Why is there no air blowing out of the vent of my Jeep Grand Cherokee?

Answer by  CraigMpls (55)

Can you hear the vent blower fan running? If not, the blower has either blown a fuse or the motor has a broken wire or has burned out. If you can hear the fan running, is there air comming out of other vents? If so, the vent tubing is blocked.

There can be a few reasons for it not blowing and you can elimante them step by step without tearing the whole dashboard apart. First of all check you fuse in the panel for a blown fan moter fuse, if this is not it then check the vents for blockage. If this is not it replace the blower motor.

Check to see if the vent is open. Grand Cherokees have two ways the vents can be adjusted. Check the fuse or relay for the heater switch/fan.

no air is blowing out of your vents on your jeep because the fan in it has died and you need to buy a new one
