Heater does not work

1988 YJ-Heater does not work or at least the blower motor is not functioning. I've checked the blower motor fuse-ok. I am looking for expert troubleshooting advice of what I need to test to see what part of the whole heater system is broke. Could be electrical or mechanical? Thanks in advance.

First thing I would do is hot wire the motor to see if it is burnt out or not. If the motor runs check out the switch, then trace wires last. I would be willing to bet it is the blower motor. If it is I would replace it with the bigger blazer blower motor. Do a search over there <----- to fine heater blower upgrade info. Good luck and hope it is an ez fix. Tug[addsig]

I didn't have much heat this winter, didn't think my blower was working very well. I just used an airgun with 150 psi and cleaned it out. It made a world of difference.[addsig]
