Hello all, new member here so thank you for having me.
I recently bought a mk1 2003 Seat Cupra R. It’s been lightly modified by a previous owner (someone before the owner that I purchased it from).
My issue: None of my windows work from the switches, (front and rear, both being electric). The windows go up and down when the lock and unlock button is held down on the key fob, so I know that it’s not a motor issue. I have tested the wiring from where it enters the chassis at the base of the A pillar and at the door where it connects to the motor and master switch. All the wires are showing perfect continuity and constant and switch live where it should be. This made me think that it was an issue with the comfort control module. I’ve also bought a new master switch for the drivers door and having the same issue.
I plugged in to VCDS and had the error message “cannot connect to module.”. So I bought another CCM, installed that with the battery disconnected, reconnected the battery and I get the same error in VCDS.
I took my multimeter to the brown plug that connects to the CCM, I’ve got constant live but no switch live to the black wire.
Am I checking the correct wire for switch live?
Has anybody else had a similar problem?
Could anyone shed any light on this?
I noticed that some of the wiring looks “non standard” as there is an aftermarket lighting module behind here and the headlight controls have been updated to a newer vag switch with auto lights.
I appreciate anyone that reads through this as I understand it’s a bit of an essay and a bit of a head scratcher (for me it is anyway)
