Hello everyone, I am new to the forum and am having heater problems with my 1999 Grand Cherokee ltd. I am getting heat out of the passenger side but cold air out of the drivers side. This just started this morning. I have started to do some research on the forum and it sounds like blend doors?? I have also read to hold the AC and Re-circ buttons down and turn the temp knob one click to get a fault code. I did this and two codes came up. It flashes between 54/56. Anyone have any suggestions as to what could be the problem?
Also what do I need to purchase to fix it and where can I purchase it?
Last question, do I need to pull out the dash board?
Thank you in advance
