Hi,We have the above with neither front windows working the customer says when they first packed up he pulled the 5 amp fuse number 28 in the lower fuse box in the centre dash panel fuse looked OK put it back and the windows worked again briefly.
I have checked fuse seemed OK but replaced anyway. I have done a global scan VCDS and no fault codes. In block codes it says windows not installed. Unit is coded which doesnt seem right for this van with central locking, electric windows,nsr door,But how would it get the wrong code in it if it worked before. I am presuming I know its dodgy to do so that if the module doesnt think the windows are fitted that I wont get any comms with the door control modules. I have tried the extended press of the unlock button on the key not sure if this works on a T5 but neither window dropped.
Am I right in thinking that if the drivers door module is faulty ,that neither window will work as thats where I thought i would start testing tomorrow. Posted Thursday, December 12, PM. Forum Master Technician. Thanks for your reply. Its an old shape ,the passenger side switch doesnt work either.

Many of these are cable actuated and this will eventually break the cable. I had to replace two on a Chevy Silverado. The replacement window operators are cheap enough but I learned my lesson after the second one.
