DDM or Not?
 

I just want to get this straight, so i get an idea where to go and what to do...

My driver window works intermittently, most often not. Seat memory only serves to have the car beep at me. If i try using the driver power door lock, they will unlock, but then she beeps at me and they won't do anything else. I can control the pax window fully. I can also control the mirrors fully. The all-door window lock no longer lights (i therefore assume it doesn't function), but it's hard to tell since i cannot control either rear window anyway, at this point from the driver door AND the individual doors. And they have failed progressively, like one at a time. Although the driver window has pretty much stayed the way it is for awhile now. From time to time it recovers normal functionality. The key fob locks and unlocks the car, but has now begun to not unlock the rear doors. Some times it causes the car to react like the button has been pressed twice rapidly (either lock x2 or lock/unlock). This also causes her to beep at me.

That's about has detailed has i can get, and that is every description that i can think of at this time. I'm going to do some work on her this weekend; i just want to know ahead of time what this could be. Is is the DDM? Corroded terminals/switches? Or both? Should i even bother asking and just "rip" some stuff out (like seats, carpet, moldings) and fix and clean as i see fit? I have now gotten to the point where i need to fix it since the failing of the last rear window switch has left it stuck down (luckily only about an inch or two, under my ventvisor) and it needs to go back up soon so i can wash her. Or failing that, before winter arrives here in WI (which could be tomorrow here, you never can tell).

Sounds like the DDM is bad but I would check the power and grounds to it. Might be able to find a good used one in a wrecking yard to save some money.
