Hello, I'm having a very confusing issue with my driver side window. It goes down but not up.
The drivers side window switches all work correctly EXCEPT for the driver window up command.
I downloaded the wiring diagram for the power window. You can see here. 2004_odyssey_wiring diagram.pdf
I checked the output of the switch. When I press UP on the driver's side switch, I can see 12 volts on the blk/wht wire A11 coming out of the switch. I can also see the voltage on the same wire going into the control unit at position 13 of the ECU.
However, when I press up on the switch, I do not see any voltage on the red/blue wire (ECU wire position 3) going from the ECU to the motor. I checked the continuity on that wire between the ECU output and the motor input, it checked out fine.
I bought a used replacement ECU to test it, and get the exact same results. Everything works fine, except the driver window UP.
I can't figure out why the control unit isn't putting out 12 volts to the motor when it receives the UP command from the switch. Is there some fault or condition that would allow the window to be commanded down but not up? Any advice is much appreciated.
