It sounds like your heater control valve is not shutting off all the way and allowing some heated anti-freeze to flow threw the heater core when it is supposed to be shut off. That happened to mine when it was new. It would heat the air when it was supposed to be vented air only coming in.

It also heated the air causing the air conditioning not to work efficiently.

They changed the heat control valve and problem was solved.

Good Luck, Ron
