Default heater blower suddenly inoperative

It'* Very Cold outside, and I have very little heat as the blower, (which worked very well with last use, no strange noises etc...) now will not run on any setting..
has been this way all week now.
Car is a 93 SE, with manual heat/A-C controls.
I now have a head/chest cold, and need some relief, in the heat dept....

Checked all fuses under dash,with an ohmmeter, they're good. The engine bay fuses are also conducting. I don't know what, or where to check next. Search, only brings up a newer model with electronic controls, for this issue.

Is there a flow chart for this problem?

Any help would be truly appreciated

Unplug the electrical connector at the blower motor (on the firewall). Plug a 12V test light into the connector, turn the controls so the blower should be on high. If the test lamp illuminates, you need to replace the blower motor. It is about $50 and a pretty easy r&r. Lots of times when the brushes and commutator in the blower motor have worn down, just a good whack will start it going again. Maybe this will work for you until warmer weather.
