Hello all, I have an 89 Grand Prix SE 5 speed with a 2.8L(not the original engine). I am having problems with my instrument cluster, and hoping someone here can lead me on the right path.
Most of the time the cluster will come on with fuel take and full, odometer reading is ERROR, 0mph while driving, No tach readout and temp, oil, volts will occasionally readout but i don't believe they are accurate.
I assumed that the cluster was just bad and replaced it with a tested and working one from a junkyard. The only difference is that it is for and automatic with manual gear selection at bottom, should not cause any problems other than looks bad. After replacing the same problem still exists.
I know that the cluster worked after the engine was swapped, and the main computer was replaced at one point.
Any suggestions? or Q's? This is turning out to be a troublesome problem. Thanks for all the help in advance.
