E89 Elec window fault

[T1zmiester]

Hi

Elec windows work on comfort entry and roof operation. Ie go up and down all 4. Passenger window works from switch up and down. However nothing works from the drivers master switch albeit the elec mirrors can still be controlled from the master switch.
Is there anyway of testing the switch with a multimeter to confirm continuity i.e. which pins carryout which functions.

I had the recall mod done under warranty regarding the positive battery lead behind the glovebox, problem only occurred after that, maybe coincidence

anyone help?

Hi, if your issue only started after the dealer had worked on it I’d be straight back-was it immediately afterwards or after a period of time?

It was after the dealer mod and I did contact them and they said bring it in, however it rectified itself so I didn't go back. They said that they couldn't see how the mod would have affected the elec windows and I must admit I tended to agree.
The Windows work fine when the roof is dropped so I know it's not the actuators
It's a control circuit problem I think and everything points to the master control panel in the drivers door. The part is expensive to buy so I wanted to run continuity checks on the old one first but don't know how the pins are configured to test whether the circuit makes and breaks when hitting a window button.

I had a problem with a bad connection on the plug to the drivers door switch. I dropped the drivers window and wouldn't go up. So tried all down and all got stuck down. Good job wasn't raining. Just before i had intermittent fault and was thumping door panel to make the switches work. Took door panel off, cleaned the contacts with contact spray, made sure plug was firmly connected, no problem since.
From memory i think one pin wasn't quite fully home in the socket.

My windows also played up after having the recall attended to back in May 2017. I contacted the dealer immediately I noticed a problem and they tried to reset all the settings, but to no avail. The next day they fitted a new ECU at their cost (with a new 3-year warranty) and all's been good ever since.
