What is a Power Sliding Door Switch?
Power sliding doors that open and close automatically are included on most vans today. These side doors are triggered by a signal from a button on the key fob or from a switch inside the vehicle.
How do Power Sliding Door Switches work?
When the Body Control Module (a small computer that monitors and controls dozens of vehicle body functions) senses a signal from the sliding door switch (or from the key fob), it gets to work organizing the operations of the door. A group of relays and actuators unlock and unlatch the door. Then the sliding door motor uses a mechanized system of cables, chains, and rollers to move the door along tracks in the side of the van. When the door has opened or closed all the way, the motor is turned off and the door is either locked open or latched shut. It can be a fairly complex operation, all at the press of a button.
What are the symptoms of a bad Power Sliding Door Switch?
When the power sliding door switch is failing or goes bad, it will either cause the door to open and close intermittently, or it will not work at all. In some cases, a defective switch might cause the door to open or close suddenly and unexpectedly. If the sliding door does not open or close when the switch is pressed, or if it opens on its own, there are several possible explanations. A bad switch is one possible cause.
Can I drive with a bad Power Sliding Door Switch?
In most cases, a power sliding door can be opened and closed manually if the switch is bad. In this case, the van can be driven. If, for some reason, a door will not close all the way, the vehicle should not be driven until the problem is inspected and repaired. Similarly, if the switch is defective and causes the door to open or close unexpectedly, not as a result of any driver action (such as bumping the switch accidentally), the vehicle should not be driven.
