2012 No Heat

Hello All, I have a 2012 Grand Cherokee Overland with an heating issue. while driving I notice that the heat doesn't work unless I drive above 3000 rpm. Blower works fine, but cold air comes out unless I'm above 3000 rpm, soon after I go below 3000 rpm then it goes from hot to cold. Please help!!!! 58k miles no warranty, I need advise before I go to the dealer.

Re: 2012 No Heat

if cooling system is full (no airlock), your heater core may be restricted.
