Just a GENTLE flush with a garden hose. Don't get aggressive or you will have leaks afterward.

Sounds like it could be a vacuum leak. Heater control valve, flap in the vent system?? May want to check that too!! Good luck!!

Thanks COS I was just responding to the heater core flush. You are probably right the vacuum hose is prolly off the little diverter motor.

And that little diverter valve is stupid cheap, at $20, and takes about 5 minutes to replace.

First check the vacuum hose, then, if that don't work, try the valve.
