The fact that you have to unplug the wiper motor for the wipers to go off and your turn signals do not work says that the problem is with the multi function switch in the steering column.

That is your turn signal switch in the steering column.

I got into the steering column and changed the multi-function switch with the year that was interchangable 91 thunderbird this is the second time i have done that, checked all fuses and still the same. Is there a relay someware that could be faulty and if so ware is it at, and how can i change it, or check it and what dose it look like ware is it at
Your model only shows an internal governor between the switch and the wiper motor,that is the only other thing that will keep the wiper running now.
If the turn signals light up and not flash then it will be the flasher relay on the right side of the steering column.

the turn signals do not light up on the dash or anyware
I think you have more than one problem, a power supply (fuse) problem to the turn signals and a problem with the governor on the wiper motor.
