Compass/Temperature Mirror Internal Failure

Perform the compass/temp mirror self-check. Turn the ignition on. Press and hold the left lamp button for 20-25 seconds. The display will illuminate each of the VF segments: CAL, ZONE, N, NE, E, SE, S, SW, W, NW, the numerals 0 through 9, C° and F°. The compass/temp mirror will test the memory and the compass. Press the left lamp button or cycle the ignition to exit the self-check. If the compass/temp mirror displays an "F" after the self-check, replace the compass/temp mirror. If the compass/temp mirror does not displays an "F" after the self-check, the test is complete.
