Our '98 Sienna now has trouble getting both windows to return up to the closed position. I see online that I can get either a replacement window motor OR the motor/regulator assembly. But how do i know if i need to get the regulator as well?
Symptoms: Both windows will go down with little trouble, but when going up they move up a few inches and stop. At that point, they cannot go up or down at all. But after a few minutes, they can go up a little further and stop again (doing this a few times inches them closed over time). If i hold the glass by hand and lift, that usually helps the motor to close all the way. I have tried the suggestion of applying silicon lube to the window seals (assuming it’s a friction issue) but that had no affect.
Any thoughts? I’d like to do both windows before winter sets in.
