Have a Bryant plus 90 ultimate heating machine... perhaps a 1992 year... the unit outside is working but the ducts throughout the house are not blowing cool air... the filter is not that dirty... I have taken the font panel off to see what I can observe and I don't hear the blower on so I'm at a loss of what to do next

It may have a door safety switch that shuts off the blower when the door is open. Close the door and cycle the unit by moving the fan switch to ON. Hear anything? Could be a bad motor, bad start or start /run capacitor or a bad thermostat. Let us know.

You will need a meter and learn how to use it.
