Is there continuity?  

YES -Repair short to body ground in the wire(s) between the heater control panel and the mode control 
motor. 

NO -Substitute a known-good heater control panel, and recheck. If the symptom/indication goes away, 
replace the original heater control panel. 

DTC 12: A PROBLEM IN THE BLOWER MOTOR CIRCUIT 

1. Check the No. 12 (40 A) fuse in the under-hood fuse/relay box, and the No. 14(10 A) fuse in the under-

dash fuse/relay box. 

Are the fuses OK?  

YES -Go to step 2. 

NO -Replace the fuse(s), and recheck. 

2. Connect the No. 2 terminal of the blower motor 2P connector to body ground with a jumper wire.

3. Turn the ignition switch ON (II). 

Does the blower motor run?  

YES -Go to step 4. 

NO -Go to step 17. 

4. Turn the ignition switch OFF.  

5. Disconnect the jumper wire.  

6. Disconnect the power transistor 4P connector.  

7. Check for continuity between the No. 2 terminal of the power transistor 4P connector and body ground.

Is there continuity?  

YES -Go to step 8. 

NO -Check for an open in the wire between the power transistor and body ground. If the wire is OK, 
check for poor ground at G501. 

8. Connect the No. 2 and No. 4 terminals of the power transistor 4P connector with a jumper wire.

9. Turn the ignition switch ON (II). 

Does the blower motor run at high speed?  

YES -Go to step 10. 

NO -Repair open in the BLU/BLK wire between the power transistor and the blower motor. 

10. Turn the ignition switch OFF.  

11. Disconnect the jumper wire.  

12. Disconnect the heater control panel 30P connector.  

13. Check for continuity between the No. 18 and No. 19 terminals of the heater control panel 30P connector 

and body ground individually.

Is there continuity?  

YES -Repair short to body ground in the wire(s) between the heater control panel and the power 
transistor.

NO -Go to step 14. 

14. Check for continuity between the following terminals of the heater control panel 30P connector and the 

power transistor 4P connector. 

30P: 4P: 

No. 18 No. 1 

No. 19 No. 3

Is there continuity?  

YES -Go to step 15. 

NO -Repair open in the wire(s) between the heater control panel and the power transistor. 

15. Reconnect the heater control panel 30P connector.  

16. Test the power transistor (see POWER TRANSISTOR TEST ). 

Is the power transistor OK?  

YES -Check for loose wires or poor connections at the heater control panel 30P connector and at the 
power transistor 4P connector. If the connections are good, substitute a known-good heater control panel, 
and recheck. If the symptom/indication goes away, replace the original heater control panel. 

NO -Replace the power transistor. 

17. Disconnect the jumper wire.  

18. Disconnect the blower motor 2P connector.
