Heater Air Blower

Measuring the motor speed and the fuel delivery quantity can only be done by measuring the current.

• Remove 16 Amp main fuse. Open footwell outlets and pull heater flap lever fully back.
• Disconnect cables from heater air blower. Connect ammeter and battery as shown.

For a 12 Volt battery the current input is 6.5 to 7 Amps. Deviations in readings are due to defects in the heater air blower.
