my heater / ac fan works only on the max setting it does not work on any of the lower settings.? my gas gauge does not work and when the tank is geting close to empty it jumps around is the gauge and fuel pump one unit ? or can it be somthing else ? thank you

you need a blower resistor. it is located on the passenger lower side of the hvac box right next to the blower motor. is sounds like you also need a fuel level sender located on the fuel pump. this is seperate form the fuel pump.
