I'm not sure what you are writing. Does the gear shift selector move but without any resistance? If so, this could be a broken shift cable. If not, the transmission could have lost power and is in need of some type of repair. I would like to provide you with more information but I need more specific details about your SUV, warning lights, maintenance history, recent repairs or engine codes. Did this failure happen out of the blue or get progressively worse over time? Let me know if you can think of anything else. Good Luck.

Have the FAN CLUTCH checked. they are a common failure. Get a AC DELCO or the part from the dealer. Why was the radiator replaced? Heater work OK? A/C works OK?

look in your owners manual it will tell where the fuse for low beam is. window could be switch, motor or ground. you will need to pull door panel to check motor and wiring.

Standard shift trans? Shut vehicle off and select reverse,if you can operate in reverse now,the trans is ok but the clutch may need adjustment or is damaged as it may be dragging and not releasing fully when your foot has the clutch pedal FULLY depressed.

Kirkasmann, P1481 is most definitely your fan clutch, it's very common on our platform. Only wires to check is the connection on the drivers side shroud. You said replaced "again"?. I've had bad ones out of the box, or it would tick tick tick. Buy a lifetime warrantly fan clutch for this reason, plus it's easy to do (as long as you cut a notch in the top of the shroud where the upper radiator hose is).

02 I6 doesn't have one. I believe 06+ have them, but not the older ones. My 06 does have one, located right after the throttle body towards the air box.

This could be a problem with the encoder module - you will need to take it to a dealer and have it checked/fixed.

The power windows on your vehicle are controlled by an electronic control module , as are the power mirrors !
Power Window System Components
The power window system consists of the following components:
• Driver door module (DDM)
• Passenger door module (PDM)
• Body control module (BCM)
• LR power window switch
• RR power window switch
• Window up and window down relays in each of the rear passenger window switches
• Window lockout switch
• Reversible power window motors in each of the doors (circuit breaker protected)
• LT DOOR CB 25A (System power for left rear window)
• RT DOOR CB 25A (System power for right rear window)

Your best bet , take your vehicle to a qualified repair shop.
