Just bought an 03 Grand Cherokee Limited with an inline 6. It has the premium climate control system with the infrared built in eye. The A/C works great however the heat does not. The climate control ***** work fine and the LED temp display increases and decreases when turning the **** but it continues blowing cold air regardless of the settings. Any suggestions?

sounds like you have an issue with blend doors. do a search on blend doors and you will find many symptoms of heater problems, and solutions as well

Thank you for the 411. I printed out some AZC information and will run the codes to see what pops up.
