Having a problem with a 2010 Highline Golf. There seems to be no lukewarm air. It's cold right up until it reaches the max, then its to warm...? Anyone else have this problem? Thanks!

SOURCE: A/C blows warm air on left vent and cold air on right vent.

hello,good day,seems all the clarification request is all good,if all tips are done,but the problem is not corrected,send your car to a dealer,maybe one of the step motor of air flap is stuck or synchronized of all air flap is needed,they have the star diagnose to perform the job,or your recirculating pump need tobe check,ty

SOURCE: I just had a new

Had the same problem on a 2006 pilot LX. Hot from rear heater because it comes from a separate heater core. Front heat low because ball valve faulty that controls coolant flow to heater core. The lever on the valve would move freely but the connection to the shaft of the ball valve was stripped. Ball valve may be located on the firewall under the hood. Ball valve very poor design.

SOURCE: Left Vents blow warm/hot air when calling for cold air

Usually a sign of a faulty blend door under the dash.
The blend doors direct air thru the ac and heater core along with the upper and lower vents.
