1992 Stanza: heater mode door buttons will not change modes; heat only comes from floor vent or floor/defrost; could problem be a fuse, connector, or is mode door motor replacement needed?
When you push mode door buttons nothing happens; all other parts of heater and A/C
work fine; I assume if motor needs replacing I will have to go through the panel that
includes removing the radio to get to the motor and electrical connector. Hope problem is
a fuse or ground wire. Could that be possible?
