Sometimes on bumpy roads the heater will start out of nowhere, or when I hit a good bump it will start. The last time it worked was when I popped the hood and banged around on something with my hand then it worked. Help its cold in this Montana winter!

Check for loose wires to the blower motor. Chances are one is loose or has a bad connection.

The power connector is usually against the bulkhead on the passenger side. The ground is usually in the passenger compartment under the dash.
