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?
