Very Intermittent pass. window working, short?


My 1997 Alfa Spider LHS electric window seems very intermittent. I have replaced the window regulator as intially thought the window didn't work at all. It rarely works, but when it does it works a few times, without a problem at all. But most of the time it doesn't work whether from the switch on the driver or passenger door.

Strange thing is, instead of working, sometimes the light in the window switch goes out when pressed on the other door, or the locking sounds like it's going and even recently the interior light goes out when pressing the window button. This happens only when the window doesn't work.

Could this be a problem with the switches or relay or does it need much greater investigation into the wiring loom. A starting point to eliminate some obvious bits would be great help!

I only have one electrical gremlin being this one, and it stops the full open air experience!

I would check the connections to the switches first, they could have some corrosion and then the relays and any earth connections. Good luck.

I would take the window mech out and have a close look at soldered connections ontop of motor, often the solder cracks on P1's over the years. If you do find this is problem, just desolder and then resolder. One other issue i have found is that water often ends up actually inside motor and this is a nasty job to sort as you need to pull motor apart, dry, clean and grease.
