The intermittent operation of your 1997 Jimmy's heater fan could be due to a loose connection or damaged wiring, especially if it responds to changes in the vehicle's position. It's also possible that the fan motor itself is failing or has worn-out brushes. Checking the electrical connections and inspecting the fan motor for any signs of wear or damage is a good starting point for diagnosing the issue. If these components appear fine, the problem might lie in the switch or the relay controlling the fan.
