Help me diagnose Climatronic

All,

So you may have read in a previous thread that I think my climate control is playing up. I followed the instructions on this site to access the diagnostics (i.e. press blue, fan speed down and econ).

I was expecting to be able to press blue and red to cycle through functions 00 to 44.

Instead, all I got was a number on the left, and a number on the right of the display.

The number on the left was 0, and then pressing the red button cycled the value on the right from 0 - 9. Upone reaching 9, the left value changed to 89 and the right value changed to 0.

Then it went back to 0-0 while occasionaly replacing the left number with a 1.

Anyone have a clue what's going on?

Edit : I relaised I pressed fan speed up instead of fan speed down. Any body know what this mode is?!
