KyleC Posted February 10, 2021 Report Share Posted February 10, 2021 Hello all, My Lupo has a problem where I cannot roll down the left window using the driver's side switch. It does work rolling up though, and the passenger side switch works both down and up. Is this just a faulty switch and if so, where can I buy a new one? Is it a hard job to replace? Thanks, Kyle Quote Link to comment Share on other sites More sharing options...
ObjectiveAway Posted February 10, 2021 Report Share Posted February 10, 2021 I think its wires fault not the switch, cars in 90ties had very direct wiring from body to doors, therefore wires wraps a lot every time you open and close your door. Its works fine for years, but it is very common electric fault reason at doors or even rear door. Quote Link to comment Share on other sites More sharing options...
Skajme Posted February 11, 2021 Report Share Posted February 11, 2021 (edited) It's probably the switch, yeah. Them dying is pretty common. You can confirm it by swapping the switches over and seeing if the problem moves with them. It's pretty simple to do, you just need to remove the door card to get to the connectors, it's all fairly obvious once you're in there Edited February 11, 2021 by Skajme Quote Link to comment Share on other sites More sharing options...

KyleC Posted February 11, 2021 Author Report Share Posted February 11, 2021 Thanks all for the advice - I'll take the card off over the weekend and make sure the wiring is fine. I'll also swap over the switches and see if that makes any odds. Quote Link to comment Share on other sites More sharing options...

Skezza Posted February 14, 2021 Report Share Posted February 14, 2021 If you have any similar issues with your new switch it'll be more likely the wiring in the boot between the door and car. Not a fun job. Quote Link to comment Share on other sites More sharing options...
Red Devil Posted May 28, 2022 Report Share Posted May 28, 2022 Hi. looking for ideas regarding passengers window problem. the window works perfect from drivers side switch up and down. from the passenger side switch, it will only go down !! IT IS NOT THE SWITCH ! has been like it for a while and would just like to clear it up it does exactly the same when applying a wire across the wiring loom terminals. Could it be the motor? Does anyone have a wiring diagram for the window switches/ motor termination plug thanks in advance. Quote Link to comment Share on other sites More sharing options...

Therefore its eiter switch or wiring fault. It is easy to test that in multiple ways, by attaching other wires from another electricity source or with multimeter.
