603 - electric windows

[Peter Hoskin]

I found the drivers switch for the passengers window stuck in the up position and the window was firmly closed and would not respond to either control switch. The drivers window operated normally. I changed the drivers 2 switches over so the previously stuck switch now operated the drivers window which it did so correctly. ie fault not in that switch.
I tested the window winder motor by direct connection from the battery and it operated the window up and down correctly. ie motor not the problem.
I removed the two Circuit Breakers, they appear to be sealed units, I assume they are overload devices that work on excess current (what Value?) and auto reset. Neither was in an open circuit state so I assume OK?
I have followed the wiring diagram and colour coding shown in the expanded diagram by a Mr C R Foster dated 17/09/99, which I checked against the more difficult diagram in the Drivers Handbook.
I am getting 12+ volts at both switches.
Any suggestions as to what I do next
