97 Ford Ranger - Heat & AC Blower Fan stopped working?

Hello Ford Mechanics at large, I own a 97 Ford Ranger and about two weeks ago the cab blower fan (for the Heat and A/C) started to intermittently fail. At that time when I started the truck, I would turn on the A/C, and noticed that the fan would "blast on" then turn off, then come back on, then off - next it just stopped. There are no whistles or whines coming from the fan (e.g. as if there was somthing stopping the fan blades). 1st thing checked: All fuses are good - no burnt one's found. 2nd thing checked: I purchased and replaced the inexpensive "fan resistor" switch module from the local Ford dealer here. Turned on truck, tested and it still fails - the fan resistor switch did not fix this. I know the AC is still working I can almost feel cold air coming out the vents as I cruise down the road, there is just no "fan power" to blow the air out. Is there a next good step I can try to isolate this issue? I'm fairly good with a electric DC Volt meter for a fuse box check or blower motor fan "plug going into the blower fan motor" electrical test. Any thoughts on a good next step check to fix this "no interior blower fan" condition? Best Regards, Laynester
