Hows your thermostat?

 

just replace it not long ago and also my temp gauge is good also the car get to it normal reach temp so there is no error codes ??????? i am so lost anyone

 

The doors in the vents might be stuck.

 

sounds like maybe your blower might be back? Did you check the heater core?

 

i got my heater core flushed still made no difference i will check the door

 

Have it run on a real vagcom and check the HVAC system for codes. There is also test procedures you can run with the vagcom. Sounds like a flap valve is stuck and air is not being directed over the heater core.

 

I believe the AC comes on to control the humidity of the air so your windows dont fog up.
