so my cherokee heater isn't working well at all.... in defrost i get the most heat but not great heat if i turn it to vent or something else i get very mild heat i felt the lines coming in and out of the heater core and they seem both pretty warm...any suggestions?

 

see if this valve is moving when you select heat on dash, also with heat selected see if the small lin to it hac vacuum. it by the pressure bottle

 

hard to tell if its moving buy myself...but i messed with it moved it in and out seems to be working alot better now.. maybe i unstuck something in it

 

cool enjoy the heat

 

lol well i wasnt worried about it so much...but didnt want to hear the girlfriend ***** tomorrow when we go to play in the snow

 

put duck tape on the vents on here side and mess with her head
