There are only two values. Numerical value 1 is displayed in the right side when the left says P1. Similarly for numerical value 2.

You probably want 16 for P2. For P1, it seems that you'd want either 8 or 40 (8+32). What I posted there is all the climate-control diagnostic manual seems to say about these values. As I have a '96, I haven't investigated.

You already know this, but for others who may find this thread, you really should write down these numbers before you do anything like change them or change the pushbutton control module.
