Turn Signal and High Beam Indicators not working

[Dave Henneman]

Just wanted to get any ideas about what may be going wrong with my turn signal and high beam indicators. All of the exterior lights work, but I get no indication of the turn signals or high beams being on from the cluster. I took the cluster out and all of the three lower bulbs that light for these functions seem to be good. There is no audible alert either. I checked all of the fuses I could find, to no avail. I purchased the Allante this way and really don't know how to proceed. I plan on getting a FSM in the near future, but don't have one yet. Any help would be deeply appreciated.

Regards from snowy Colorado,

That problem is caused by a defective rear circuit board inside the cluster. $225 plus return shipping to replace the rear board.

I can narrow it down a little. This problem only happens on 1987 through 1989 models.
