Having issues with auto door locks, windows and side mirrors
• The remote buttons on the key will only unlock the driver's door, however, no matter how many times you push the unlock button the car alarm still goes off when you open the door and you then have to press the unlock button again to silence the alarm, this is true even if using the key to unlock.
• However, once you get in the car you can use the passenger button to unlock the other doors and the back gate but if you manually unlock one of the other doors and open it with the driver's door shut the alarm will go off but if you have left the driver's door open the alarm does NOT go off.
• The windows will not roll up or down from any window button position, not from the drivers panel or individual doors.
• The button to adjust the side mirrors does not work.
• We have replaced all labeled fuses for the doors, power windows, power locks and remote mirrors. No fuses that were changed appeared to be burned out.
• Also, there is no check engine light indicating an issue.
All these issued happened at the same time, one day everything worked and the next day they did not.

Opening the door with the key should turn the alarm off. It is the certified way to get into a car if the key fob remote fails. Get a local auto locksmith to get you a new fob and key and program it. Keep the old one as a spare key.
I can help with a little testing. On the hinge side of rear passenger door, should be a wiring harness. Probably has a protective rubber boot covering, pull the covering back far enough to get at wire colors in the diagram. One wire is voltage the other is ground depending if the window is going up or down. Use a test lite to check. Key on, I would think.Your front passenger window works ok? If the wires check out good for voltage and ground, could be something wrong with window motor?
it is not the actuators, try a different remote, you may have an issue with the car security system/body computer not functioning on the unlock driver door command, one press of remote is unlock driver door and 2 presses is unlock the other doors.
reset the central locking system by locking car with key in drivers door and hold key over for 30 secs.then pressing and holding down unlock button on keypad OR unlock door with key and hold key over 30secs (windows may go down, thats okay,some cars are fitted with auto windows)then press and hold lock button on keypad.making sure that in both cases you know the keyfob battery is in good nick....should reset system
1. sitting in driver seat, with driver's door OPEN, press lock/unlock
button ON THE DRIVERS DOOR to lock all doors, then manually unlock
driver door only. 2. Insert YOUR key in ignition, DO NOT TURN, then remove key. 3. Using the same lock/unlock button ON THE DRIVERS DOOR, slowly press lock-unlock in 5 cycles 4. Shut door. 5. Open door. 6. Using the same lock/unlock button ON THE DRIVERS DOOR, again slowly press lock-unlock in 5 cycles 7.
With the door open insert your key into the ignition, turn to 'on'
position (DON'T START), wait 5 seconds. Turn off and remove key. 8.
Locks should cycle once (Car will lock and then unlock once by
herself). If they don't cycle or they cycle more than once, do steps
1-7 over. 9. Now using the remote, push lock button, hold for one
second, then release the button. The locks should cycle once. If not,
start over and go slower. 10. Close the door. 11. Open the door. 12. Press the lock button on the remote. The locks should do a lock-unlock cycle. 13. Close the door 14. Press the lock button on the remote, the doors should lock. 15. Press unlock button and the doors should unlock.
Your chevy uses two fuses for the system. The power lock actuators are on the 15 amp fuse inside the truck. The fuse for the switches (locks and mirrors) are under the hood. For 99 to 04 (I think those are the years) there is a TSB on replacing the 3 amp fuse under the hood with a 5 amp fuse because this is a well known problem of having these blow.
Your drivers side window is a different issue. If the rest are working your problem is in the motor or getting power to the motor. The wires that go from the body to the door often crack and break with the opening and closing of the door.
make sure than you have not split any fluids on the passenger front door most of the times is where the module to control the windows and doors is located, try by unpluging the batterie and the after a minute plug it back and see what happend but if any of your ft doors have been split with liquid or rain has gone inside then most likelly the module got moisture and not working
