Chevrolet Tahoe Air Conditioner Switch

Actuator Is Working (both). I Turn The Power Switch On For Rear A/c I Hear Click But No Function.

Rear A/c Works Intermittently. When The Rear Air Does Come On The Air Is Cold. I Replaced The Switch But That Did Not Solve The Problem....

Dash Switch Works But Front A/c Does Not Go On? I Was Told The Plug To The A/c Is Fried? Suppose To Be A Common Prob With These Vehicles.

Clutch Cycles On & Off Even With Air Cond. Button In Off Position. Seems Odd. Stopped By Disconnecting Switch On Accumulator But Would Like...
