Removing
1. We prepare the car for work (see "Preparing the car for maintenance and repair").
2. Remove the left overlay of the instrument panel console (see "Dashboard - removal and installation").
3. Disconnect the wiring harness block from the additional resistor of the heater electric fan.
4. Using a Phillips screwdriver, unscrew the self-tapping screw for mounting the additional resistor (shown on removed heater).
5. Remove the additional resistor from the heater.
Examination
1. By external inspection, we make sure that the spirals are intact, that there is no charring or other damage.
2. With a multimeter in ohmmeter mode, we check the spirals of the additional resistor for an open circuit. If a break is detected in one of the spirals, we replace the additional resistor.
Installation
We install the additional resistor in the reverse order of removal.
