'91 200tq20v instrument cluster issues (how odd,lol)

Ok the boss' '91 200tq20v cluster has been acting up for a while now,  
and since we have the head off and are slow in the shop he asked me to  
take a look. Everythings fine until you turn on the lights. Parking  
and/or headlights on cause the symptoms. The turn signals both glow  
dimly constantly, if you turn on a turn signal (either direction) the  
indicator on the dash flashes between proper brightness and the dim,  
and the other turn signal flashes also in the exact oposite pattern.  
Also the clock will slowly dim out and back in in sync with the turn  
signal flashing. Activating the high beam will only very very dimly  
light the corresponding indicator, and here again the clock will  
slowly fade away as you hold the high beams on. Move the headlight  
stalk to the off position and everything goes back to working as new,  
even the high beam indicator.

I'm the 2nd person to dive in to it, about 3 years after the initial  
attempt. I followed the suggestions on Scott's website about cold  
solder joints, and even though I didn't find any I went through and  
re-flowed every joint I could touch. No change.

Ideas, tips, clusters for sale? ;-)
