Take it to an Autozone, or similar, and have the alternator tested (they can do it with the alternator in the car).Something to consider, when running air and other accessories, it's pretty common for the voltage to drop slightly when idling. Just have it tested for piece of mind.

If the sending unit was connected and grounded, I would guess the gauge in the cluster is faulty.

your crank sensor may be bad but if its turning over slow you may check the charge in your battery as well as your connections for corrosion

you have to drop the tank to remove the sending unit, there is a ring that holds the unit in place.

My first guess would be not enough freon. What are the gauge readings ?

Hi Bratton, Check all the connections to the system and the speakers. It could be that you have a speaker or speakers that are paralyzed. this can happen if the volume has been pushed up too high and the speaker(s) becomes frozen. Regards John

Grab the dashboard bezel that goes around the radio and the gauge cluster with your hands, and pull it toward you to release the clips that hold it in place. Then unplug the wiring to the headlight switch and any other accessories on the panel (which change depending on what model of Sierra you own), using your hands. Pull the bezel away from the dashboard, and put the Sierra's transmission back in "Park."

4Place the dashboard bezel face down on a work surface. There are two tabs on either side of the dashboard bezel holding the headlight switch in place. Use the flat-head screwdriver to gently pry these apart one at a time, then pull the switch out of the bezel. Be careful, because depending on how brittle your dashboard is, you can break these tabs fairly easily.

5Push the replacement switch into the dashboard bezel. Then put your foot on the brake again, shift the truck into the lowest gear, and reinstall the wiring to the bezel using your hands. Push the bezel onto the dashboard to secure the clips, then put the truck back in Park and turn off the ignition

Hi there:You will need to have the system scanned for codes. Each shock has a sensor there is a ride height sensor as well. The computer will give a code which will show what is the cause. use a scan tool to access the suspension module to get trouble codes.The service ride control is related to the level control air shocks in the rear of the vehicle. A scan tool pulling fault codes would help isolate the cause. It is almost always the exhaust solenoid in the pump assembly but it can be other issues. We would need to know a fault code to go further. I suggest to check this TSB from GM in THIS LINKHope 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, have a nice day.

tap on the resivor if that doesnt fix it replace the sensor

you have 2 of them on that vehicle and both of them are located under the intake manifold.
