Intermittent fault

Check the connectors for the control module and power window lift motor. Check for contact resistance and oxidation. Check for loose connections.

Check the cable between control module terminal #24A and power window lift motor terminal #5. Check for a short-circuit to ground. Check for a short-circuit to supply voltage. Check for an open circuit.

When raising or lowering the window, the voltage between power window lift motor terminal #5 and ground must be 2.4 V.
