hi there a couple of days ago this started my 86 244 aw 70. when i shut off the vehicle with the radio on as the motor stops, i can hear elictrical noise in my speakers maybe like the alternator winding down . it lasts about 2 seconds. any one experienced this before? thanks for everything. :-}

also my resistor in the blower is shot. i was thinking about relocating it into the ductwork , thus splicing the wires outside the blower case and not having to go in there the motor is quiet. living in florida i use the air conditioning like nene months a year and the heat maybe ten times what do you think.
