My son came down and figured it out for me. Not sure what all he did but he had to make a few modifications by splicing the wires together after cutting the wires just under the dimmer switch...then a few adjustments were needed to get it to all work right.

I hate to say it but GM "W" bodies of that time period ( Regal, Cutlass Supreme, Lumina, and Grand Prix) are notorious for turn signal problems. I'm a machanic and also have owned 3 W body vehicles. The pivot bushing in the switch wears prematurely and in turn causes the copper contacts to barely touch each other. If the contacts are dirty, there is resistance. Where there is resistance, there is heat, hence the smoke. It's just a poor design. What I do instead of replacing the switch requires some time and some surgical skill but it always works for me. At the pivot end of the switch, I remove the screw and remove the metal tube insert. I wrap the metal with electrical tape to take up the slack from the wear then grease the heck out of it. At the contact end I attach a piece of sheet metal to the bottom of the movable part of the switch so it sits underneath the non-moveable part making it so the moveable part can't lift up and lose contact. That's just a vague description but if you want a detailed one let me know and I'll write one. I did it to my '89 Regal 4 yrs. ago and to my wife's Grand Prix 1 yr. ago and they both still work great. Just a design flaw in the switch. Sometimes you have to pick up wher the car companies left off! beest921

I believe your car has 2 flashers, one hazard, one turn signal. Check the turn signal flasher to see if it's bad. Located driver side, upper steering column under dash. To make sure u check the correct flasher, try using the hazards after removal of flasher, so u know u have removed the correct one. Let me know how u do.
