Service Tip
Although your multi-meter might have a function to check continuity by giving beep
sounds, use the range of your multi-meter to check resistance (ohm) when you check
continuity between the terminals B and D. This is because your multi-meter may
determine there is a malfunction due to the combined resistance of the resister and
coil between the terminals B and D.

Service Tip
Blower motor can be inspected by directly supplying battery voltage. Connect battery
positive voltage to blower motor terminal A, connect terminal B to ground, and then
verify its operation. It should be operated the same as Fan switch is at its position 4.
