Electric Window Switch
A minor victory today over the Alfa's electrics!
My passenger window would raise using the driver's side switch but not go down. I popped the switch from the door handle and checked current with a multi-meter on the wires, all seemed well. Then I took the switch mechanism out and looked at the contacts which worked fine. However, the "down" contact looked a bit burnt so I gave the contact a scrape with a sharp tool.
Switch reassembled and now working fine in both directions.
