So my 97 Cherokee country, the Ac started blowing out only the defroster vents the other day, both the cold and heat work, as well as it blows out on all 4 fans speed settings. So I took it to tire kingdom, they hooked it up to their Ac machine, told me I had a broken Hose, replaced it but problem stayed. So now I'm out 119$ and still no fix, please help.

 

The vent flaps are vacuum-controlled. I'd look for a problem with the control switch, vacuum lines, or actuators.

 

Vacuum leak.. check the lines near the battery tray.

 

x2 van line/ball issue. Check these spots out

 

How about this?

 

I just found a vacuum leak that controlled my vent flaps. There is a harness in the back firewall that has three hard lines in it. the bottom one was cracked, so I put a touch of glue on it and wrapped it in electrical tape. exactly as it is in the the diagram. Works perfectly... just hope it lasts

 

Better.

Oh no worries. I figure as long as I'm not trying to claim it as my own then its fair game on here.. Obviously credit to the OP when it can be done.. BTW, Check out this picture I made.

 

LOL.

 

I just hopped on to find out the fix for this exact problem. Thanks everyone who contributed.
