At the moment, I'm just talking about the front passenger side window. On the hinge side of passenger door, should be wiring harness, probably has protective covering, pull the covering back to expose wire colors. Note the wire colors for battery and ground. Battery is voltage, use a test light, check both orange wires for voltage. You can use to testlight also to check ground, check both grounds. With test light connected to battery voltage, probe the ground wire, both of them, if the lite comes on, at least the ground is good enough to turn on the test light.
