Driver's under dash fuse/relaybox, fuse # 4 ( 7.5 A ) Hot when ignition switch is turned ON.
Passenger underdash fuse/relay box fuse # 14 ( 20 A) Hot at all times.
If the passenger heater is working correctly, this is not a problem with the fuses or relays as they uses the same circuit.
Check the wire connectors under the seats for proper installation/connections.
It could be a faulty switch.
