Left rear door, window and lock not working.
2009 MB E350 W211, left rear door, window and lock not working,
I've removed drivers door module, replaced with same from Ebay, no luck, installed old one,
rear door, removed boot to door and jamb, no obvious wires broken,, tested power coming into module,, 11.47 volts, steady, tested leads to control switches, volts move from 9, to 9.18, 9.23, then 9 again, ( while power is plugged in )
pulling module next, and replacing left rear door module.
With module plugged in, SRS, flashes, AC goes on and off, battery drains over night,, replaced battery 1st, 8 months ago,, license plate light blinks slowly, turn signals very slow,,
right fog lamp blinks, windows roll down, then stop, same as up. All other windows and locks work, seats, heated seats, etc.
9 months ago, pulled in driveway with drivers window down,, didn't realize this,, then it rained all night,
drivers seat and floor where both drenched.
left rear door window was closed while it rained, im at a loss.
Any help or knowledge would be greatly appreciated.
Removed the DCM, replaced it with ebay, tested DCM, same symptoms, reinstalled old DCM, ( drivers door only )
removed Left rear DCM, have not opened it to look for corrosion, I will do that right now,, cross your fingers..
Could it still be the drivers door control module?
Removed left rear DCM, opened up, no corrosion,
only plugged power back in to DCM, problems with blinking lights, ac going on and off, SRS, light on, all same issues, with only power going into it,, could it be defective?
