My electric windows work fine in my mk2 golf as long as I don't drive anywhere. As soon as I pull away they blow the fuse. Any ideas anyone?!

Put a bigger fuse in :D

its a quick fix, but not really the solution lol
sorry have no idea when it comes to electrics

Do they work when the engine is running at idle? I find it a little strange that you would blow a fuse as soon as the revs pick up.
Check the wiring as it goes from the car to the door. You may find a stripped cable there. If that earths out against the body, the fuse will blow. Then check all the wiring within the door for the same defect.
Further investigation: Remove the electrics switches one by one and try as you go to see if you blow any more fuses. Could be a dodgy rocker switch. You're going to need a few fuses to sort this one out me thinks. :sad: :undecided:

They work even if I rev the engine up as long as I dson't move the car. I've already thought it might have been the switches, I've taken them out and the fuse still blows.
Would the wire going to the doors be live without using the switches?

Not sure without looking at the wiring diagrams. Switches normally work by closing the earth return so I guess that yes, there would be power. As soon as the car moves, something is disturbed and moves causing a short. Usually these faults are intermettent. Unusual to find it happens all the time.
Try starting the car again and moving the doors open and closed to see if the fuse blows again. Also, see if the fuse is a shared one. ie, protects another circuit such as some kind of lights. The problem may not rest with the windows, but with something else that shares the fuse. :wink:

Change them for mechanical jobbies, no more blown fuses !! :grin: :grin:
and then sell the kit to me for a tenner !! :laugh: :laugh:

The wires to the doors are only live when the switch is pressed, I just tested the wires coming out of the switches and they only become live when the switches are pressed. The fuse is shared with the heated washer nozzles, I disconnected the wires from the nozzles and the fuse didn't blow as quick so I think maybe something to do with that circuit as I moved the wires about a bit when I unpluged them. Didn't blow the fuse when I moved the doors, only seems to blow when the car is moving. I've checked that the peddles aren't catching any wires, you never know.

Just check the clutch lever under the bonnet is not catching on a loom. Apart from that, its just a case of keep investigating.

Check the earthing leads from engine to chassis. I had a badly corroded lead and the result was that the fuse for full beam headlights kept blowing. Now its been changed I have had no problems and the lights are much brighter.
