The unit just quit working. None of the control buttons light up nor do the indicator light. None of the buttons work when depressed. I remover the door panel, found the interlock switch and replaced it. No help. The only two devices that seem to be a possable problem is the encussion panel(touch panel) or the module control assy. The problem is that I do not have any wiring dia. I do know that all the voltages going into the module are there and that the inter lock switch works. I can't read anything from the output connector for the ribbon cable. This may not mean anything. Now because the touch panel does not work at all i'm thinking that the module control assy is the fault.
What do you think? Is there a way to get the wiring dia.?

Thank you,

BT
