Watching my pressure climb until the high switch kicked the clutch off proved I had an obstruction. I ended up recovering the system, and flushing the condenser and evaporator. The condenser was clear, but I blew some nasty stuff out of the evaporator. Orifice tube was also fairly plugged up. Went to charge after getting everything back together and my compressor clutch wouldn't engage with the low pressure switch bypassed. After some troubleshooting, I found the ground side on the clutch pigtail was melted/not making contact. I wired in a new connector and added a ground directly to the chassis for the AC clutch. AC working great. Now I'm tempted to replace the fan clutch with a heavy duty unit to improve airflow over the condenser at idle. Moving, especially on the interstate, it is freezing me out. My simple "I'm just gonna replace the HVAC controls" job snowballed into a rather involved project. But, we're functioning good now. All told, I am always reminded how much I like working on GMT800s. Only problem I have at this point is the better half keeps taking my rig to work...Parts replaced:-HVAC controller-AC clutch-AC relay-Blend door actuator-Blower motor resistor-AC clutch connector-Full AC recovery/clean/recharge (new accumulator of course)</blockquote>
