What are the part numbers? My '06 probably has the variable drive. I pushed the R134 temp scale pressure to the higher end. Once the aux fan is running, at levels 1-3 it's very cold. I'm sure it's blowing below the '60 degree setting. I don't use Auto or Max settings. Variable drive is fancy for being more efficient at different RPMs. Higher speeds help remove heat faster. The variable drive changes it's pressure stroke.

The issue I've not tackled yet is the aux fan does not turn until engine is at full operating temp. It can take a few miles before it reaches temp. During that time only speed cools it down fast. If driving in city traffic, those first few minutes can be hot. I want to change the pressure switch. Unfortunately, the system has to be evacuated.
