2003 V70, 2.4NA, 225,000 miles:

I've got a weird issue with my drivers window freezing in any position it was last moved to, but only when the engine is running. If the key is in position I ACC or position II IGN, I can open and close the window all day long (as long as the engine isn't running when the key is in position II). I can even move the window when the key is turned OFF, as it should - you know how you can roll the window up for some period of time after shutting the key off. The problem also affects the mirror control and door locking. But only the drivers door window and lock are affected - the other three doors' windows and locks will move, even when in failure mode, regardless of whether they're being controlled from the drivers or passengers door .

This began about a month ago as a very intermittent thing, but now I can count on it not working. At best, I might get about three opportunities to move the window after the engine is started, then it will freeze. If the engine is running and the window is frozen, I can hold down on the switch with one hand and then turn the key back toward position I just enough to interrupt the ignition for a split second and then back to position II, sometimes quick enough to keep the engine running. That quick interruption in ignition allows the window to start moving. It never freezes in mid stroke as long as I keep holding the switch. Once I release the switch, regardless of window position, it will most likely be frozen in that position the next time I try to move it.

So far I've taken the DDM apart and lightly cleaned the contacts. I've disconnected, spray cleaned, and reconnected the following disconnects - 1 at window motor, two at the DDM, 1 at the door jamb. I left the tweeter wire alone. No change it behavior after all the cleaning. I'm kinda spooked by all this as I fear the problem may be ship side, given that an interruption in ignition wakes everything back up.

Also, would a VIDA/DICE setup be much help in these situations? I've resisted getting into all that - well so far have never really needed to. I guess if we're going to keep (affordably) driving these things I'm going to have to get into that stuff. Two P2's in the household.

Any suggestions as to the most logical step forward with this problem are greatly appreciated.
