At first I was hearing a clicking noise behind the dash at start up but now I’m experiencing my heat to blow A/C at times...

To the point the only way to really get heat was to put the temperature at 84 degrees for it to only blow cool every 3-5 minutes.

Has anyone experienced this?

I have a dealer appointment Monday but I would love to hear any feedback.

If I change the temperature by press and hold, as the temperature raise you can hear a grinding/clicking noise way louder than usual.
