OK, After I ran the self diganostic test on the AC (it will only blow burning hot air, no matter what temp you set it on), the codes that came up are 024, 025, 053, and 051. Can you tell me what those are? THanks so very much.
Do you
have the same problem?

DTC 024/B1249: BLEND DOOR FAILURE
Turn ignition off. Disconnect Remote Climate Control (RCC) module 26-pin harness connector C228. Connect a fused jumper wire between RCC module harness connector C228 terminals No. 22 (Orange wire) and No. 11 (Red/White wire). Connect a second fused jumper between RCC module harness connector C228 terminals No. 21 (Dark Blue/Light Green wire) and No. 8 (Black/White wire). See Fig. 3. If temperature blend door actuator drives clockwise, go to next step. If temperature blend door actuator does not drive clockwise, go to step 3.
Remove jumper wires. Connect fused jumper wire between RCC module harness connector C228 terminals No. 21 (Dark Blue/Light Green wire) and No. 11 (Red/White wire). Connect a second jumper wire between RCC module harness connector C228 terminals No. 22 (Orange wire) and No. 8 (Black/White wire). If temperature blend door actuator drives counterclockwise, go to step 8. If temperature blend door actuator does not drive counterclockwise, go to next step 9.
Disconnect blend door actuator 8-pin harness connector C289. Measure resistance between ground and RCC harness connector C228 terminal No. 21 (Dark Blue/Light Green wire). If resistance is more than 10 k/ohms, go to next step. If resistance is 10 k/ohms or less, repair short to ground in Dark Blue/Light Green wire between RCC module and temperature blend door actuator. See WIRING DIAGRAMS. Recheck system operation.
Measure resistance between ground and RCC harness connector C228 terminal No. 22 (Orange wire). If resistance is more than 10 k/ohms, go to next step. If resistance is 10 k/ohms or less, repair short to ground in Orange wire between RCC module and temperature blend door actuator. See WIRING DIAGRAMS. Recheck system operation.
Measure resistance of Dark Blue/Light Green wire between RCC module harness connector C228 terminal No. 21 and temperature blend door actuator harness connector C289 terminal No. 7. See Fig. 3 and Fig. 10. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open or high resistance in Dark Blue/Light Green wire. See WIRING DIAGRAMS. Recheck system operation.

Measure resistance of Orange wire between RCC module harness connector C228 terminal No. 22 and temperature blend door actuator harness connector C289 terminal No. 8. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open or high resistance in Orange wire. See WIRING DIAGRAMS. Recheck system operation.
Remove temperature blend door actuator. Reconnect temperature blend door actuator connector. With temperature blend door actuator driveshaft disengaged from temperature blend door. Connect a fused jumper wire between RCC module harness connector C228 terminals No. 22 (Orange wire) and No. 11 (Red/White wire). See Fig. 3. Connect a second fused jumper between RCC module harness connector C228 terminals No. 21 (Dark Blue/Light Green wire) and No. 8 (Black/White wire). Note actuator movement.
Connect a fused jumper wire between RCC module harness connector C228 terminals No. 21 (Dark Blue/Light Green wire) and No. 11 (Red/White wire). Connect a second jumper wire between RCC module harness connector C228 terminals No. 22 (Orange wire) and No. 8 (Black/White wire). If temperature blend door actuator drives both clockwise and counterclockwise, repair blocked or binding temperature blend door as necessary. If temperature blend door actuator does not drive both clockwise and counterclockwise, replace temperature blend door actuator. Recheck system operation.
Drive temperature blend door actuator to full cool position (clockwise) by connecting jumper wires as in step 1. Measure resistance between RCC module harness connector C228 terminals No. 5 (Red/Light Green wire) and No. 20 (Red/White wire). If resistance is 5000-7000 ohms, go to step 13. If resistance is not 5000-7000 ohms, go to next step.
Disconnect temperature blend door actuator 8-pin harness connector C289. Measure resistance of Red/Light Green wire between RCC module harness connector C228 terminal No. 5 and temperature blend door actuator harness connector C289 terminal No. 6. See Fig. 3 and Fig. 10. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open or high resistance in Red/Light Green wire. See WIRING DIAGRAMS. Recheck system operation.
Measure resistance of Red/White wire between RCC module harness connector C228 terminal No. 20 and temperature blend door actuator harness connector C289 terminal No. 5. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open or high resistance in Red/White wire. See WIRING DIAGRAMS. Recheck system operation.
Measure resistance between ground and RCC module harness connector C228 terminal No. 5 (Red/Light Green wire). If resistance is more than 10 k/ohms go to next step. If resistance is 10 k/ohms or less, repair short to ground in Red/Light Green wire between RCC module and temperature blend door actuator. See WIRING DIAGRAMS. Recheck system operation.
Measure resistance between ground and RCC module harness connector C228 terminal No. 20 (Red/White wire). If resistance is more than 10 k/ohms, replace temperature blend door actuator. If resistance is 10 k/ohms or less, repair short to ground in Red/White wire between RCC module and temperature blend door actuator. See WIRING DIAGRAMS. Recheck system operation.
Drive temperature blend door actuator to full cool position (clockwise) by connecting jumper wires as in step 1. Measure resistance between RCC module harness connector C228 terminals No. 5 (Red/Light Green wire) and No. 9 (Yellow/Light Green wire). If resistance is 5-7 k/ohms, go to step 16. If resistance is not 5-7 k/ohms, go to next step.
Measure resistance of Yellow/Green wire between RCC module harness connector C228 terminal No. 9 and temperature blend door actuator harness connector C289 terminal No. 1. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open or high resistance in Yellow/Green wire.
Measure resistance between ground and RCC module harness connector C228 terminal No. 9 (Yellow/Light Green wire). If resistance is more than 10 k/ohms, replace temperature blend door actuator. If resistance is 10 k/ohms or less, repair short to ground in Yellow/Light Green wire between RCC module and temperature blend door actuator. See WIRING DIAGRAMS. Recheck system operation.
Operate temperature blend door actuator to full cool (clockwise) by connecting jumper wires as in step 1. Measure resistance between RCC module harness connector C228 terminals No. 5 (Red/Light Green wire) and No. 9 (Yellow/Light Green wire). If resistance is 3.5-6 k/ohms, go to next step. If resistance is not 3.5-6 k/ohms, replace temperature blend door actuator. Recheck system operation.
Measure resistance between ground and RCC module harness connector C228 terminal No. 5 (Red/Light Green wire). If resistance is more than 10 k/ohms, go to next step. If resistance is 10 k/ohms or less, repair short to ground in Red/Light Green wire between RCC module and temperature blend door actuator. See WIRING DIAGRAMS. Recheck system operation.
Measure resistance between ground and RCC module harness connector C228 terminal No. 20 (Red/White wire). If resistance is more than 10 k/ohms, go to next step. If resistance is 10 k/ohms or less, repair short to ground in Red/White wire between RCC module and temperature blend door actuator. See WIRING DIAGRAMS. Recheck system operation.
Measure resistance between ground and RCC module harness connector C228 terminal No. 9 (Yellow/Light Green wire). If resistance is more than 10 k/ohms, go to next step. If resistance is 10 k/ohms or less, repair short to ground in Yellow/Light Green wire between RCC module and temperature blend door actuator. See WIRING DIAGRAMS. Recheck system operation.
