Dash lights

[Furious1]

Hey,
I'm new to this forum, but I got a question that I didn't see asked b4. I just picked up an 87 n/a on ebay for $700, it's totally sweet. The guy said he'd stored it for two years and when he got it out, it wouldn't run or shift right (A/T) I just changed fluids and never had any problems runningwise with the car. However, the dash lights won't work at all, just the ones that light up the display face when the headlights are on, everything else works great (warning lights etc.) I've checked the obvious (bulbs, fuses) but nothing is working. electronically the only things that have been changed is the TEMS is disconnected due to aftermarket shocks and springs and someone hacked a CD player into it pretty badly. Oh, I don't know if this is in connection with the dash lights or no, but the heater/A/C panel's lights go out when the headlights are switched on and the orange warning light switch is on, but none of the lights bulbs are blown. Any ideas? I'm totally at a loss. . . thanks
