    I bought a new Prius v (lowercase v for the Prius v wagon) in 2012 & have hit 36,000 miles with no problems but now on chilly mornings when I want some heat, it only blows lukewarm air! Ex: Outside temp shows 63, I put it up to 75 and even after driving most of way to work, still blowing cool! Turned it up really high to 85 and slightly warmer. What's going on??!!
    Noticed no one in forum writes about this problem. Help. (n)

    that's a stumper. could be the thermostat, or a clog in the system, or the damper not moving all the way. sonds like a trip to the dealer, or a decent mechanic.

    Use auto mode. When its warmer outside it won't heat the air as much as when its cold out. You can't judge by the feel of the air coming out of the vents. Just set it at the temp you want it to be and don't worry about it unless you feel cold.
