Blower Motor Operation ∗ Low speed operation When the blower SW (Rear A/C) is moved to LO position, current flows to TERMINAL of the blower SW (Rear A/C) to GROUND, activating the RR CLR relay This causes the current to flow from the RR CLR fuse to TERMINAL of the RR CLR relay to TERMINAL to TERMINAL of the blower motor (Rear A/C LH, RH) to TERMINAL to TERMINAL of the blower resistor (Rear A/C) to TERMINAL to GROUND, causing the blower motor (Rear A/C LH, RH) to rotate at low speed ∗ Medium speed operation When the blower SW (Rear A/C) is moved to Me position, current flows to TERMINAL of the blower SW (Rear A/C) to GROUND, turning the RR CLR relay to switch on This causes the current to flow from the RR CLR fuse to TERMINAL of the RR CLR relay to TERMINAL to TERMINAL of the blower motor (Rear A/C LH, RH) to TERMINAL to TERMINAL of the blower resistor (Rear A/C) to TERMINAL to TERMINAL of the blower SW (Rear A/C) to GROUND At this time, the blower resistance of the blower resistor (Rear A/C) is less than at low speed, so the blower motor (Rear A/C LH, RH) rotates at medium speed ∗ High speed operation When the blower SW (Rear A/C) is moved to HI position, current flows to TERMINAL of the blower SW (Rear A/C) to GROUND, turning the RR CLR relay to switch on This causes the current to flow from the RR CLR fuse to TERMINAL of the RR CLR relay to TERMINAL to TERMINAL of the blower motor (Rear A/C LH, RH) to TERMINAL to TERMINAL of the blower SW (Rear A/C) to GROUND, causing the blower motor (Rear A/C LH, RH) to rotate at high speed : Parts Location Code See Page 44
