Can you reset your S15’s malfunction warning light at home?

It may be tempting to reset the malfunction warning light on your S15, but it's important to resist the urge.

What Does the Drivetrain Do In Your 1990 GMC S15

The drivetrain is responsible for transferring power from your S15's engine to its wheels. It runs the full length of your GMC, from the axles to the transmission.

Care for your 1990 GMC S15 to maintain its performance power. You can help prevent repairs by checking and changing differential fluids, and lubricating bearings and gears according to GMC's recommendations.
