power mirror wiring on our 1992 lesabre, as we couldn't find any wiring info to handle this issue.

That's our/my website, and that folder will let you see & get all of the pictures & diagrams

The wiring harness for the power mirror switch was acquired through Rock Auto, and the wire lettering scheme was embossed onto the plastic.
Here's a written breakout of the wires & their locations/purposes.

A= Ground
B= Common Left/Right Motion(Splits to both sides)
C= Common Up/Down Motion(Splits to both sides)
D= Left Side - Left/Right Motion
E= Left Side - Up/Down Motion
F= Right Side - Up/Down Motion
G= Right Side - Left/Right Motion
H= Positive 12V

Now Assuming that all of the power mirrors are wired & color coordinated the same, that would connect....
B -- Light Blue wire of Both Mirrors
C -- Green wire of Both Mirrors
D -- Gray wire of Drivers Side Mirror
E -- Dark Blue wire of Drivers Side Mirror
F -- Dark Blue wire of Passengers Side Mirror
G -- Gray wire of Passengers Side Mirror

In our circumstance we hooked up the power and ground inline with the power window Power(Pink) & Ground(Black) wires which are nearby in the door. The fuse/circuit should easily handle the minor load of power mirrors, even if you were using the windows and mirrors at the very same time... a rarity I do suppose.
