WINDSHEILD WIPER ISSUES...MORE HELP

The previous owner of my car was having wiper issues before i picked up the car. I replaced the wiper motor and the wipers now move but when the interior switch is placed in the "o" position(off) the wipers keep going. I assumed the interior switch may be broken so i got a used switch from the same friend who gave me the wiper motor and still no change in the problem. The switch was out of a 91 5.0 lx and the wiper motor is a 2 plug out of a 89 or 90 notch back. Does anyone know whats wrong with this thing????...Im starting to loose hair from this stang..... lmao

I would apprecciate any help guys.....


Thanks

Adam
