My power windows are giving problems. It started after I removed the interior door panels to add sound deadening, so I can only blame myself. IMO the electrical plugs for the master power window switch and the power door locks are too fragile. The metal male/female connectors inside the plugs are made of soft metal (aluminum, maybe?) and they can't withstand multiple unplugging and re-installation cycles.

I know, I know. I shouldn't be unplugging the connectors too often but it an effort to make the windows operate correctly....

So, sometimes 3 of the power windows work but more often they don't. The driver's side rear window never works. My guess is the problem lies in the driver's door master switch. I think the connections should be tighter but I don't know how to do it. The tiny male/female connectors are impossible to pinch with pliers.

Would dielectric grease help? Should I try to bend the male pins ever so slightly to create more friction against the female connector?.. that could be risky. Any ideas?

The crimp contacts on most of these connectors is made from tin plated brass. They are typically good for a few dozen cycles.

Dielectric grease is actually an insulator. It helps only to prevent corrosion due to moisture.

I would try to bend the pins slightly to make more solid contact. Also make sure none of the wires have pulled out of their crimp contacts. If you break a pin, you can find them on Digikey and Mouser. Look for ".070 MULTILOCK" This is used on most the larger connectors on Subaru.

Solved

Finally removed the driver's door panel today to check the wiring and the master switch. Turns out that one of the wiring pins was not pushed down enough to make contact. Using a very small flat head screw driver I pushed the pin further down into the female connector on the bottom side of the master switch and immediately found joy.

Hallelujah!! :thumbsup::thumbsup:
