Test L: The Blower Motor Is Inoperative - Manual Climate Control

PINPOINT TEST L: THE BLOWER MOTOR IS INOPERATIVE - MANUAL CLIMATE CONTROL

Normal Operation
Under normal operation, the blower motor relay coil receives ground through circuit 57 (BK). The blower motor relay coil receives voltage from the function selector switch through circuit 249 (DB/LG) if any position but OFF is selected. The function selector switch is supplied voltage through circuit 1812 (BN/WH). Voltage is supplied to the relay switch contact through circuit 364 (BK/LG). When the relay coil is energized, voltage is delivered to the blower motor through circuit 371 (PK/WH). Ground for the blower motor is provided through circuit 261 (OG/BK) from the blower resister or the blower switch (HI). The blower resister and blower switch is grounded through circuit 57 (BK).

This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Wiring, terminals or connectors
- Blower motor
- Blower motor relay
- Function selector switch
