Heater blowing hot + cold / losing coolant
I have a 2005 Mini Cooper with air-con.
The fan seems to blow intermittent hot and cold. Randomly, the heater will blow cold air even though temp set to hot.
The car has been drinking coolant for the last month or so. Prob at a guess, maximum down to minimum level every 2 weeks. Thought this might be an airlock but so far it's still drinking the stuff.
Any ideas on what is wrong with the car?
