My electric windows packed it a while back then started working again. then after heavy rain packed in again.

 

Figured it was just water ingress in the controler. have stripped the door card off and removed the motor and its spotless not a mark on any of the connectors. 

 

Have run a voltmeter across its pins

 

its getting 12v+ to the controler and the window switches themselves are getting 12v+ power too. 

 

Theres no power being delivered to the motor when i press the window switch and use a multimeter on the motor supply pins

 

The passenger window works manually for about 5 minutes if i unplug its door loom for a few seconds the plug it back in.

 

 

ive probably answered my own question and its the drivers controller that is dead but is there anything else i can check.

Repaired a few wires in the door jam to repair the door lock but the rest of the wires seem fine in both drivers and passenger side doors.

 

 

 

Thanks in advance for any help.

I'd be checking the wiring loom from door to A post. 

 

Edit sorry just re-read and realise you have.

Update. Borrowed a motor module from a fabia. Unfortunately the fabia has 3 connector ports and only one of the cables for the roomster fit leaving the 2 pin plug unplugged. Tried the windows anyway but nothing. Put the old module back in and now the windows suddenly work. Got me completely puzzled.

The drivers window works on automatic unless i let it go all the way down then it will only work manually untill i reset it. Wondering if the thermal overload could ve playing a part in the windows failing?.

Is it possible the power supply is intermittent due to broken wires?

So after chasing all the wires from the door running continuity checks everything is receiving power as it should.

 

started looking into if it could be the thermal overload in the drivers door.  if i leave the window down 2mm from fully closed it stays working all the time. if i let it fully close and lock the car up then unlock it the windows pack in for a while.  so looks to be the thermal overload tripping all the windows out. would this be caused by the motor and controler or would it be an issue with the window regulator itself ?
