HEAT

2008 Ford Explorer • 58,000 miles

When I turn the dial to heat, it's starts making a clicking noise in the dash, and only cool air comes out. I can turn the dial back to cool and the air conditioner works good. And no clicking noise.

It sounds like you mode door temperature actuator is worn out causing a clicking noise when commanded to move. The gears inside wear to the point the gears will jump pass each other causing a clicking noise.
Does your vehicle have dual temperature controls (can adjust temperature for driver and passenger independently)?
What side of the dash does the clicking noise come from, driver or passenger side?
Talk to you soon, TY
