I have a 2000 jeep Cherokee and I recently changed my front bumper and a couple hours later I notice that the air will only come out of my defroster no matter what setting I try and put it on the only thing that happens is hot and cold or on and off thats all.. I can feel a little air coming out of the floor and side vents and I have checked for leaks and I haven't found any.


what should I try and do do or check for!!
if you can put pictures of what I need to look for that would be very helpful thank you!!!

 

Passenger side in the bumper there is a little ball with a vacuum line going to it. You forgot to plug it back in or something.
