No ac/heat blowing from vents 07 Mustang Gt
Hey everyone new to this so heres my problem . I have tried to fix this damn ac myself. Replaced the fuses, and relays got a new blower motor resistor and recently just got a new blower motor to see if that was the problem. AC turns on sometimes but if i put the setting past 3 it turns off or doesnt turn on at all. With summer heat coming fast any help is appreciated.

Might want to have a shop diagnose it for you. That will cost you but then you'll know for certain what to replace instead of just throwing parts at it.
When you say AC turns on but then cuts out, are you talking about the blower motor or AC clutch/compressor?
Do you have an AC Manifold Guage set? If the refrigerant is low it would cause the system to shut down when it can't hold the required pressure in the system.
