Having trouble with the AC Blower. Low and medium speed work, but Hi does not. I've replaced the relay, blower motor resistor, and the Low/Medium/Hi switch in the Heater/AC control assembly in the dash. Service manual says there is a fuse located in the blower circuit between the juction box and relay. I am assuming this is somewhere in the dash. Does anyone know where the fuse is located exaclty, service manual doesn't show. I am getting a voltage drop on the brown w/ white stripe wire that controls the Hi setting to the blower motor resistor. All other wires are fine.
