    Sometimes there is a bad connection or an exposed wire/connection. If you hit with hand directly under the glove compartment (a little to the left) and it starts, then most likely connection problem.

    If the blower motor is intermittent I had the same problem on my '03 - remove panel under dash on passenger side - look up and see the blower motor plug - all I had to do was to wiggle the wires around and the motor started to run continuously - changed the motor cable location slightly so that stress was different on the motor wiring at the connector - been working great ever since.
