Clicking Sound - Therostat Knob

[bbowers]

2005 Explorer XLT 4x4

Forgive me if I use the wrong terms, but here I go.

The heat stopped working.

The knob on the dashboard that you turn to change the temperature of the incoming air --coldest (blue) to hottest (red)--has developed a clicking sound when I turn it clockwise towards heat.

If the knob was, say, a clock, the clicking sound begins when the knob reaches 9 o'clock as I turn it clockwise. The clicking continues all the way to where it's supposed to be the hottest (4 o'clock).

What's up with that? Got any suggestions?

Thanks!

Sounds like a classic case of a failed Blend Door Actuator.

Good luck with the fix.

Hope this helps out. :biggthump
