A/C Code?

I have a code 4-1 612-14A. I believe that is something in the a/c system switches but not sure. Can you I.D. which switch it is causing the problem.

    Give me a second to analyze all of the details you provided. This may take awhile.

    Year make and model of truck would be helpful. VIN as well.

    Those Paystar thermistor switches are a problem child. The dealer sells an update kit with both switches and new wire harnesses. (which, will also fail in short order.) Just follow the instructions. Good luck.

    Fantastic. We will get them and install with the kit.
