Right front window problem
For a 98 Camry - the right front window doesn't work. I applied 12v to it, and the motor works. I also tested the continuity on the switch, so the Green/white and Red/blue wires (coming from the driver's switch, right?) are getting current, but the Green and Red wires are not getting current. The blue wire also lights up. So is this a switch problem more that a wiring problem coming from the driver's side?

The following might help with diagnostics.
The drivers switch operates the motor by reversing the polarity of the Grn/White and R/Blue wires. One wire is energized positive while the other wire acts as the ground return wire to the drivers/master switch. Here the individual door switches act as a pass thru from the drivers switch to the R and G motor wires.
When the drivers door switch is off, both G/W and R/B wires are grounded to chassis via a ground connection at the master switch. Confirm this is true. When the drivers door switch is moved to UP is G/W is positive and R/B is negative and visa versa for down.
The individual door switches operate by taking power from the blue wire then directing it to either the green or red wire of the motor. The individual door switch then.routes the circuit return wire (negative polarity) to either the G/W or R/B wire depending on the UP/Down position of the switch.
Here if UP is selected, power (positive) goes from the blue wire to the green motor wire then to the red wire to the individual switch. The switch then connects this wire to the R/B wire going to the driver switch (having both wires grounded when off) to complete the circuit.
When DOWN is selected power goes from the blue wire to the red motor wire then to green wire to the switch. The switch then connects this to the G/W wire to complete the circuit.
Is positive power making it through the switch to the motor. Select up or down at the drivers switch and check for the same power at the motor wiring. UP is R/B powered, down is G/W.
