try ignition with key in and turn to number 2 and press fob button if the doors lock its worked, it f not you need to remove the battery negative and turn ignition on and lights and leave on for a few moments then turn all off again, then fit battery and do the first part again. hope this helps you.

Instrument cluster problem ! Have it rebuilt or buy a used one . GM had instrument cluster problems 2003 to 2006

I would say the torque converter is shot.

Transfer case internal problem . Not a solenoid problem .

I do not see a separate fuse for the heaters, so you have power thru the 25 amp breaker. You will, have to pull the panel up or access the mirror connector to trace power to the elements. Not sure which is easier. I have pasted all of the relevant diagrams. Likely failure modes are open heating element and failed heater switch.

take your car to the relevent work shop

no they dont cover the paint or clear coat regardless if it was never in an accident -or garage kept its whole life and theirs only 4 recalls on the truck but not for paint

Open up the other door speaker to check. I would guess it would be the darker green. It wont harm anything to try either one. It is low voltage. If one doesn't work, switch the wires.

Dies this wire come out of the dim switch??? If so, with vol meter check for voltage changes when you tuggle dim switch. If you notice changes trace wire with same color and reattach. If wire came off from the back of cluster connector you would need to get a cluster plug pin out to place wire in its proper place..

I tie them in with any dash light wire. Tape it up afterwards and it will be fine.

Is the check engine light on ? . What transmission 4L80E / 4L85-E or 4L60-E / 4L65-E 1st Gear Range Only - No Upshift Checks Causes Control Valve Body (60) • The 1-2 Shift valve is sticking • The spacer plate or gaskets are mispositioned or damaged Case (103) The case to valve body face is damaged or is not flat Shift Solenoid Valves (366/368) • Stuck or damaged • Faulty electrical connection 2-4 Servo Assembly (13-28) • The apply passage case is restricted or blocked • Nicks or burrs on the servo pin or on the pin bore in the case • Fourth servo piston is installed backwards 2-4 Band Assembly (602) • The 2-4 band is worn or damaged • The band anchor pin is not engaged

Linkage, synchronisers,..You need tranny repair!!!!!!

Sounds like you are losing wheel speed signal when under hard turns. This is commonly caused by the harness at or near the wheel speed sensor has a bad connection of there may be a break in the wiring that intermittently loses signal to the ABS module and causes the anti-lock function to happen, (loss of wheel speed is like wheel skid as far as the ABS module is concerned) It is usually necessary to have a scan tool to monitor the data and read codes on the ABS system. You may have to take vehicle to shop that is capable of diagnosing the problem.

suggest checking cable on accelerator throttle arm in engine bay where it connects from cruise control to accelerator throttle arm on engine. Thinking if it is loose it may get looser when hot. Check connectors on electronics in engine bay on cruise control. Check sensor for speed. Is it ignition maybe a scotch lock connector that expands with heat and cruise control looses sensor for igition pulses. How does it sense speed ? Is it magnets on the drive shaft maybe the Hall efect transducer is close to exhaust pipe under car and is being affected by heat. Is it front wheel drive ? check for a pulse sender on speedo cable in engine bay maybe this is getting cold. Check cruise control cable is oiled adequately in cable sleeve . check vacuum connector is ok in engine bay also ?

If I remember correctly...18-24 inch pounds.
