The heat in my 2004 just stopped working about a month ago. It is not blowing any air. The self diagnostic reflected needing a new blower motor. So I replaced the blower motor and nothing happened. I have checked the fuses, and even purchased and installed a new heater motor resistor as well. After installing the resistor, the blower motor came on and worked for about 15 minutes and then just stopped. Now I am back to square one... and freezing. Any ideas?

what was the dtc diagnostic code? was it problem with the blower motor circuit (12 blinks)? this type of problem is very hard to figure out because of all the wiring involved. it may be a bad ground or loose connection.
