Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Hello, thanks for posting
The window may have to be re initialized, try this , if it doesn't work there may be a problem with the regulator binding up or the back door ecu has a malfunction.
Roll the window up as far as it will go
roll it down and hold the switch down for about ten seconds
if the window goes back up all the way hold it there for another ten seconds, that will re initialize the computer.
Check to see if the regulator may be getting stuck, remove the bolts that hold the glass on and slide it all the way up then see if the regulator moves up as well, the window limit switches make contact with the glass when it's all the way up, if the regulator still stops halfway up the problem is most likely the backdoor ecu.
