Question about 1998 Pontiac Firebird
When I turn of my windshield wipers they stay in the up position.
There is a small circuit board that controls the parking of the windshield wipers. I believe it is on the firewall on the drivers side. Temporarily you can remove the fuse when the wipers are down and put the fuse back when it rains.

yes google this problem and you will find that under the wiper motor is a plate with a metal tab that should be bent @90 degees. over time it bends down and will not contact the oter metal plate on motor.. you need to remove cap holding wiper arms on then remove wiper arm, then remove plastic cowling, the remove plastic cover over motor, then u will see tab bend it back up and u will be fixed. mark wiper arm position on shaft so you assemble in the same position

The body control module (BCM) controls the wiper motor based on input from the windshield wiper washer switch. The BCM monitors the wiper washer switch through three separate signal circuits and a ground circuit. The windshield wiper switch high signal circuit is used to determine high speed wiper operation, the windshield wiper switch low signal is used to determine low speed, intermittent, and mist operation through the use of a resistor ladder, and windshield washer switch signal circuit is used to determine washer operation. The windshield wiper motor park operation is controlled by the BCM. The BCM recieves an input from the park switch to determine wiper blade position. When the wiper blades are at the bottom of the windshield glass in park position the wiper park switch will open and the circuit will be pulled up to B+ by the BCM. The park signal will be pulled to ground by the wiper motor park switch while the wiper blades are not in the park position.
The BCM controls the windshield wiper motor through two output controls, controlling two relays which determine the desired wiper speed, high or low
Diagnostic Trouble Codes (DTCs)
The body control module (BCM) monitors the voltage on the windshield wiper switch signal 2 circuit for diagnostic purposes. If the circuit is shorted to voltage while the driver is commanded OFF, the BCM will store DTC B3715. If the circuit is shorted to ground while the driver is commanded ON, the BCM will store DTC B3715. Refer to DTC B3715.
It would be best to have a factory scan tool to diagnose this problem . it would make it easier anyway .
