My vent air blows slightly warm on both passenger and driver side. I’ve executed the recalibration exercise but that did not help. The A/C works well as do the heater and defroster |
 |
If the fresh air though the vents with the compressor off is slightly warm it would most likely be due to either worn door seals, software programming parameters or both. |

thanks. What would I do about those things? |
|
|
Honestly? Forget about it as long as the a/c and heat work properly. A minor problem with major expense and little chance of desired level of success. |

Thanks. I was thinking of trying to do the repair myself since I’m treating this car as kind of a project/learning thing. If I wanted to fix the blend doors, how would I do that? thanks again |

You would start by removing the temperature door actuator and manually close the door until you are sue it is completely at the end of travel you desire. Find a way to wedge the door shaft in place and then operate the vehicle to see if the problem is resolved. If it is then you will need to figure out if the foam on the door is compressed/worn enough that normal actuator travel will not seal it. Or if the actuator just is not designed to travel that far. If manually moving the door does not correct the issue then there is likely a problem with the internal door or the box itself. It would require disassembly or inspection with a borescope to determine the cause. |
