2003 Chevy 2500HD 6.0 auto. Truck won't start. Before, while driving the door locks were locking and unlocking like when you shift into drive or into park. Shut off truck. 1 hr later it won't start. Jump starting didn't help (I didn't think it would). Everything works, lights, radio, etc... It does not turn over. Maybe its a trans module? Thanks for your help.

No , it's not a trans module . Do you know how the starting system works ? Do you know what a wiring diagram is ? Do you have an know how to use a volt meter ? Going here http://www.bbbind.com/free_tsb.html free wiring diagrams . You need to look an see what all is involved in the starting electrical circuit before guessing as to what the problem is .
Enter your vehicle info - year , make , model and engine size. Then under system click on engine , then under subsystem click starting .Click the search button then the blue link. Looking at the wiring diagram i see IGN E fuse 10amp , the park neutral postion switch , starter relay , IGN A fuse 40 amp . I do not see a trans module , but i do see the PCM -powertrain control module . The PCM has both trans an engine control modules in one box.
The PCM will energize the starter relay if there is no anti-theft system . Do you have a security light lit on the insturment cluster ?
No crank good starter how to troubleshoot any car Hyundai

the noise is the relay clicking for the shift lock release....the auto door lock setting needs to be turned on...it should tell you how in the owners manual...

SOURCE: Radio, Key auto door lock/opener, interior lights not working.

Most likely is a fuse. There is a fuse box at the end of the right side of the dash. Open front passenger door and there is a cover that says fuses on the end of dash. There is also a fuse box located under the hood at the right front of engine compartment. It should have a cover with a round knob in the middle of it .Unscrew the knob to remove cover.

SOURCE: 2001 Chevy 2500HD 6.0L, Hard starting.

Check the fuel pressure, bad fuel pump or sock on the fuel pump and fuel filter check spark plugs and check distributor cap, a fuel pump is $273.00 or a bad injector $110.99 or BWD Fuel Vapor Pressure Sensor for $35.99 any of these parts could cause the problem, so without doing a fuel pressure test it is a guess, if the vapor switch is bad it could cause a long crank time if the fuel pump is bad it has a check valve in the fuel pump, if the check valve goes bad the pump can't maintain fuel pressure so on start up the fuel has to pump from the tank all the way up to the fuel rail, if the injectors is bad it could leak after engine shut down and cause you to lose fuel rail pressure. Also the fuel vapor sensor could be stuck open and could cause the problem, all need to be tested, you can rent the fuel pressure tester from AutoZone or advance auto or Shucks they return your money when you bring the tool back as long as you buy the parts to repair it from them. That would be the first thing I would check fuel pump pressure and if you replace the pump then change the fuel sock as well. That model was not meant to burn ethanol and can kill the fuel sock the fuel pump and filter.

2002 chevy Blazer 2 door. Power locks,and liftgate stop working.The locks will engage when I shift to drive and will disengage when placed in park. Where do I start?

Hi,
Plz explain...are the locks supposed to lock/unlock when you put the car in Drive/Park, or not?

Does the lock/unlock SWITCH on the DRIVER'S door work/not work? If applicable, does the PASSENGER's door lock switch work?

Probably is the actuator. Common problem. The actuator is part of the complete door latch. Hopefully that is what you got from 'Dorman'.

When my 02 silverado 2500hd is in 4x4 the tires are locked and the truck won't move until I shift back to 2hi. Differential or Encoder Motor?

You can take this with a grain of salt but I am a junior in high school taking auto mechanics and my teacher use to work for a chevrolet dealership where they had a geo tracker come in because it would drive fine until placed in 4 wheel drive. Once placed in 4 wheel it would not move because front and rear differentials were geared differently from factory causing the wheels to lock up. If it has never been able to go into 4 wheel since you have owned it I hope this will help...

Why are the door locks lof my 2004 mazda 6 ocking and unlocking on their own?

If they lock after you start to drive forward...and automatically unlock when you stop and place gear shift in park...that is a safety design...Many car builders use this, with certain variables as to when to auto lock, and auto unlock...if the locks are working on there own after you have started driving...that is another problem. Your owners manual should address how the locks in your Mazda 6 are designed to work. Hope this helps.

Power windows and door locks don't work on 2006 silverado

it's not the girlfriend, it is the PDM, passanger door module, got mine a rock auto for 120.00, need to get the one specific for your VIN, not on most parts lists, it is a control board for all power windows and locks and the keyless entry. My cadillac was doing exsactly what your truck is doing. once you put the new one in you need to reprogram the remotes, not too hard, hold down lock button on drivers door, ignition on/off twice, let go of the door lock button, press both unlock, lock buttons and hold untill you hear the lock unlock. your program sequence might be slightlyl different check the web.
good luck.
