1999 jeep cherokee heater question

1999 Jeep cherokee 4.0L
Heater A/C only blows through the defroster no matter what position the switch is in.
It does produce Hot and or cold air as directed just out the defroster.
Any help appreciated.

Sounds like cable is off or broken. (This is just my opinion.)

That's the default position when something breaks
I don't know if this is vacuum or mechanical operated, but I suspect vacuum and there is none

Loose/broken/crimped hoses or some other interference is my first choice for a likely suspect

I have developed a solution for the jeep grand cherokee heating problem. The usual problem involves the breaking of the blend doors. My solution is strong, easy to install, and it definitely beats paying the dealer $1800!! For more info please email me: jeepheaterfix at yahoo
