Glowing turn signals(usually only with the headlights or highbeams on- can
also be accompanied by a dead/darkened trip computer display) is the infamous
cracked solder joint. Top of the PCB, right over the speedo. Easily fixed
either by solder(semi-temporary repair, good for another 100K) or running a
new wire or two between solder points(permanent repair)- no new IC needed,
unless you're positive you fried something(and even then, it may only be the
voltage regulator, which is easily replaced). The instructions have been
linked to many times in posts to the 200q20v list- I think Chris Miller's page
probably also has a link to them.
