check your fuel pump relay and your ignition switch those numbers you gave for voltage are not right, please recheck that you have a ground and 12volts at the pump while cranking please rate -jeff

This is an easy solution. Remove the glove box door strap and remove the glove box door by letting it drop towards the floor while supporting the door and it will release from the dash. Then you will see the blower motor housing along the firewall on the interior. You will just need to unplug the wires to the motor and remove a few screws and carefully remove the motor with the blower cage attached to it. Then just reverse the process and you will be good.

I'd replace blower resistor, usually found under hood on firewall on passenger side, or on duct work, inside under dash on passenger side,close to blower motor.

If you bypass the resistor pack and connect the motor directly to the fused 12v supply then the fan should run at maximum speed. If so, it's the resistor pack that's blown: a very common fault on a huge number of makes and models.
