I just had the dash removed/reinstalled for a heater/ac issue. There wasn't a problem before that. Suggestions?

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 found the following description on the web, this covers a bunch of the questions I was going to ask...
I own a 2000 Silo and wondered the same thing and do see some GM vans with this problem.
When I bought mine I also bought the Haynes Repair manual (1997
thru 2001 all models GM) #38036 to learn how to fix this and a LOT of
other components in/on the van.
For $20 it's worth it.
To answer your question: If the wipers stop at the position
they're in when the switch is turned off (Fail to park), disconnect the
multi-function switch electrical connector. (This is located under the
dash next to the firewall and steering column)
If the wipers now park, replace the multi-function switch. If the
wipers still do NOT park, check the wiring from the wiper motor to the
switch for a short circuit. If the circuits are good, replace the wiper
motor.
Note: There are other adjustments needed for proper operation than just bolting and new motor on.
You can have a look at this manual at any automotive parts supply store.

The only other part that could be the problem with the winshield wipers not working in slow-mode or not park when you shut off the wiper switch is the winshield wiper motor, it has a park swith inside the motor to shut off the wipers and park them were they should be.

the little pump inside the washer fluid reservoir is bad, replace it
