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.

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.
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.
multi switch is bad
You will need a scanner to turn the light off. But if you have not repaired the problem it will come right back on. There is some auto parts stores that will turn light off for free.
