It's probably a faulty park switch.  Look at the 1987 Service Manual (http://www.73-87chevytrucks.com/techinfo/7387CKMans//Service/ST_330_87_1987_Chevrolet_Light_Duty_Truck_Service_Manual.pdf), page 1100 (8A-31), Figure 33, Procedure 5 - "WIPER SHUTS OFF BUT BLADES DON’T RETURN TO PARK POSITION" for the diagnostic procedure.
