A/C issues. Need help!

A/C blows cold and then doesn't.

If I shut off the truck, and then turn it back on, it blows cold again.

What would cause this insanity?

What are your low side and high side pressures? What is the ambient temp while taking the readings?

 

[Jronguitar]

I have no idea about that.

Blend door actuator.

Blend door actuator.

Thinking this as well, fairly common issue.  Many posts on this forum about the issue.

i looked that up on here and replaced it. Synced as well.

How long does it blow cold and then quit? Or is it a sometimes cold and sometimes not until restart?

IF yo udo not have gages then take it to some one who does.
You have to determine if it is electrical control or refridgerant system at fault.

Could be one of a hundred things.
Sensors, control head, blend door, compressor, clutch, dryer, accumulator, orifice tube.
low pressure or high pressure switch, BCM, etc etc etc.

Just throwing parts it will probably end up costing you more then a decent local AC repair guy.

Just my opinion of AC systems.
