No warm air coming from the vents
I've had my MG Urban for two weeks. So far, I've only used the air conditioning. Since it's colder in the mornings now, I wanted to turn on the heater. However, yesterday at first only cold air came out of the vents, then warm air came out of one vent while the others stayed off. This morning, only cold air was coming out of the vents, even though I set it to 27 degrees. Has anyone else had a similar problem and found a solution?
