2005 Buick Rendezvous windows go down but won't go up. Only the drivers side buttons close the windows

Power window motor is bad

The adjustment is on the drivers side under the vehicle. Lube it or put heat to it, They rust badly. Most likely not your problem though. You'll have to replace cables.

Try checking the fuse box usually located under the dash on the drivers side for a blown fuse. My be listed under power or power windows.

Go to the dealer and order the needed parts first.

Sounds like you have bad front wheel hub assemblies... google it, GM won't admit there is a HUGE problem with them, but there is. Just got back from a trip, had to replace the driver side front tire, wore to the steel belt. Went in for an alignment after new struts and whala, once again I have a bad assembly on the drivers side. This is the THIRD time I have replaced it in less than 2 years. Don't pay the dealer to do it. Get the part at the auto parts store and do it yourself. You'll save big bucks and it will wear out before the lifetime warranty so your next one will be free (if you install it yourself).

check for power to solenoid , repair wiring or replace solenoid (actuator)

I have this problem in my Buick Park Avenue. The two passenger side windows and the driver window work fine, but the rear driver side window won't close if it's opened. I disconnected the wire from inside the door to avoid further problems.

First try helping the window up, by gently pulling on it while you push the button. If this doesn't work and your vehicle is still under warranty, take it back to the place of purchase, the window motor will need to be serviced or replaced.


Buick Rendezvous Window Motor

most likely the window motor gear has failed.

Found a print of the light assy. Pulled it straight forward and it came out.

I had the same problem with mine. It ended up being a bad driver's window button. You have to replace the entire drivers side window control panel. One way to check if yours is bad is with a multimeter, or ohmmeter. Just take a small screwdriver to the side of the control panel (Entire panel...not just the button) and pry it up. It will pop out with a minimum amount of force. Next, disconnect the wiring harnesses from it and remove the panel. Make sure the car is off with the keys out before you do that. Check the continuity between the 3 pins on the underside of the button in question. You should have less than 1 ohm between the center and bottom pin when the button is in the down position and the same on the middle pin and upper pin when the window is in the up position. If you have anything more than 1 ohm, the panel is bad and the entire thing needs to be replaced. It costs like $400, luckily mine was covered by an extended warranty. If you do not have access to a multimeter, you can test it another way. You need to take the entire door panel off! It's really not as bad as it sounds. If you need help with it, get back to me for directions
