The rear passenger Looks like the window reg. is going has anyone done this job themselves? If so do you have any pointers?
 
You may try some soapy water sprayed into the window

guide channels...it will act as a lubricant and may help with your situation. I once worked in an automotive manufacturing facility, and that was our solution for slow window movement for brand new vehicles. Use about 1:20 soap to water ratio.
 
Isn't it strange to have this problem on a 99'? I'll try the soap and water.
 
I have the same problem in cold weather with my 98, both rear windows are slow, especially the passenger side. In sub-zero weather I've had to grab it and pull up to help the motor close it.
 
I have the exact same problem on the passsenger side rear window. Where exactly would you recommend spraying the soapy water mixture? Inside, outside, both? Just along the edges of the window or along the entire length. Thanks.

No, it sucks, but it's common I think. My '99 does it on the rear PS. I took the interior panel off once and sprayed some Toyota lubricant (It may have been silicone) and that helped for a while. I think it's got more to do with electrical current than lubricant. It seems that that motor may be the longest run for the power to the motor and it doesn't get enough juice.
 
It seems strange to me that Toyota missed this... on such a nice truck. I will try putting a little lube on the tracks.

I would spray the soap inside the two vertical window guide channels...strange, but my rear windows are slow to roll up...even on warm days. Maybe there is a design issue/variance with the rear window glass/regulator.
 
I would also run a battery/charging system test. Sometimes a weakness there shows up in the chassis electrical components first. (experiance from ford crown vics with multiple battery/charging system failures) I think that is because they don't engineer them to the same level of overkill as the drivetrain components.
 
I have used silicone lubricant spray with great success on slow windows. The lubricating effect lasts for years as well. Just spray the guide channels down as best you can and roll the window up and down several times. When I picked up my 98 LC, the windows all went up/down at different speeds. Sprayed them down and all is good.

I am with Rich on this, but...

The only problem with many silicone-based lubricants is that they really seem to attract dust...I still swear by silicone for this problem, but I would use the dry-type silicone by 3-M..it not only reduces dust build-up, but it also doesn`t leave a gooey film everywhere...it truly is a wonder-lube !! :)
