I wouldnt trust anyone with that except the dealership service department.

each door has there own door lock solenoid, the only thing they have in common is one fuse, either they all work or none of them will work. So I would say the door lock actuator inside the door has failed.

You need to remove the carpet on the passengers side and check the wireing harness,take off the tape and visually inspect it.You are likely to find broken splices ,bare wires or wires shorted to each other or to ground.

if you have any knowledge of automotivce electrical, (and that you need to use a "circuit tester" and not a test light) test for power when someone presses the button. it wouldnt be uncommon for most vehicles for the lock actuator/solenoid/duty actuator to wear out, get weak and fail. this is most probable. given that this is an 08, have you checked withe dealer to see if its still under warranty. if we are only talking a few miles and they wont do anything, look in your owners handbook and get the 1 800 number and get GM's customer service involved. cheers.

TRY USING THE BOTH WINDOW SWITCH TO EACH WINDOW.IF THEY WORK THE MASTER SWITCH IS FAULTY

not the fuel fillter try the soloniod

It sounds to me like you should prepair to buy a new battery. A question I have for you is,"Do you have a lot of electronics,ie;mega watt sterio,vidio equipment,ect.? If you have a lot of electronics you will need a higher amp altinator to keep thing under control. If the battery is 3 or more year old, I would have it checked. The alternator is doing it's job.

It is a real pain. You have to remove the whole front bumper cover. I work for a GM dealer and we hate to change those bulbs. Sorry. Is it not still under warranty? Good Luck.

Hi the park assist has a fault code that's why the switch does nothing

I think this lives under the washer tank drivers side front

get the lockpick. gen5. about $249. just google for your vehicle

I've never heard that there was a difference in the frames but who knows...

Depending on what you have for diagnostic knowledge and tools. You may want to send it in for diagnostics and repair. I can tell you that your vehicle's BCM (Body Control Module) controls these circuits. If it was a t my shop. I would first look for any fault codes. Then through the scan tool, manually command the doors to lock and unlock. Depending on what I find, take a closer look at the master control switch. This is in the drivers door and opens/closes windows and locks/unlocks doors. I'm forwarding you a couple wiring schematics just in case. I don't want to slow you down. FYI under the hood, inside the power distribution box. There is a relay for the tailgate lock/unlock. Any questions please feel free to write back. Good Luck.

Remote Control Door Lock Receiver (RCDLR) The remote control door lock receiver (RCDLR) is a multifunction module that operates both the keyless entry system as well as the tire pressure monitoring (TPM) system. When an RF message is received from a keyless entry transmitter, the RCDLR interprets this signal and will request via serial data that the body control module (BCM) perform the specific function, i.e. door lock, door unlock, or vehicle locate. The RCDLR also sends messages out to the 2 Way Advanced Remote Start transmitter. Remote Control Door Lock Receiver (RCDLR) (AP3 or AP8, without E52) Top rear of the passenger compartment above the rear window Remote Control Door Lock Receiver (RCDLR) (AP3 or AP8, with E52) Left rear of the vehicle behind the D-pillar trim panel Body Control Module (BCM) On the lower left side of the I/P to the left of the steering column Good luck !

On my 04 Grand caravan,the E G R tube went through a pipe about the size of a quarter to the valve cover.it should have a rubber grommet in it

bad cell inside battery,so it won;t hold the charge,if battery checked OK,it might be a bad bridge (three diode inside alternator,change AC to DC) in your alternator

temp control is the board
