1998 Chevrolet venture van door problem. 3.4L tech = JK question = When I try to open the power sliding door by pressing any of the buttons, the door motor just makes a short click no matter how many times I press the button. The door won't open or close automatically. I tried resetting the power door a couple of times and I checked the fuses. The door still does not open or close automatically. It just makes that short click sound when I press the button. I lubricated all the tracks where the door drives on and the cable that runs through the motor.
I still have the same problems no matter which buttons I push (overhead console button, beside the door button, and remote keyless entry transmitter button). Also, previously when the power sliding door used to work and the door was opened while the car was in gear, there would be a loud buzz to indicate that the door was not closed. Now when the door is opened and I put the car into any gear, there is no buzzing noise and the door does not operate. What is wrong?
Answer: 2 common possibilities. The plungers and plunger pads on the door and the door jam are corroded. Clean those off with a fine sandpaper, then put a dab of silicone grease on them. Then do the re-set procedure exactly as the steps indicate. If that does not help, then a possible door position sensor or the door control module is bad. A diagnostic using the on/off switch and the open/close switch on the system may indicate a code for door position problem. The door position sensor is part of the door motor/actuator assembly. The control module can be replaced separately.
