Looking at 98' 300, both windows/mirrors don't work. Actuators+switch, or worse?
Hi,
I'm looking at a 98' 300 to buy, Both windows don't go up and down and electric mirrors don't work.
I know the actuators go on these cars, but I have never seen both go at the same time along with the mirrors.. The seller says something was spilled on the switches but I think it is another problem as the both don't work and the power mirrors are out as well. It could just be both actuators, but that seems unlikely with the mirrors out as well. What do the switches connect to? Is there an ECU that could be bad or have shorted out? What are the possibilities of what is broken/shorted?
What is the absolute worst case scenario?
Thanks

I would guess wiring, Have you ever taken a door panel off and looked at how it all connects? It's pretty easy to pop the window/lock switches out (although, my pass. side switch was @#$! hot glued in place) to look inside and see if it's something as simple as someone worked on it previously and forgot to plug them back in.
Do the power locks work from the driver's switch?

Mirrors have an ECU that is apparently a nightmare to replace due to it's position behind the dash. Very hard spot to get to, might be easier to dislocate harness, and mount new/used ecu in new location under dash, and leave the old one where it is provided you can even disconnect it without removing too many other items. I believe Raine's thread had pictures/tutorial.

I would check the wiring between the door and the cabin. The wires get cut with age when you open and close the door. My passenger window didn't work for the longest time, and when I pulled that harness out I noticed the wire was cut and a few others were damaged.
