The following components, when used in combination, determine
the blower speed:
The blower resistor consists of 3 resistors located in the same
housing.
With the blower switch in LO, the following actions occur:
| • | The blower circuit uses all 3 resistors. |
| • | The blower motor runs at the lowest speed. |
With the blower switch in M1, the following actions occur:
| • | Two of the resistors are in use. |
| • | The blower motor runs faster. |
With the blower switch in M2, the following actions occur:
| • | Only one of the resistors is in use. |
| • | The blower motor runs even faster. |
With the blower switch in HI, the following actions occur:
| • | None of the resistors are in use. |
| • | The blower motor runs at maximum speed. |
