Hi. Suddenly my vents do not blow any air/heat, although the lights/buttons on the temperature control panels operate, etc. I replaced all fuses that could possibly be linked and still, no air. I even replaced te Final Stage Unit (Blower Motor Resistor) and still, no air. Any other suggestions on what to check out?

The final stage has been replaced and still no air flow usually means the fan motor has got a bad spot on the commutator and needs replacement as well. Be sure the wiring connector is not the issue here, I have had that happen to me.
