Removal and Installation
1. Disconnect battery ground cable.
2. Remove A/C control.
3. Remove the knob from the heater blower motor switch by placing a small screwdriver between the knob and A/C control. Pry with the screwdriver and pull the knob from the heater blower motor switch.
4. Pull the A/C control through the opening far enough to allow removal of the electrical connector.
5. Remove the electrical connector from the heater blower motor switch by lifting the snap-lock retainer with a screwdriver. Pull on the connector until it separates.
6. Remove the hex-head screw which attaches the heater blower motor switch to the bracket and remove the heater blower motor switch.
For installation, follow removal steps in reverse order.
NOTE: When the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the powertrain control module (PCM) relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 miles) or more to relearn the strategy.
