This is a bizarre fault. I used the car this morning and the windows were working fine. I've just picked my children up from school and none of the windows are working, front or rear. The electric sunroof is working fine. Has anyone had this issue before? Not sure where to look. There is nothing on the fuse board for windows. Thanks, Paul
I've found on internet number 24 relay is supposed to be thermal fuse (20A) – power windows. Haynes manual is saying relay 6 is thermal fuse for electric windows.
There's a 20 amp thermal fuse 'above the relay plate' apparently. May be worth checking that hasn't somehow gone permanently open-circuit. Some photos of one in this thread, I doubt they changed between mk2 and mk3: Thermal fuse for electric windows | Club GTI
Thanks Pete. I’ve found this…. https://www.heritagepartscentre.com/uk/443937105a-thermal-fuse-30-amp.html No idea where that goes on relay board though.
Also, according to Haynes (I know they aren’t reliable) it’s relay 6 (top right of diagram). When I look at my fuse board, the top right relay is 191 and looks nothing like the above thermal fuse.
Have a look at the image in this listing, and the location of the thermal fuse: VW Golf Mk3 16v Fuse Box GTi 96 Relays | eBay (Just above relay position 5)
Aha! Brilliant Pete. I tried taking a photo of relays but was too tight to get phone up there. I know where to look now when replacing the thermal fuse so will order one now. Cheers.
It doesn’t seem to be in the same location on my fuse board. Not sure if I can just see the edge of it above the white relay?
thats the thermal fuse yep. have you also checked the main fuses, one of them is the ignition live which triggers the windows. to test if thermal fuse is ok test the total closure from the door lock, hold the key 'unlocked' windows should roll down, and 'locked' windows should roll up
fuse 14 for electric windows plus a few other things, reverse lights for one. check the wiring to the switch and switch itself (or just check if reverse lights work I guess )
Hi Johnny, I’ve got rear door handles on the front of car so can’t do that test. I opened sunroof and then pressed close on alarm key fob and the sunroof closed via total closure. Does that mean it’s not the thermal fuse?
sunroof has its own fuses, just swap the thermal fuse with a standard fuse for now and try a window, if it works then its the fuse if not its some other issue
I will check these fuses after I’ve got children from school. Will lost back here with result. Cheers.
Johnny!!!!!!! I am at the virtual bar buying you a pint right now! It was fuse 14. All windows working again. Many thanks for everyone’s advice and help. Paul
