I only get heat out of one vent on the dashboard.

2012 jeep liberty latitude. No matter how long I have my car warm up or drive it I can only get really hot air out of the passenger side left vent. I can get enough warmth or should I say lukewarm air to help melt the ice on the windshield if I wait long enough. When he is on its highest setting and only on the front vents the far left is blowing cold air the next one over going left to right blows lukewarm air then the next one over nice and hot than the last one on the passenger side maybe LUKE warm. The blend door works fine I replaced it myself last summer because it had broken teeth so that works fine. Has anybody else had this issue it could be something real easy or it could be a nightmare I’m not sure. Thank you all so much

Look around for videos on how to flush heater core. Took me 5 minutes and now it is too hot. I unhooked hoses on firewall and blew compressed air thru both pipes and followed by flushing with garden hose water. Hooked it back up. Simple and free fix.

With the engine cold swap the heater hoses that connect to the heater core on the fire wall. Right (Supply)hose to left (return) connection and left (return)hose to right (supply)connection. Drive it like that for a couple of weeks. This will push out the debris clogging up the heater core and reducing your heat. You should notice an immediate increase in heat. Get yourself a heater hose filter and install on the heater core supply hose when you put the hoses back the way they were. This will trap any debris from clogging the heater core back up. See my recent post on this!

Howdy All, A couple of weeks ago I noticed my Daughters 2009 KK AKA ”Quackers” was loosing heat at the heater vents. I fixed this once before by flushing and reverse flushing the heater core 2 years ago. This time I reversed the heater hoses and let her drive it like that for two weeks. Her...
