Everytime I turn my temp. dial to hot it makes a clicking noise...I googled the problem and seen it was a "heater control?" If anyone could help I would really appreciate it...Thanks

 

What year is it?

 

the hot **** controls a electric motor that moves a hot air mixing door inside the duct. not uncommon for the door or arm on the door to break with extended use. Old style and new style "blend doors" vary by age of the truck. Like ragtop said, what year? Or you can search for "blend door" on the site.

 

2004 Explorer XLT....Are they hard to change? Thanks

 

Wow I searched the site and found the heater treater thing on ebay is the way to go....I will try it and let you guys know how it turns out.....Thanks a million guys I was in the dark on this one!
