Hello, because you can bump the driver side window switch and make it work, then you have a loose pin in the driver's door switch. It's the only place power comes from for the Pass side window. The pins in any connector loosen up over time, over the years of use, the pins get a little hot with current flow, then they cool down, and then again, and over. Eventually there gets to be a pin that's loose enough that it causes resistance in that connector, which causes more heat. And the problem just gets worse. On connectors we suspect a loose pin, we do a pin-drag test, to see how tight it is, but I think you'll find that if you take the switch out and can tighten up the female end of the connector, you'll solve the issue. It can be any one of about three pins that could be loose. Pin fitment issues can cause all kinds of very difficult problems especially when its computer related. Sometimes we use thermal imagers to find connectors that are hot. Works great. Below is an example.
