Each window motor is protected by a built-in circuit breaker. When the
switch is held on too long with a window obstructed, the CB will Open
the circuit and will reset automatically as it cools.
The reversible motors are controlled by two normally-closed and grounded
switches. SO.... there is a Hot circuit at each motor when the key is
On or Acc position. The Up/Down sw is controlling the reversible
grounds in the motor. Usually what goes wrong is a faulty switch.
Corrosion/dirt causes a failure at the little brass contacts to make
good contact. Cleaning the contacts is not an option, although I
tried....to no avail. Replacement of the MSA(master sw assembly) or the
individual sw is needed.
If you are 'electrically inclined' I can email the diagnostic tree.
