where i can find the code?

 

Sit inside with the door closed. Cycle the key ON OFF ON OFF ON.....leaving it on.
Watch the mileage dispaly and see if it changes to show the code.

If it doesn't work on your Jeep, then you need to ue a code reader to get the code.

it show 4 codes,P1281,P.0141,P0171,P0131
Perfect, thanks. These are 92 sensors codes and one is them is for the heater circuit not working. If the heater doesn't work, then it may be causing the other codes to set so we will concentrate on the heater.

First, test fuse 16 in the underhood fuse box with a test light or meter with the engine running. We need to see 12 volts on both sides of this fuse.

If the fuse is good go directly to the sensor and check for the presence of 12 volts getting to the sensor.

Let m know how you make out......
