95 Sunfire PRNDL indicator not working

I have a 1995 Sunfire SE with AT. The PRNDL indicator LED's in the instrument cluster is not working.

I have checked the transmission switch and it is OK. A Tech tool shows that the PCM is getting the signal to determine what gear it is in. I have replaced the PCM and still no indicator lights. I thought that maybe the PCM was getting the proper signal, but not sending it up the data line to the cluster.

I have also replaced the instrument cluster.

EVERYTHING checks out OK. Transmission switch, PCM, cluster....What am I missing?

Thanks,

HCII

I'm assuming you have a floor shifter, correct? If so, are you refering to the little indicators next to the shift handle? That or you have something I've never seen before.:grinno:

Yes, it has the floor shifter. But...

There is an indicator built in to the instrument cluster at the top center. There are the letters P R N D L there, and above these letters is a set of LED's that light up above the correct indicator. The signal for this comes from the computer.

That's weird, I never look at my PRNDL indicator and somehow I still know when my car is in drive and when it's in park. Maybe I should sue GM as well. them.
