BLOWER MOTOR CIRCUIT
CIRCUIT DESCRIPTION
The blower motor is operated by signals from the A/C amplifier. Blower motor speed signals are transmitted
by changes in the Duty Ratio.
Duty Ratio
The duty ratio is the ratio of the period of continuity in one cycle. For example, if A is the period of continuity
in one cycle, and then B is the period of non±continuity.

(a) Turn the ignition switch to the LOCK position.
(b) Disconnect the negative (±) terminal cable from the bat-
tery, and wait for at least 90 seconds.
(c) Disconnect the connectors from the airbag sensor assy
center and the horn button assy.
(d) Measure the resistance between D+ and D± of the con- nector ºEº.
