I have an '02 Buick Rendezvous that doesn't have a overhead DVD player installed in it. Was wondering if I could get a factory one from an Uplander, Terraza, or Montana and install it in my Rendezvous

The trouble code should tell you which 02 sensor? The 02 sensors are in the exhaust, sensor 1/sensor2, whatever, bank 1/bank2, whatever, before the cat, after the cat. You have several 02 sensors in the exhaust, don't know which one?
You should be able to remove/install with proper size wrench or deep socket. They do make an 02 sensor socket that has that slot in it, not sure if you need that, though.

yes,u can get it done for sure.u might need wiring kit to joint the system together.make sure u can get the kit before to buy aftermarket system.

try unhooking battery for a few minutes and see if resets system unlikely it will work but worth a shot. will most likely have to get it out with tweezers or a pick. when you do see if it is warped this would cause it to hang up

how do I remove my dvd player in my 2006 chevy uplander? I need to replace it and dont want to spend that kind of money to have it pulled out. I dont see any screws or bolts

www.homelink.com will explain

SCAN IT TO CHECK FOR SECURITY ANTI THEFT SYSTEM FAULT.

Have you checked the Aux switch near the bottom of the center control console.
There should be a knob with: Aux, Off, 1, 2, 3. This is the switch for the rear AC blower.
If the driver wants to control the rear AC, use the 1, 2, 3 settings.
If you put it on Aux, Than the rear AC is controlled by the passenger in the back seat using the extra controls located on the Overhead DVD player. (The front AC must be on the rear to work)

any I/R headphones will work - you will not need a new transmitter.
They do not have to be "Buick"... any brand/model will work.
