Hey all, happy winter. My wife has a 2008 kk and we ate having problems with the heater. It blows cold on the driver side however it is warm on the passenger side. I have checked the coolant level and it was slightly low so I added some more and that didn't do anything. I removed and sprayed the blend door actuator and that seemed to help a little but now it is cold again. Does anyone have any ideas before I attempt to flush the heater core and see if that does anything. If you think I need to flush the heater core can you please send me a link to instructions how get it out. Thanks!
