Sorry , no adjustment .
Wiper/Washer System Components
The Wiper / Washer System consists of the following components:
• Windshield wiper / washer switch
• Windshield wiper system module / motor
• Windshield washer fluid pump
• Windshield washer fluid level switch
• WPR 25A fuse
Wiper / Washer System Operation
The windshield wiper motor module is part of the windshield wiper motor cover and controls the wiper motor operation. The windshield wiper motor is a 2 speed motor. Windshield wiper DELAY operation is a low speed wiper motor function with a variable delay interval between the wipe cycles. The DELAY interval is controlled through a series of resistors within the wiper / washer switch.
Park Position Operation
When the windshield wiper / washer switch is turned to the OFF position while the wiper motor is somewhere in mid-cycle, the wiper motor module will continue to operate the wiper motor until the wipers reach the park position. If the ignition is turned off while the wipers are in mid-cycle, the wipers will stop immediately where they are. The wipers will park the next time the ignition is cycled to the ON position.

Gremlins ! No ! You want to know how this is possible ? The ignition switch is a low voltage input to the BCM - body control module ! Going by which position you have the key in ACCY , ON , run or start . The BCM system will control relays to turn on power to different parts of the vehicle ! The place to start would be to hook up a professional type scan tool that can communicate with the BCM . Could have U codes stored in one or more of the modules on the vehicle ! Do you know what a power mode master PPM is , BCM !
BCM Functions
The body control module (BCM) performs multiple body control functions. The BCM can control devices directly connected to its outputs based on input information. The BCM evaluates this information and controls certain body control systems by commanding outputs on or off. The BCM control inputs can be:
• Sensors and switches that are directly connected to the BCM
• Class 2 serial data received from other vehicle systems connected to the class 2 serial data link.
The BCM is also capable of controlling other vehicle systems that are not directly wired to the BCM. The BCM does this by sending specific messages on the class 2 serial data link. The system capable of performing the required function will respond to the BCM message.

Your best bet would be to take your vehicle to a Buick dealer !
Power Mode Master
This vehicles BCM fuctions as the Power Mode Master (PMM). Refer to Power Mode Description and Operation for a complete description of power mode functions.

What repairs were performed 3 years ago to solve the problem? Reoccuring problems can be a pain no doubt. Check with the repair shop that did the repair 3 years back if they're can repair or advise you on your options to resolve this issue.

Probably not the tranny. Check the drive shaft to see if a bit of trash has wrapped itself around the shaft causing it to slap the bottom of the vehicle when moving.

Have it hooked up to a diagnostic scan tool ,check engine sensor data parameters . Fuel pressure test it as well ! Check for vacuum leaks .When it stalls have you try pushing on the gas pedal a little an then trying to start it then ? Not to the floor because this cuts off fuel injectors .

One end should have a nut on the fuel line. The other usually has a spring lock inside the fuel line and will require a special disconnect tool to release it
