temperature control knob?

Does anyone know if the temperature control knob is electronic or manual? Its a 2001 tj with AC. where can i find a replacement?

The long story, i was trying to remove the knob and now i can only get full blast heat. turn the knob to the cold (blue) side and still get heat. Not very good for the desert summer. i need to fix this soon......

It's a manual knob that controls the temp via a stiff control wire. Check that the control wire that controls the heat valve up above the passenger-side footwell is still connected to the lever it controls. Maybe by jiggling the knob it allowed the control wire to come off.

My 2004 Sahara had a similar problem.....the inside of the know broke and would spin and not turn the controls to the ac. Check the metal bracket on the inside of the knob and glue it in place with gorilla glue. Half the inside of my knob is missing but the gorilla glue worked wonders.

Call the dealer for a knob. Picked up one from the dealer for $8.

not on my 2001. The stiff wire is now an electric motor that controls the flap between hot and cold incoming air. you turn the knob on the dash from red to blue and this motor adjusts the air deflector flap from the heater core to fresh air.

The motor is held in place by 3 5/16" hex screws. I was able to take off the motor, and manually move the flap to get me some cold air. I don't have time to properly repair it because i'm still unpacking, but i'll post back up when i get around to it.
