Then you will understand how insulating the suction line (in the hot engine compartment) will decrease superheat and lower suction pressure a little which equals a lower evap temperature. The dye is entrained with the oil moving through the system.

It helped mine.

 

AC in this generation is a little weak, and blend door actuators tend to fail.

 

IMO it depends upon the size of the cab, exterior color, interior color, window tint (or the lack thereof), regional climate, etc., etc., etc..

Me: Super cab with tint (35% front, factory dark rear) and even though the exterior -and- interiro is black, can EASILY freeze-out the occupants not even using the lowest temperature setting and fan speed.

Also ... HINT/TIP: Use the recirulation setting for further cooling.

Agree. My 2011 had the same setup re tint and interior color. I just thought that even with using a windshield shade in the summer, the volume and temp of the air blowing out of the dash was not impressive. Even on 100+ days, however, it would eventually get the job done, and then could be kept on a lower setting. Recirc helps a lot, particularly in maintaining a low humidity.

This is excessive.

 

Had a video of the a.c. running with the suction hose hanging from the truck towards the ground. It was a steady drip. This pic is the excess just from cracking the hose for a few minutes with the ac on. No dang way this ac system has or uses this much, oil/leak detect from the factory.

 

So, going to have it drained and refilled?

 

Bet I know the problem.

Your recirculation door is broken. I had this exact problem and from what I hear it's very common. The actuator broke the socket off the door and it gets stuck in fresh air mode. I could only get about 55-50* on a 90* day.
Take the 3 screws out and drop the fan motor. Reach up there and see if you can make the recirculation door around. it is moved and wiggles make sure you remove the broken socket piece so it doesn't fall into your fan motor.
After I rigged my door into the recirculation mode the temp get down to around 40-45* on a 95* day.

 

Im going to check the blend door. In the meantime im hoping an ac tech will chime in on the excessive leak detect spewing out of the gauge hose. Im leaning towards flushing the evaporator and condenser to see if i can reduce the amount of dye in the system.
