Can anyone give me help on locating the compass module. I have an 04 eddie bauer with the 5.4 engine. when I try to calibrate the compass on the dash it says check compass module. all I see next to my mileage is two lines where my direction heading used to be. I dont think my compass is on the mirror, but I could be wrong. This all started after a supposedly qualified shop changed my blend door actuators (which they clocked wrong and I still got zero heat). Any help is appreciated.
