A/C unit on 2008...

A/C unit on 2008 F-150 blows hot. I have blown the dye into the a/c line. No leaks found. The compressor is kicking off and on normally. When I shut the engine off I can hear bleed of towards the front of the truck. Line shows to be fully charged.

Mechanic's Assistant: How old are the hoses? And what driving conditions do you most often encounter?

Original lines from 2008 as far as I know. Normal central Texas driving conditions.

Mechanic's Assistant: Are you fixing your F150 yourself? What have you tried so far?

I have uses the coolant with dye in it to detect leaks. I have also fully charged the system.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

No I don't think so.

I do not hear the actuator moving. Should it be obvious
Customer reply replied 1 month ago
Could the actuator door be sticking. It stopped cooling after I went from hot to cold.

I replaced the temp blend actuator and it did fix the problem with the cooling g system. I still hear what sounds like air escaping from the lines for about 20 seconds after the engine is off. Not sure if that is normal?

thats totally normal, the pressure relief
