Question about 1983 Jeep Cherokee
80 cherokee defroster doesn't work will not blow any air blower motor is ok
It could be one of a couple of things. First, make sure all of the vacuum lines are good. The blower motor makes the air move, but its vacuum that sends it where you want it to go. The vacuum lines start at the control head and go to the different blend air doors. Either go under the dash, if you can access them that way, or remove the control head from the dash to inspect the lines. Make sure your engine vacuum lines are good also. If all that checks out, check the air duct tubes. They could very well be cracked and torn from many years of use.
