Heater of my honda city 06 is not working properly in cold weather conditions. The green light which shows the temperature if on ( its usually remains on as very cold now a days and car did not get optimum temperature) while morning travelling from Wah cantt GT road to Islamabad. The heater blows normal air if not cold. But if green light is off it blows warm air.
My question is whether green light showing temperature usually gets off after travelling say 5 to 10 kms or it depends upon outside temperature ?
