"90" Instrument/LCD problem
I'm hoping someone one can help me on this... After starting/boosting my car after winter, the first time driving it the LCD starting throwing random numbers. I checked for codes from the CCM and found no codes other than the C12. I changed out my battery and checked the voltage off my alternator (steady at 14.89V) at different engine speeds.
I followed the instructions in the FSM, checked the grounds, all ok. The FSM said to replace the cluster, I did and the replacement cluster is doing the same thing. The only other thing I can think of is a faulty CCM, as sometimes the C68 heater controls go from the "OFF" selected position to auto, no matter how many times I select the "OFF".
I'm pretty much out of ideas, can anyone help? How much is a CCM?
