The windows on the passenger side will not go up or down and the lock wont work or the seat. Also the airconditioner has no electricity either - is their a wiring harness that is disconnected or what? new capreting was put in before i got it and did they bump somethng ?

The windows need to be re-learned.
- Park the car on level floor. Shift the gear lever to P or N. Pull up the hand brake. Start the engine.
- Sit on driver's seat. Lower the driver side window. Keep the button pressed for three to four Seconds after the window glass sits completely.
- Move up the window glass and do the same as above.
- Do the same with passenger side window glass while sitting on the passenger seat.
- Repeat the same procedure for rear windows one by one from their own buttons.
- Sit on a drivers seat and operate all the windows one by one.
If the problem persists, pull up the body diagnostic error codes with Diagnostic computer or re-learn the windows with the same machine.
How to diagnose this problem ? Viewing wiring diagrams to see what all is invovled in these electrical circuit's , check power supply's an ground connection's using a DMM - digital multimeter !
What type power seat's ? does it have memory ,heated an cooled etc ?
Power Seats System Description and Operation
There are 2 options of power seat systems available in full size trucks. The first is 6 way driver and passenger power seats without memory. The second is an 8-way driver seat plus 4-way lumbar with memory, heat and optional cool function. While the passenger has 8-way power seats with heat and optional cool function. For the driver memory seat operation, refer to Memory Seats Description and Operation. Power seats without memory are completely controlled through the power seat switch. Battery voltage is supplied to the power seat switch through the power seat circuit breaker. While the seat adjuster switches are in an inactive state the switch contacts are closed to the power seat switch ground circuit. When a power seat switch is pressed to an active state the switch contact is closed to the battery voltage supply circuit. Each seat adjuster motor is controlled by the power seat switch through 2 motor control circuits. The seat adjuster motors are bidirectional and the direction of adjuster motor rotation is determined by which of the adjuster motor control circuits is switched to battery voltage while the other remains grounded.
If it has memory seat's there is a control module !
Battery voltage is supplied to the driver seat module through a 25 A circuit breaker. The driver seat module supplies the seat adjuster switch assembly with a battery positive reference voltage. While the seat adjuster switches are in an inactive state the switch contacts are closed to the adjuster switch common circuit.
Both right side windows have a seperate power supply from the left side window's ,has RT DOORS circuit breaker CB1 - 25amp. location left instrument panel fuse block . Circuit breaker's very rarely fail .Do the door lock's work on that side of the vehicle ? The windows won't work with their own switche's ?
The DDS controls the passenger window through a GMLAN message to the PDS. When a power window switch is activated in the up or down positions the PDS supplies power and ground to the window motor control circuits to drive the window motor in the required direction. Prior to activating a power window motor the PDS will supply the control circuit with a low current bias voltage in order to determine that a short to ground condition does not exist, and during window motor operation the PDS continues to monitor the motor current to verify proper window motor operation. (Scan tool support is available for this system)
Check PDM fuse 4 15 amp ,this supply's B+ voltage to the DOORLOCK/WINDOW switch passenger side . Check for broken wires inside the flex boot from the body to the passenger door .
Its time to stop being afraid of the unknown. there is no doubt that you will need to remove the inner door panel to access the electrical modules behind the buttons. https://www.youtube.com/watch?v=p2_f7NkjH8E hope this helps.
