My C68 hvac is stuck on the hot setting there are no codes no flashing lights both the head unit and the programmer were sent to bate.com for repair because of fault code had them refitted two months ago worked ok yesterday could not turn the heating down all the other functions work ie the blower speed heated rear window the only other thing i noticed was when i hold in the two fan speed buttons for five seconds to enter diagnostic mode to two zeros only how once i release the buttons were as before they came on when the buttons were held down could the problem be a cracked gear wheel in the actuator ?
;help
