If it really bothers you, disconnect the heater lines in teh engine bay and splice them together for the summer. It's the constant coolant flow through the heater core that does it. I found it to be horrible in the summer months because I don't use AC. Now I don't use AC or heat lol

It can be reversed in minutes though
