Power door will begin close/open only if the door handle is pulled and kept for at least a second. Problem appears to be mechanical and not electrical. I maybe wrong. If the button is pressed or if the handle is only pulled and released instantly, the door makes an effort to move and then gives up leading me to believe that it is some kind of jamming in the bottom area. Any help is greatly appreciated. Thanks.

Hello,

It sounds like it is a sensing problem or the motor is pulling too much amperage. Since these problems are mostly solved by changing the motor I would start there.

Here is a diagram (Below) that will help you get started.

Please let us know what happens, we are interested to see what it is.

Cheers, Ken

The dealer and body shops say that they don't know exactly what part it is until they open the door panel. Can a 2CarPros expert tell me what the exact part is needed to be replaced?

Pictured below are the images of the motor actuator responsible for the operation of opening the passenger sliding door from the remote control and the 2 buttons inside the vehicle hands free.
As pictured, I replaced the battery when the sliding doors were not opening with the remote or buttons but were opening manually.
It worked well for at least 5 months and now the remote and buttons are not working again but I still can open the sliding door manually.
What would be the problem? Why is the battery draining out so quickly?

Hi,

Have you checked the wiring to it for power? If you run 12v direct, does it turn on?

I attached a couple pics below. The first one shows the motor you removed. Try providing 12v. Where where the red wire connects and ground at the other. See if the motor runs.

Next, if the motor runs, conform there is power out from the ECU in the right door. See pics 2 and 3.

Do this and let me know the results.

Hi,

Yes, a test light will work. Get a good ground on one side of the tester, and then probe the red wire to see if the light turns on. If it does, the only way to be 100% sure if the motor is bad is to supply power directly to it. However, if there is power in the red wire, there is a good chance the motor is bad.

Let me know what you find or if you have other questions.

Take care,
Joe

Hi,

Yes, if it is bolted to the sheet metal or frame of the vehicle. Anything that can conduct metal and is connected with the electrical system ground.

I just received my actuator for the passenger side sliding door. Had no problem removing the panel. I also removed a few of the screws on the inner metal black bracket. Was able to squeeze my hand to reach the screws for the actuator but it seems they are stripped. I can't unscrew them Its only 2 screws but am not having any luck. Any ideas?

Yes, I was able to do all this successfully but the screws holding the actuator motor for the button in the vehicle to open the door are stripped. The Phillips head just doesn't grab because it's stripped. Also? I learned that those screws were put in with loctite glue so that's why they don't turn.

Hi,

Loctite prevents them from coming loose. However, you shouldn't have a problem removing them. How much access to you have to the screws which are stripped? I might suggest getting an impact screwdriver if there is room. Basically, you put the tool on the screw head and then hit the tool with a hammer. The tool then turns the screw the same time it is being pushed into it. The pressure from the hammer hitting it both jars the screw and keeps it from stripping. I attached a picture of one. Let me know if you have enough room to use one.

Try resetting the ECU with this procedure.

A. The Main Power Switch (located on the left side of the steering column) MUST be
in the "OFF" position (red line not showing on the switch button).
B. Place the transmission selector in "Park" .
C. Make sure the right side sliding door is fully closed (manual operation).
D. Disconnect the 12V negative battery terminal and wait for more than one (1)
minute, then reconnect the negative battery terminal.
E. Turn the ignition switch to the "ON" position.
F. Push the power door MAIN switch "ON" (red line on the switch will be showing)
and wait for 10 seconds.
G. Open the sliding door by pushing either the power sliding door control button
(located on the right side of the dash by the radio or on the "B" pillar) or the
remote switch on the key ring and allow the door to open all the way).
Wait three (3) seconds after the motor stops running before proceeding.
H. Close the sliding door by pushing either the power sliding door control button
(located on the right side of the dash by the radio or on the "B" pillar) or the
remote control button and let the door close all the way.
Wait three (3) seconds after the motor stops running before proceeding.
I. Repeat steps G and H.
IMPORTANT:
Steps G and H, described above, MUST be repeated.
J. Confirm proper operation of the power sliding door system
