a/c not cooling real good, and also heater not heating up. on 2006 Kia Sorento

a/c was doing fine until wife turned on defroster, since then a/c has not been great. also the levels are good on freon

Asked by for the 2006 Kia Sorento
make sure the cooling system is working corrctly as this will directly effect the operation of the ac.
how do you know the fren is correct?? pressure readings never indicate freon level.

Ok, pressure reading is ok. The cooling system is working fine, not over heating. I think it is the temp. actuator (Manual).Thanks for the reply.
pressure readings may be ok but that does not mean there is enough freon in the system. you still need to have amount verified and a leak test done to confirm.
the cooling system may be low coolant, bad thermostat or clogged heater core.

Thanks, I checked blend door actuator,, it is not working...stuck in 1 position.
