If you are suddenly faced with a necessary sliding auto door repair, here are some things you should try before consulting a professional.
1. Check the Fuse
Many times a costly garage visit can be avoided by simply checking the fuse box. Dig out your owner's manual or look up the fuse diagram online to locate the fuse that correlates to the door. This may be located below the steering column or inside the engine compartment. If you find that the fuse is blown, replace the fuse and test the door.
2. Check the Auto Door Switch
Most vans with automatic doors have switches located on the dash that can turn the automatic feature of the doors on and off. Check to see if one of the switches has been turned off by accident.
3. Disconnect Battery Cable
As weird as it may seem, sometimes all you need to do to fix a sliding auto door is to simply disconnect the positive battery cable. Once disconnected, wait for about four minutes to give the system time to reset and then connect the battery terminal again. This will reset any electrical glitches in the system.
4. Seek Help
If a reset didn't work and the fuse isn't blown, then chances are the door motor is malfunctioning or broken. Take it to a garage and ask for a diagnostic of the door motor and an estimated repair cost.
