My battery was replaced today, when I got to work I tried to lower my window and it didn't work. Tried the others, same thing. So happy to have found this website. Haven't gone back to my car yet, but have no doubt this will solve the problem. Thank you!

 

It's amazing what you will find in your owners manual.



And for those that don't have one, you can view it here:

When attempting to "normalize" my windows after I replace my dead battery.... I was able to get each window back working except for one window........ the rear passenger side window.

In the above directions^^^^^ they indicate to lower the window "half way" then hold the button down....I mistakenly lowered the rear passenger window ALL THE WAY DOWN. Now it seems to be stuck. I can't get that window to normalize now and have tried numerous times to no avail. It's the only one that won't work.

Any help is appreciated

 

Disconnect your battery again and reset them all correctly.

 

I don't lower them half way, I lower them the entire way. This is how I do it:

Lower the window, keep the switched pushed down for 3-4 seconds after the window lowers all the way...then raise the windows and keep the switch pulled up for 2 seconds. That's it....

 

As repeated "normalization" of the one rear passenger window wasn't working.
I took the vehicle to Lexus...found out I need a switch assembly.
They were able to get the window up for me though as I declined the fix from them.

The part (8403060032) costs $239 from Lexus.
To save some cash decided to go another route to get the part for much cheaper.

 

The window switch assemble is actually serviceable if you remove it you can carefully open it and clean the contacts. Its most likely dirt or moisture got in there and corroded the contacts. You could also spray some contact cleaner [ radio shack ] on the top of the switch and it might be able to wick down and clean it without taking it apart.

 

Thank You mrblister

I will run this method by my trusted mechanic and see if this can solve my problem.

 

Just changed my original battery after 9 years, but my 2005 GX has only 45k.

 

wow 5k a year.

 

Have you changed the timing belt yet? There's a time limit as well as the mileage limit on them.

I think the timing belt is 10 years, will double check the manual.
So far I changed the battery and tire pressure sensor(out of battery).

 

I was either living close to work(walk sometime) or working from home for the past 8 years.
I leased a Nissan Leaf last year, so it will be less then 1k miles for these 2 years on my GX.

 

Just did this, very good to know!

 

Thanks , it worked
