power sliding door malfunction
The passenger side power sliding door keeps opening and closing and will not stop, there is no manual operation for this door. It worked briefly after buying, (bought used about 2 years ago). With the on/off switch disabled, the door finally closed but not completely, the dashboard light states door open. Absolutely no one knows how to fix this problem....incl
Skip, just did a quick look around and it seems that this is a common problem. First check on the fuses in the instrument panel fuse box. 1st= 15amp, #21, power SLD Door and 2nd RT SLD DOOR,#25, 40 amp. You can pull them out and look to see if they are okay, use a multimeter too check those.
The door is controlled by the" power sliding door module (PSDM) monitors the door position at all times including during manual operation. The PSDM supplies the power and ground to operate the power sliding door (PSD) motor and clutch. The direction of the motor rotation is determined by which of the motor control circuits is supplied 12 volts and which is grounded. The PSDM varies the current flow through the motor ground circuit to control the speed of the motor as necessary. The clutch enables the PSD to be operated manually when de-energized, or by the motor when energized. The PSDM uses the PSD detent switch to determine when the door is latched, ajar, or open. The detent switch is part of the sliding door lock assembly. The detent switch signal circuit is supplied 12 volts through a resistor within the module. The signal circuit is briefly pulled to ground as the door moves from latched to ajar while opening, or from ajar to latched while closing. The detent switch signal and ground circuits, along with all other PSD circuits, are connected to the body harness through the sliding door contact plungers and B-Pillar contact pads when the plungers and pads are in contact with one another. The unlatch actuator is responsible for latching and unlatching the PSD." So, this may be something you need to start looking at. I will try and get the repair manual and will let you know. Hope this is a start to get you going.
