(Part number 7E0819045C9B9) Dashboard heater unit. Does anyone have or know anyone who has a spare one of the above please ? Mine has a damaged gear on the back of the hot/cold dial.

my dashboard heater started blowing luke warm yesterday, i took the trim off and pulled the unit out as far as it could. The plastic gear for the hot and cold dial has broken somehow. Does anyone know if i can buy this part separately and if so , whats the easiest way to replace it please ? @Pauly
