We are the original owners of a 1991, L98 coupe in Turquoise Metallic with every available option that could had with the automatic transmission. The car now has 63K original miles and still appears as new.

Today we took it on a run and notiiced a strange electrical problem.

The radio does not come on, nor does the antenna go up. The clock shows 1:00 and cannot be changed. Additionally, the outside temp continues to display 80 degrees, even though it was much warmer. Additionally, the fuel gauge displays all bars, even though the tank is not full. Also, the courtesy door lights don't come on when the door is opened, but do come on when the hatch is lifted. All analog gauges appear correct.

Also, initially the service ABS light came on but now is out, though it is not going through its initial self test.

When I start the car (starts and runs fine with A/C and all), all the panel functions in the initial display show up as normal.

I pulled all fuses and all are good.

The ABS was doing this previously, and came back and went again, an I attribute this to possible corrosion in a plug (behind the drivers seat?). I'm assuming that these other problems (whether related to the ABS or not) are interrelated and most probably due to corrosion in a plug or relay terminal.

Does anyone have any idea where to look???
