First of all I have had an ac man check it and it shows to be nothing wrong with the ac sys.
Now when I got this vehicle the heater did not work so I went one winter without it and the ac worked fine and cooled good.
Now the following year one day I was missing around with the controls and the heater started working good blowing hot air,
but then shortly about 10 min later the clicking noise starts and I shut the heater off. Now my ac does not blow cold and I think the heater still works. Can you give some input on this perhaps it is that actuator problem?
