2002 Acura RL - Passenger front window

Asked by Nov 19, 2016 at 12:13 PM about the 2002 Acura RL 3.5L

Question type: Maintenance & Repair

Installed a new front passenger window regulator which works when I apply
power to the motor (alligator cables and a spare battery) but not when I
connect the harness and use the door switch. The harness lights my test lamp
(very weak) on both terminals of the connection (switch side) when idle, no
change when switch applied. Seems like it should be pos/neg and reverse to
go either up or down. There is a 'computer' inside the door with the letters
MMC. Wonder if there is a master reset.

The motor will not move at all so I cannot apply the 'auto up' procedure to
adjust and I tried the "open the door, press down on window switch, turn key
to on let go" but that had no effect.

I disconnected the battery hoping for a reset, no joy. Fuse 18 (passenger front
window 20A) is not blown. Fuse 17 (Power window MPCS 7.5A) not blown.

Any ideas?
