Broken window on driver's side - 5.0L griff

[miller1899]

Evening

How do I fix my window? It stopped working a while back and a specialist supposedly fixed it but it is now broken again. There is no sound of a motor straining away or anything like that and it appears to be completely dead. Is it easy to pull the window switches out? Thinking back to the last time it broke, sometimes it seemed to make a difference if I pressed down more firmly on the switch, which makes me think that it could a loose wire rather than a broken winder/regulator thing.

Any tips gratefully received.

I assume the passenger side window is working okay, so it's sadly not going to be anything as simple as the fuse. The window switch will lift out of the panel, but be careful not to damage the veneer. If you have a digital multi-meter you can check the continuity of the switch and connections. If they seem to be okay, the next thing would be to take the speaker out of the door and you should have reasonable access to the window motor connection. It's not uncommon for the connections in the door to become corroded over time because of water ingress. Again, if you have a DMM you should be able to check for power to the window motor.

Firstly swap the switches around and if that doesn't work play with the bundle of wires that run between the body and door whilst depressing the switch,these often get partly or fully pinched.check these out fully before you start pulling the door apart.taking the speaker out will give you access to the motor connectors

if its not the switch try this.

i have had window failures on all 3 of my tvr's. in each case it has been the wiring connector block that sits inside the door. its poor design (no surprise there then) and basically the block sits in the base of the door in a small pool of water when it rains and the connections corrode and fail.

take off the inner door panel and it is easy to get at the block, clean it up and grease it - finally i cable tie it to the motor to keep it off the bottom of the door and put a small piece of clear flexible plastic over it to stop water dripping on it.

Thanks very much indeed. I've ordered a multimeter from Amazon and will have a go. Thinking about it, the speaker in the right hand door has seen better days and have been pushed in a bit. I'll let you know how I get on.
