A/C Fan Blower quit

[RangerJ]

1989 4x4 xlt 2.9 Auto. AC fan blower just quit suddenly. Have not had time to check anything yet. Need some tips on where to start to save me some time. or has anyone else had this same issue ? any help would be nice. thanks

Quickest way to diagnose it would be to disconnect the wiring connector at the fan, and shoot 12V straight into the fan and see if it works. If it doesn't, bad fan and easy fix. If it does, switch, wiring, relay, etc.

You may consider fusing the 12V hot wire you use to shoot power in just in case...

Its really hot-wiring it. I hot-wire lots of stuff... Let us know what it turns out to be.
