The ac compressor in my 2006 Chevrolet Silverado
the problem is not the compressor but the head pressure is to high and the high pressure switch is shutting it off
You say really cold while driving but on/off when stationary
That indicates that the fan in front of the condenser is not working and the high pressure gas is not converting back to liquid
2 possible items to check
fan--fan relay fan relay fuse
and excessive gas in the system
take it to an accredited ac specialist shop and have the pressures checked
At this point I am thinking excessive gas

Location of the cruise control fuse on a 2008 chevy Silverado 1500 5.3 engine
The body control module (BCM) monitors the signal circuit of the cruise control switches. The BCM relays the cruise control switch status to the engine control module (ECM) via the GMLAN serial data circuit. The ECM uses the status of the cruise control switch to determine when to capture and maintain the vehicle speed. The ECM monitors the vehicle speed signal circuit in order to determine the desired vehicle speed. The ECM uses the throttle actuator control (TAC) motor in order to maintain the vehicle speed. For further information on the TAC System, refer to Throttle Actuator Control (TAC) System Descriptionfor the 4.3L engine or Throttle Actuator Control (TAC) System Description for the 4.8L, 5.3L, 6.0L, 6.2L or 7.0L engines.
Voltage is supplied to the cruise control switch via the steering wheel control switch reference voltage circuit supplied by the BCM.

The cruise control switch contains an LED that illuminates to indicate the cruise control system has been switched ON. Voltage is applied through the ON/OFF switch to the LED when the switch is pressed. The body control module (BCM) provides the ground path for the LED through a dedicated LED control circuit. Pressing the switch again opens the switch and the lamp turns OFF.

What's your problem?I have a 2008 silverado
You need a code reader to start the process of fining the issue. The traction control is under the vehicle and is tied to the break system. Drivers side on the frame rail. If the vehicle wont start you may have a failing ECM

Slide under the front of the engine,do you see a crank sensor reading off the front crank pulley?If you see one on your model,99% of the time it's that sensor that fails.
