alright so my heat only blows on the windsheild i cant set it to anything else need help because its startin to get really cold in Iowa

 

I have the same issue. Check the Vaccume lines. I'll repost what the other guys said

 

I haven't tried this but give it a shot. See if the Vaccume isn't pushing properly for the heater control to work.

Or look under the dash and see if any linkages have come undone

 

thanks man, this might do the trick someone said to check the vaccum lines and i wasnt sure what exactly they meant, and it was gettin to the point where i was lookin to get rid of the jeep, which we all know is a very hard thing to do, idk maybe its just a jeep thing

 

I had the same issue. Check the vacuum line that goes through the firewall through the foam around the ac lines. Mine broke off just inside the foam. Lol make sure to cover your eyes when you throw it on vent.
