Using a wire diagram for a '70 Corvette, check continuity between wire terminations. It's most likely a bad connection somewhere, be it a wire or a terminal. Hope that helps!-ku2002
Replace the blower motor resistor.
To change the heater fan on a Seat Leon, start by disconnecting the battery to ensure safety. Remove the dashboard panel or access cover to reach the fan assembly, which is typically located behind the glove compartment. Unscrew the fan motor from its housing, disconnect the wiring harness, and replace it with the new fan. Reassemble the components and reconnect the battery to test the new fan.
