Blower Power Transistor Test (Manual A/C with Navigation)
Blower Power Transistor Test
Removal
1. Glove Box
1. Remove the bolts (A).
2. Remove the glove box (A).
2. Passenger's Heater Duct
1. Remove the passenger's heater duct (A).
3. Driver's Dashboard Lower Cover
1. Remove the driver's dashboard lower cover (A).
4. Dashboard Subdisplay Visor
1. Remove the dashboard subdisplay visor (A).
5. Center Lower Panel
1. Remove the center lower panel (A).
NOTE: Take care not to scratch the center console panel or the related parts.
6. Audio-Navigation Unit Assembly
NOTE:
* Lay a workshop towel under the parts when working on them to protect the face panel from scratches or other damage.
* Do not work in a dusty or dirty place.
* Discharge static electricity from your body before and during the work.
* Do not touch the circuit board(s) with your bare hands.
* Do not work with dirty hands.
* Do not touch the terminal connector of the flat plate cable with your bare hands (If you have touched it, wipe it off thoroughly.).
* Eject the discs before removing the audio-navigation unit to prevent damaging the CD/DVD player's load mechanism.
* If you are replacing the audio-navigation unit, write down the audio presets (if possible), then enter them into the new audio-navigation unit.
* When the audio-navigation unit is replaced or disconnected, do the Map Matching. This part of the initialization matches the GPS coordinates with a road on the map screen. To do this part of the procedure, make sure that the navigation system displays a map, and drive the vehicle on a mapped road shown on the map screen. Do not enter a destination at this time. When the name of the current road you are driving on appears at the bottom of the screen, the entire procedure is complete.
1. Remove the bolts (A).
2. Disconnect the connectors, then pull out the audio-navigation unit (A).
7. HVAC Control Unit Assembly
1. Pull the HVAC control unit assembly (A).
2. Disconnect the connector (B).
8. Power Transistor
1. Disconnect the connector (A).
2. Remove the power transistor (B).
Test
1. Power Transistor - Test
2-door
4-door
1. Measure the resistance between terminals No. 3 (2-door) or No. 2 (4-door) and No. 4 of the power transistor. It should be about 1.5 kOhms.
* If the resistance is within the specifications, go to step 3.
* If the resistance is not within the specifications, replace the power transistor.
NOTE: Also check the blower motor. Power transistor failure can be caused by a defective blower motor.
2. Reconnect the power transistor connector.
3. Connect HVAC control unit connector terminals No. 17 and No. 22 with a jumper wire.
4. Turn the ignition switch to ON (II).
5. Check that the blower motor runs.
* If the blower motor does not run, replace the power transistor.
NOTE: A faulty blower motor can cause the power transistor to fail. Before replacing the power transistor, check the blower motor for binding, and replace it if necessary.
* If the blower motor runs, the power transistor is OK.
