They need to check the mode door actuator. This is what changes the blend door from hot to cold. The engine fan will run as long as the ac is on, to keep the condenser cool.

I have had alot of trouble with after marker actuators. Do you know if they used a factor replacement? Did they check to see if the blend door was broken?

Customer: replied 2 months ago.
I don't know if they used factory part but I'll ask about the blend door. Thank you

If you do not mind, can you ask them what the high and low side pressures are for the ac system as well?
