Anyone else had this problem sometime they work for a lil bit but never when you need them too. I sounds like something making a clicking noise coming from the cruise control box when you flip the switch on?
quite possibly the wiper switch or turnsignal switch
mines been turning on the wiper when i hit the turn signal
common gm problem
i can ask me father what it is chances are i wont remember tho
For 1500 series trucks of the early 90's, you can still buy only the printed circuit board for a fraction of the price of a new motor. Maybe ours is the same. Generally when stuff starts f'ing up, its the motor.
