I have a 1995 GMC Jimmy with 187,100 miles on it. The heater kicks off and on while driving. When I start the vehicle it is hit or miss whether the heater will work or not. As I drive, the heater will kick on after roughly 5 minutes.

Do you mean the fan starts and stops? Or the heat comes and goes? If it's the fan it could be the switch or more likely the ground on the fan housing itself. They get corroded and act that way. If it's the ground you can replace it with a wire from the motor plate to the chassis. If it's the power connection just clean the contact good and replace the connector on the wire.
