download 2005 – 2011 Toyota Tacoma HVAC Blower Motor Only Operates On High. Some Tacoma vehicles may experience a condition where the blower motor
only operates on High and all other blower speeds are inoperative. The
blower motor resistor and resistor connector have been updated to
address this condition. Repair Procedure 1. Verify the blower motor only
operates on High. NOTE If the blower motor operates on any speed other
than High and the connector is NOT discolored this TSB does NOT apply.
2. Disconnect the negative battery cable. Repair Procedure (Continued)
3. Disconnect the blower motor resistor connector and remove the blower
motor resistor. NOTE Steps 4 – 8 will need to be repeated for each of
the 4 wires on the new connector pigtail. Figure 1. . 4. Cut the old
connector from the Harness. A. Use the new wire lead as a guide for
proper length. NOTE If the length of wire removed is not approximately
the same length as the new piece, the following problems may develop: •
Too short – tension on the terminal, splice, or the connector, causing
an open circuit. • Too long – excessive wire near the connector, may get
pinched or abraded, causing a short circuit. Figure 2. . 1 Existing
Terminal 2 Cut 3 New Terminal with Lead Repair Procedure (Continued) 5.
Strip insulation from wire on the harness and replacement terminal lead.
Start stripping at least 8 mm (0.31 in.) to 11 mm (0.43 in.) away from
the end of the existing harness at vehicle side and also from the end of
the repair wire. NOTICE Take care not to damage the wire when stripping
the wire harness lead. After ?nishing the operation, visually inspect
the wire. If there is any damage, perform the operation again.
