THIS ISSUE HAS BEEN CORRECTED....SEE LAST POST FOR CORRECTION.

I have an issue with the CJ2 displaying the temperature in Celcius instead of Farenheit.
This occured after I repaired a bad electrical issue with the car. Once I put the entire dash and all the moduels back together and started the car, I noticed the dispay in °C instead of °F.
Does anyone know how to change this back to °F??

Please don't say hit the Metric/English button on the DIC cause that does not affect the CJ2 display.
I have looked for the info on GM's tech site and can't seem to find this info anywhere.


Thanks!

Do you have the owners manual? Would think it would be in there.

I have every Manual known for these cars. But, I found it. It is listed in the wiring diagram for the CJ2.

There is a 1 wire connector, in the harness to the CJ2 that is broken out away from the main connector. It is about 12" behind the main CJ2 connector. If it is connected, it will read metric. If it is disconnected, it reads imperal.

All it does is either ground or un-ground that specific wire for switching the unit.
