ES300 Malfunctioning Drivers Window

[coppens1]

Dear Fellow Lexus Owners, I have an 01 Lexus ES300.  The drivers side window is malfunctioning in the automatic mode after I had the window regulator replaced.  

When I click the window control for automatic closing, The window automatically closes and then comes back open, about 6 inches.  I have to close the window a little at a time to fully close it.

Does anyone else have this problem?  What is the solution?

 Let’s explore some potential solutions:

1. Window Motor Retiming:

   • Sometimes, the window motor needs to be retimed after a regulator replacement.
   • To do this, the door panel and regulator may need to be removed, and the motor retimed.
   • Consider taking your car to a dealer or a professional mechanic for this adjustment.

2. Window Motor Reset:

   • Try resetting the window motor by following these steps:
     1. Remove the window motor from the regulator.
     2. Mark the teeth on the window motor.
     3. Plug the motor in and spin it 5-8 times.
     4. Reinstall everything and test the window function.

3. Check for Obstructions:

   • Ensure there are no obstructions (such as debris or misaligned tracks) preventing the window from closing fully.
   • Inspect the window tracks and seals for any issues.

4. Inspect the Regulator Installation:

   • Double-check that the window regulator was installed correctly.
   • Verify that all bolts and connections are secure.

Dear Dave, When I sent your email to my auto repair shop, they told me that the window was malfunctioning because the window regulator I supplied for the repair is a Toyota Camry regulator, not a Lexus ES300 regulator.  When I bought the window regulator, the vendor told me that the regulator was the same part for Toyota Camry or the  Lexus ES300 regulator.  It is a different part no, but the same part.  

is the repair company correct, or is the regulator the same?  Why would the regulator not work in the ES300?
