What is causing my heat to come on for short bursts and quickly turn cold?
Air conditioning is working fine. Heat began taking awhile to come on (about 15 minutes of driving until air would turn heated). Now not only does it take a long time to come on, but it will intermittently turn cold. I must shut the air off completely and try it again 10 minutes later, for which I'll get another 30 seconds of heat.
Insufficient coolant , trapped air in the cooling system might not have enough coolant to full fill the heater core.
