Did you drill by the passenger side to put mud guard? I did drill into the vacuum reservoir, and it went into default blowing cold air up the windshield check vacuum lines first.

SOURCE: Heater blows cold air when idle
Sounds like you may have a partially plugged heater core. You could flush this out separately, from flushing radiator & engine block. Diconnect heater hoses going to your heater core and clamp off, so not to loose coolant from engine. Now hook up separate hose to one side of heater core pipe and flush out with typical garden hose. Repeat procedure on both heater core inlets. Reconnect original heater hoses and test difference. You may have to add an additional litre of antifreeze. If this don't work i suggest changing heater core. Good luck.........Ron.

blend door actuators. If you have the AZC system (automatic zone control) used in the limited (the one with dual digital readouts) you can use the on board diagnostic to read the code. while running, press the a/c and recirc buttons at same time then turn drivers temp control one click clockwise. release a/c and recirc buttons. If you have codes that show up, write them down and google search for these codes. It will tell you exactly what is wrong.

How often has the coolant been changed? My only guess is that it hasn't and the hoses and the heater core are plugged up with goo and a flush is needed
