Introduction: Fix Toyota Sienna (or Any Car) Power Sliding Door the Fastest and Cheapest Way

I have searched the internet and YouTube to find out how to fix my Toyota Sienna XLE 2006 sliding door problem. They were time consuming, high risk, and more expensive. My method is cheap, about $4 ($6.70 after tax and shipping in Minnesota) each door and it took me less than an hour, seriously !!!

My method is pretty generic, it may apply to other car models. By the way I am a semiconductor engineer and not a mechanics.

Step 1: Symptom of Sliding Door Latch Problem

Symptom:

When you press a button to automatically open the sliding door it makes noise attempting to open the door but fails. But if you pull the handle and hold it for a few seconds the door opens.

Problem:

The sliding door latch is not working (see the picture of the latch unit). The door is supposed to unlatch first before it triggers the motor to pull it open. Most common problem is the motor of the latch fails.

My simplest solution:

Replace only the motor of the latch instead of the entire latch unit.

Step 2: Open the Inside Door Panel

What other people did:

There are many resources such as YouTube of how to open the inside cover panel so I will not go into detail here. What other people do is removing the cover panel then remove the inside metal panel to gain access to the latch unit. It's time-consuming and many things could go wrong. After removing the metal panel, it is still not easy to remove the latch because it uses non-standard fasteners. I saw on YouTube people struggled with removing the latch unit.

My method:

Only partially open the cover panel, lift its bottom up and use a box (or anything) to hold it up. No need to remove the inside metal panel.

Once you partially open the cover panel you will see the latch (see the picture).

Step 3: Replace the Motor of the Latch

I used a rotary tool (1st picture) to cut open the latch where the motor was (2nd picture, red circle where the motor is).

The 3rd picture shows what you see after you cut it open, the motor of the latch. The 4th picture shows a closer look at the motor. Remove the motor. The 5th picture shows the cutout piece of the latch.

The label on the motor shows the part number (6th picture). In my case the part number was PAN14EE12AA1 for Toyota Sienna 2006 XLE, I ordered it from DigitKey for $6.70 (after tax and shipping) for each door.

After getting a new motor, insert the motor back. You may need a magnifying glass to view the flat side of the motor shaft. Align the flat shaft of the motor and insert it. The motor has two electrical plug-ins, they should face outside.

I used a hot glue (7th picture) to glue the cutout piece (5th picture) back to the latch.

The last step is simply put the cover panel back and you are done. I finished it in less than one hour the first time, the 2nd time would be even quicker after knowing exactly what to do.

    This was an excellent idea! It certainly got me started down the "repair it instead of replace it" path. I started this project this weekend on my wife's 2005 Toyota Sienna & used the photos you provided as my reference point. Instead of cutting the motor out from the housing, I used a pair of side cutters to cut through the center of both tabs holding the housing in-place. The tabs basically shattered when the cutters pinched down on them. Once the housing was removed from the door, there are 3 small screws that hold the 2 housing pieces together and will easily allow for replacement of the electric motor. The 2005 uses the exact same Digi-Key part number so I went online and ordered 2 new motors for both side doors and am excitedly waiting for the parts to arrive. Thanks for the excellent documenting of your fix which gave me the courage to move forward with repairing my wife's van!

    Both doors are fixed now and working perfectly again. I used 2 short metal screws I found in my "junk" drawer to easily reinstall the housing against the door panel (I added some large washers on top of the screws to "press" against and hold the housing in place), reconnected the linkage bar and it was back to working order. A very nice, low cost fix! Made my wife and the grandkids happy!

    How did you find the part number for your year of van? I have a 2008 and my guess is that the same part would work but I am not sure how to verify that. I am going to be so grateful if this fix will work for us!

    If you pull out the motor then you can find out the part number.

    Search on digikey the motor, and figure it out. You can also ask dealer whether the latch unit is the same.

    It's the latch motor issue, it's separate from the cable.

    You need to be more specific on that.

    No idea, I am not a mechanics, just an engineer who happened to find a trick.

    I am not sure I understand what you meant by "magnet itself".

    Magnet itself ? I guess you meant after the door slide in it didn't close. That's a separate problem with a separate sensor and mechanical pull the door in.

    Ordered motor from Digikey, used box cutter to remove the plastic shroud, popped on new motor after lining up flat side of spindle on second try, JB Welded plastic shroud back on. Thanks to Instructables amazing hack, I saved over $1000 that the local repair shop was asking to replace the actuator on my 2005 Toyota Sienna XLE. I AM STOKED!!!

    I had just replaced the door motor and cable assembly when I realized that the door actuator motor was ALSO gone. By that point, I had put most of the door back together. I LOVED your method of getting at the motor. Worked like a charm. Thanks!
