2000 Silhouette power sliding door motor starts running while I am driving the vehicle. It will not stop even when I park the van and turn off the ignition. I must open the door and then turn off th

The power sliding door (PSD) includes several interconnected electronic and mechanical components. Obtain a specific customer concern in order to efficiently diagnose and repair the PSD system. Begin diagnosis with a service writer. Ask the customer for as much detail as possible regarding the conditions under which a failure of the door was noticed. Always include the basic concern, such as "door reverses when closing". The following details might affect the performance of the PSD:
?€¢
Weather conditions, such as snow or heavy ice

?€¢
The van was parked on an incline.

?€¢
The van has been parked for a long time, which may cause a weak battery.

Refer to Power Sliding Door Customer Concerns for diagnosis. Verify that all of the mechanical components of the PSD are aligned and operating correctly before you begin diagnosis of the electrical system. The electrical components cannot operate correctly if the mechanical components are not operating correctly.
I just checked out a 1999 Oldsmobile Silhoutte yesterday , same set up there is a cable inside hooked to a motor that opens the door. The one yesterday had the cable hanging out the back of the sliding door , does yours ?
Does it open manually ? There are electronics involved , sensors ,switches , a module an a electric motor .

The amount of force necessary in order to reverse the PSD depends on the position of the sliding door at the time of obstruction. The PSD action may not reverse if the following actions occur:

1. The PSD starts to close.
2. A gradually increasing force is applied on the sliding door in an effort to reverse the operation.

The PSD control module may interpret the gradually increasing resistance as a corrosive or dirty track. The PSD control module compensates for the gradual resistance on the sliding door by applying more power to the cable motor when closing the sliding door. In order to reverse the PSD at this stage of the sliding door travel, an abrupt and firm force is required.
The PSD control module operates in this manner in order to compensate for the wear over the life of the PSD. Over time the vehicle may experience the following conditions:
?€¢
A dirty track

?€¢
A corrosive track

?€¢
Ice build-up on the track (during cold weather)

The PSD control module is more sensitive to obstructions near the end of the sliding door close operation. The amount of force necessary in order to reverse the sliding door travel is less than when the sliding door started to close.
When the sliding door is within 2.5 cm (1.0 in) of the closed position, the door lock latch switch sends a signal to the PSD control module. The PSD control module determines that the sliding door is in the unlatched (ajar) position. This action causes the control module to apply full power to the cable motor in order to bring the sliding door to the fully closed (latched) position. The sliding door will close unless the force is greater than the cable motor at full power. The PSD control module de-energizes the cable motor and the clutch when the PSD control module receives a second signal from the door lock latch switch. The second signal indicates that the sliding door is fully closed and latched.
Power Sliding Door (PSD)
The power sliding door (PSD) provides built-in diagnostics. This assists the service technicians during troubleshooting.
The PSD has the following diagnostic capabilities:
?€¢
Diagnostic Trouble Codes (DTCs)

?€¢
Input/output tests

Your problem is the door thinks that it is already locked and closed. You need have the sliding door unlocked, have someone pull the handle as if they were going to open the door and then use a tool to "Open" the latch that normally would hold the door closed.

Please have a dealership that handles GM vehicles check to see if your vehicle was involved in what the trade considers a run away transmission condition involving the automatic transmissions parking pall linkage defecting thus allowing the transmission to go into drive while the vehicle is idling in park.

are all the doors shut, if so could be a bad sensor on one of the doors.

lube everything that moves on that door with white lithium grease, also lube the door latch.

HI, there is a park switch or circuit that is built into every wiper motor. Apparently, your switch has failed. you must replace the entire motor(wiper) in this case.

This is a shot in the dark, but turn the key to the on position, pull the shifter down to Drive and then take back to Park. This is to make sure that the fault is not in the neutral safety switch or that the vehicle is not fully in park. Try to wait a few seconds with the switch in the on position before trying to start the vehicle, giving the system time to be fully primed, since you mentioned that you had replaced a fuel filter. Don't know if this will help, but it's worth a shot. Hope it helps and good luck.

quite often ford steering pumps make noise, but if it is hard to steer, the fluid is probably low. First check underneath to see if there is a puddle, if there is then find and fix the leak. next, start it and get it to normal op. temp., while idling, pull the pump plug/ dipstick, check the level, add fluid if necessary. Steer the wheels back and forth a time or two, then check the level again. Double check underneath, visually inspect for puddles/wet spots. does the problem change after these steps? Theres not likely any water in it, therefore freezing isn't likely. Hope this helps.

You need to have someone or yoursef check the body control module with a compatible scan tool. Thats where the problem you are having resides. It may need a software update or replacement. You can also disconnect the battery for a few minutes, that will cause the BCM to reset and may fix it.
