How do you check a Ford Escort blower fan?
You could quickly open the hood. Locate the fan motor in the firewall, usually on the passenger side. Disconnect probably a 2 or 3 wire plug going to it and run a alligator clipped wire from the positive battery to the plugs on the fan. Touch each plug with the hot wire from the battery and see if it comes on. If it doesn’t, than it’s burned out and needs replacing.
