smoke coming in through ac. vents. is it the blower or resistor on blower motor.
it smells as if wires are burning. same response on ac and when heater is on. i checked everything but blower resistor on motor 0n blower.

My take on it is i dont think its from the resistor because if a blower resistor fails, you will just lose the speed of your blower. Sounds like one of your heater hoses is leaking, they pass through firewall in area you described.
