Guys and gals, fellow renegades! If you have a faulty ambient air temperature reading (and as a result, a check engine light), you will find that requesting a repair will likely by upwards of $500 at the dealership. OR you can buy the part you need (which is called a thermistor) for about $5.00...
I have a 2016 Renegade with a Temperature reading of '---' and no air con because of this.
I have tried the two simple fixes suggested on the internet but neither worked;
1. sprayed a circuit contact cleaner in the connector and mount ( by the door hinge ).
2. Cut out the air...
