Hey all, I have a 1999 millenia 2.5 and when ever I set the auto climate control for heat, the ac turns on also. is this normal? thoughts?

 

this is normal. climate control mixes heat and a/c. if you want heat only, press the a/c button twice, and the a/c will turn off. then you can use the center temp control. where the heck are you that you need heat now?
