1982 Jeep CJ7 HEATER MOTOR DONT WORK AND ALL FUSES ARE OK

Hi rubdaz,

Thank you for the donation.

If the problem is new, give the blower motor housing some banging and if motor starts, it is failing and due for replacement.

If motor does not run, unplug the motor wire connector and test for resistance across the motor terminals, no continuity means the motor is bad.
