To replace the heater core on a 1984 Jeep CJ7, first disconnect the battery and drain the coolant from the radiator. Remove the dashboard and the heater assembly, which typically involves detaching the control cables and electrical connectors. Once the assembly is out, unbolt the old heater core from its housing and replace it with the new one. Reassemble everything in reverse order, ensuring all connections are secure before refilling the coolant and testing the system.

How do you change a motor blower on a 1984 Jeep CJ7 if this information is not in your Jeep manual?
I replaced the heater core on my 1982 Jeep CJ7 about 5 years ago, and I believe you would have to go through the same procedure to replace the blower motor, since they are housed together. Bare with me on the details,but; The blower motor is housed in the heater/ventilation box (the plastic venting system under the dash). The motor's back end protrudes into engine compartment through the fire wall under the battery tray. Disconnect the blower motor's electric wire and heater hoses from the motor and firewall, you'll find them under the battery tray. To replace the motor you'll need to take apart the heater/ventilation box, I believe you'll have to remove the entire unit to do this. The plastic heater/ventilation box is bolted to the fire wall, unbolt it from the fire wall (nuts on the firewall side) and disconnect the heater/vent cables from the box and it should come out from under the dash. The box has screws around the perimeter unscrew them and it should come apart revealing the motor, fan and heater core. You need to remove the fan from the motor shaft. Good luck.
