I have a cl500 mercedes 2001 and my heater blows hot on
the road but at idle it blows cooler air. Is this a head gasket problem or regulator or what air conditioning works great. Thank you
does not overheat runs great normal took on a long trip to montana from california noticed this in california when weather turned cool.
have the same problem?
