I need a left front door module, the dealership can't find one and my car is sitting there waiting for me to bring it to them.

You may need to bring it to the chevrolet dealership the control module may have to be calibrated. I would call the dealership and ask them if the control module needs calibration...

Sitting in your vehical, front driver's side. Look down to where your "LEFT FOOT" is. Undernealth the dashboard, just in front of the door. Their is a plastice pop-off panel cover. ON THE INSIDE PANEL IS ANOTHER WIPER DELAY MODULE. Take your "Hidden Wiper Relay" Module out an bring it to your local junk yard so you make sure it's a match...That should do it.. The module is just about the size and shape as a pack of cigarettes.. No Special Tools needed... Just a flat head screwdriver..
I had to show it to someone who worked at the junk yard because it was gone from every vehical I looked at... Plug it in your truck before you pay if you can. $15.00 dollars...
Good Luck.

check door locks fuses and relays.if all is good and you cant operate door lock buttons manually problem could be in the generic electronic module.if door locks dont work from the remote battery could be dead in remote transmitter.try to reset door locks control module first obtain all remote transmitter.sit inside vechicle with all doors closed.switch ignition from off to on 8 times in 10 seconds. doors should lock then unlock.when this procedure works then press any button on any of the remote transmitter doors should lock and unlock.if all fails let dealership fix..

You should start on the most far wheel - typically it's rear right wheel, then rear left, then front right and front left.

Hi, the problem you are having is not with the remotes the problem you are having is with the central locking motor, this would not have failed due to the remotes not working as the other doors lock then this would rule out the remote being at fault as its only one sensor that picks up the signal then this locks all the doors.
the problem is with the central locking motor inside the door, it may just be that a wire has come loose or if you can hear it working but it dont lock then this means the motor unit will need replacing.

either way the whole door panel has got to come off so you can get to the motor and the wires.

let me know if you need further assistance ok

plz rate this solution as i have a whole page of unrated posts, thanks

you need to replace the left front door speaker

Its most likly the relays or switches

Visit Autozone.com and look at their online repair manuals. Most computers are in either the driver or passenger kick panels under the dash just in front of the door, in the engine bay, under one of the front seats, or behind/under the radio in the dash.

you have put your vehicle in learn mode. there is a special tool to relearn tire positons. take vehicle to a dealership and have tire pressures corrected and tire pressure sensors relearned. your tire pressure info. is on your drives door, 07 tahoe should be at 30psi .you can try pushing check and wait for honk, then let air out of left front tire until you hear a honk, then right front, then right rear, then left rear. by then your sensors will be learned but you will have four flat tires, it'll be easier to have someone reprogram using tool.
