My defrost works and air blows out the passenger foot area through a hole but my vents don't work. I've read this is a vacuum leak? Where along the vacuum line should I look first? Also, the blower motor doesn't blow air until I put the climate control setting on high, and my defrost blows heat even when it is turned off in the summer.. any ideas?

the blower issues may be the speed selector resistor and the vents issue are the vacuum hoses. They are located behind the rocker swicth panel and are connected to the vent selector switch.

Poke your noggin up under there. You'll see what you need to do. Easy. Then trace the vacuum lines connected to the ball up towards the firewall. They're very prone to getting eaten up by battery acid where they pass under/beside the battery.

open your Jeep's glove box and behind that you will see the a/c vacuum plug. verify that you dont have an air leak. the heathet door sometimes dont close all the way. if that is the case you can adjusted.
