Why windows lost sync....?
I would normally do the re-sync once I get home and back normal the window does. But then the next day I drive it is the same litany.
Any idea what is ghosting around?
And battery connection. You are dropping power someplace in the system or at the pse module.
Normal for 2-4 days, then the next day window goes only 1 inch then need to re-press then another inch. Need to resync then another 3 days trouble free. Anybody can help?
Read some threads that correct sync needs to press to detene 2 when window hits bottom; did this but didn't help. Only thing I didn't do is to sync all 4 windows but only driver's wide - I never touched the other 3 windows at all.

Window keeps needing sync every 3-4 days, otherwise the "express up/down" is dead or the window moves only 1 inch each time the button is pressed.

I am eagerly waiting for input from the gurus on this subject.

Dealer diagnosis: Possible that the CAN (controller area network) and the DCM (door control module) needs replacement, with estimates at USD7000.
1st Indy: the switch beneath the transmission lever is faulty. Needs changed. Question: is this switch 1 for 1 or 1 for 4 windows?
2nd Indy: the window track needs adjusted; if not then the motor needs replacement.
What do you think the most likely culprit?

I have had (to some extent) similar problem with my windows on the front. After battery re-connect, they would work fine, but after couple days the windows and everything electrical would stop working on the front sides (never back sides).
I brought it to the dealer and their diagnosis is DCM needs to be replaced. I went today to the recycle place to make sure that before I dish out 250 for each DCM I make sure that it is the problem. Well, we found out it is not. The guy ate recycle place told me that the central console controler for windows (or however the part is called) is more likely to be the problem as he sees them selling in ration 10:1 versus DCMs.
I took my apart and it seems that they are often covered by spilled drinks since it sits right underneath the drink holder (especially the mirror portion of the board).
I was hoping to completely take it apart, but got stuck on the mirror stick, which seems to be holding the board attached to the plastic casing. I did not want to brake the stick, so rather just cleaned what I was able to see with mineral spirit.
I will try to put it back later and see whether it would make difference. I was hoping to get the used board, but I have wagon and the boards are different from more common sedan versions which has trunk opener (which wagon does not have).
Anyway, I will report later and if anyone has an idea how to take apart completely the board, I would appreciate as I thought it may have some loose contacts or just needs cleaning.
Let me know how yours went.
