Front A/C issue

[01Konvict]

I would guess the 06 denali has electric fans and that the fan for the AC isnt working. I did the efan swap and my AC fan relay was bad. Replaced the relay and fan worked then AC started cooling. I would start with that symptom first then look into AC parts.

Just for something cheap to try-

Hose off your radiator and condensor fins. Hose out between them too. It's good maintenance anyway.

The condensor relies on airflow through its fins to cool properly just like a radiator does. If airflow is reduced by crud then it can't work.

have the system evacuated and check to see if the orifice tube is clogged up

I did a search before I resurrected the thread and saw this efan, but have no clue what it is. My next course of action is to hose out the cooler, rad, and condenser as I do know that can inhibit the A/C, but are there 2 condensers on a dual zone equipped vehicle? I know there's only one compressor so...

And the secondary fan kicks on as expected.

There's only one condenser but 2 evaporator cores
