Getting the Wheeling Fever
What controls the A/C idle control speed? Isnt there a switch that increases the idle when the A/C is on?
If so, where is it?
I dont think my truck is ideling fast enough
when stopped and in "Drive" such as at stop lights. My A/C compressor kicks off, but if i give it some gas and increase
the RPM's it will kick back on.

Also, where do i ramp up the "global" idle speed?
Where is the idle air control valve?

IAC valve is the valve that sticks out at 3:00 looking down at the engine. It is a pintle with a rotating stepper motor that retracts allowing air to go around the throttle blades.


The Idle air control is set through a procedure you can find here:
