Currently my heater will not work in any position. My question is what and were should I be checking to make sure that I am actually getting power to the blower it self before I buy and replace the existing motor?

The plug on it.

This is the 1990 XJ blower circuit. It may apply to your '92.


The blower fuse is #5 fuse in the fuse block under the dash.

Another thing to consider is a burned up blower speed switch (behind the mode select panel).

Did u try getting power from the battery to the blower motor directly?

I haven't yet. Going to pick up a test light on my weekend and also take my dash apart and check the switch.

THose wacky engineers designed the fan switch to take full power through the switch on the high setting.
Just like headlight switch.....
