I have a 94 Jeep Cherokee and the Heater is not working checked all fuses and relays everything is working. Any Idea's why my heater is not working. No air blowing through the Vents at all AC nor Heater.

 

Just replace your BlowMotor.. its easy.. open the hood.. take out the windshield water thing.. and boom.. there it is.. just be careful removing fan from the motor.. because most of the store that sell the blow motors only comes with the motor and not the fan.. Take off the fan from the old motor really carefully with out breaking it. Then just put it on the new one.. mine was all loose when i put it on the new one.. because i opened the little lock too much.. so i just put superglue on it xD

 

Well I replaced the BlowMotor fuse and everytime we'd turn the Heater on it'd blow the fuse.

 

Replace the blower motor, it has a short.

 

yea.. replace the blowmotor..

 

Going to the Parts Store to get a new Blower Motor tomorrow. It had alot of tension and would hardly turn.
