Where is the wiper motor on a 94 Chevy conversion van g20?

The wiper motor on a 1994 Chevy G20 conversion van is located under the dashboard, behind the instrument panel on the driver's side. To access it, you'll likely need to remove parts of the dashboard trim. This is not a straightforward job and often requires some disassembly. A repair manual specific to your year and model would be very helpful in guiding you through the process.
