SOURCE: where is the coolant temperature sensor located in a 2003 yukon

It is best to allow the engine to cool down for about 3-hours before starting this job. This is for safety and convenient reasons. It also helps to minimize the loss of coolant. Coolant draining into the environment should be avoided.
After the engine cools down, disconnect the negative terminal of the battery.

Location: The Denali's engine coolant temperature-sensor is located (threaded) into the cylinder-head just above the spark-plug. It is good thing to remove the spark plug wire in the coolant temperature-senor's immediate area. This will allow more room to work it out.

It is removed by first undoing its electrical plug, and then using a deep socket with wrench to loosen the coolant temperature-sensor.
Once done, verify that the electrical connector is replaced in its proper location. Then coonect back the negative battery terminal.

SOURCE: How do I remove and replace the power side mirror

2003 GMC Yukon - My power mirrors stopped working.... all fuses have been checked and they are all good. Any ideas? These are the power folding mirrors. The function that allows you to fold them in for car washes etc still works.... they just will not adjust when you change drivers, or when you try to adjust them with the controls. Any ideas would be appreciated!

SOURCE: 2003 Yukon Denali has Service ride Control Warning..wat to do?

Hi Jose:
The first place to start is to have Ride Control Module scanned for trouble codes, this requires a high end scan tool. Most common problem is the air compressor in the rear or a height sensor. Here is how the system works.

Automatic Level Control Description and Operation
The RTD system is bi-state real time damping system. The Suspension Control module controls the suspension damper solenoids and suspension position sensors, along with parts of the automatic level control (ALC) system and electronic variable orifice (EVO) power steering system.

The Automatic Level Control system consists of the following:
• Suspension Control Module
• Compressor/Leveling Module
- Air Pressure Sensor
- Exhaust Solenoid
• Compressor Motor Relay

The objective of the Automatic Level Control System is to provide constant ride height at all load conditions. The Suspension Control module monitors body-to-wheel height, and vehicle speed.

The Suspension Control module will use the rear body-to-wheel displacements and vehicle speed inputs to keep the rear trim height of the vehicle at its desired level.

The electronic suspension control (ESC) system is bi-state real time damping system. The ESC module controls the suspension damper solenoids and suspension position sensors, along with parts of the automatic level control (ALC) system, if 1500 series.

The ESC system consists of the following:
• The ESC module
• The compressor/leveling module, if 1500 series
- The air pressure sensor, if 1500 series
- The exhaust solenoid, if 1500 series
• The compressor motor relay, if 1500 series
• The steering handwheel speed/position sensor
• The suspension damper solenoids
• The suspension position sensors

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.
