So I guess the electrical possessed sprirt of my E320, had decided to leave the passenger front window and jump to the passenger rear instead. Now my front works great
Although my rear now wont go back up
Yippie.
Given this random "feature" and a clicking convenience relaym, I also noticed that the original CCM also had the windows powered with the ignition off key out
I went to the pick-u-pull and got another CCM cheap, has a warranty swapped the two and. My windows do not have power with the key off, the convenience relay has also stopped clicking (proly the windows being hot) yet no difference with the RR window operation. The Parts unit was from a sedan, from what I read they are all supposedly interchangeable between the w124s and several W202 hence the 202 part numbers.
I used to be able to get around the issue with the all up/down feature from the convertible top switch and or the door lock, but neither of those functions work now on either CCM.
When running through the window switches I can hear all of the relays in the CCM click up/down except the right rear which only clicks down, but not up.
I had opened and looked at the parts yard CCM before installing it and it looked pristine, no signs of burning or corrosion. Now that that CCM is in the car, I also opened the original unit and guess what... looks fing pristine
Any ideas of how to test the unit or how I can restore use of my rear window?
