Well, the question is a bit vague. Is the flywheel to the compressor clutch turning? Does the compressor clutch engage? What exactly is it doing?
There are several possibilities here.. a bad low pressure sensor, a seized bearing in the compressor, an overcharged refrigeration system.. kinda difficult to narrow it down without knowing specific symptoms.
The 2003 Chevrolet Silverado turn signal switch is located below the dashboard, on the drivers side of the passenger compartment. The turn signal switch simply plugs in and out.
lefthand thread.
on my 2003 there is a knob on the left hand side of the dash that controls the headlites. if you turn it all the way to the left (its spring loaded) while the vehicle is on the lites will turn off.
your ac compressor could be seizing up. happened on my 2003 suburban.
In all probability you have a bad ground.
Turn the key from off to on twice and then depress and release the gas pedal 3 times quickly. This works for a 2003 Silverado.
The AC relay in a Chevrolet Silverado serves to control the operation of the air conditioning system by regulating the power supply to the compressor. When the vehicle's climate control system calls for cooling, the relay activates, allowing electrical current to flow to the compressor, which in turn compresses the refrigerant and facilitates cooling. This component ensures efficient operation of the AC system and helps protect it from electrical overload. Without the relay, the compressor would not function properly, leading to ineffective cooling.

There is a pressure switch that runs the clutch. If there is not enough freon in the system the switch will never allow the clutch to turn on.
When the system is low on refrigerant the pressure switch will not allow the compressor to turn on. You may be right on the edge so it will sometimes and other times not. You need to recharge the AC.
multi switch is bad
