Hey all

i hope you can help me.
after I change the clima module (HVAC system) i always get the message „ice possible“ and the starting temp is 88(31degrees) instead the 70(21 degrees) after 5 seconds it will change from 31 to 21 degrees…
somebody knows what should I do?
i checked some videos in youtube the the hvac must be calibrated in a special modus. But i cannot enter.

 

if it is dorman brand you have to follow there instructions.
