Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome. My name is ***** ***** you for visiting the site, I am reviewing your question and will reply shortly, thanks.
Which sensor did you disconnect the sensor and blue red wiring to ground?
I see, thanks. That could be what the problem is that set the code. However, they did have some issues on some with manual controls for the door actuators.
Yes, they had issues and there were some that had recalls for the door actuators. It was a software issue.
Safety Recall J12Reprogram HVAC Control Head Module
As for the trouble code P0073, the test would have to be done to determine the exact problem. The wire goes to the PCM.
I don't see how 'disconnecting' it will fix it.
So the HVAC controls are not working?
There is not a specified resistance spec for them and yes, one of the wires is the AAT signal and the other is grounded through the PCM.
Do you see the offer for premium services on that end?
Or maybe the mode/temp 'doors' that are not responding to the HVAC commands?
Yes, I already stated that. There are a lot of 'maybe's' and I am not sure what you are trying to get working on it.
I see, thanks.
Let me just say that any money that you paid, or if you have a subscription, that money stays in your account until the answers are rated, (positive) regardless of how fast or how long it may take to get finished. You can FOLLOW UP AT ANYTIME, even after rating.
If the wiring is good, chances are that the sensor is just bad. It is also possible that the mode door actuator is what is wrong with the heating system. However,
"The HVAC Control Head Module on about 36,700 of the vehicles may have an inoperative mode door." The HVAC Control Head Module must be reprogrammed, as per factory service bulletin/recall.
Sure that goes to the TIPM, (totally integrated power module) under the hood.
Please don’t forget to rate the answer in a positive way, . EVEN IF YOU HAVE A SUBSCRIPTION ****THAT IS THE ONLY WAY I GET PAID **** Thanks
