20 Most Recent 1994 Chevrolet S-10 Questions & Answers

It sounds like there may be a problem with the transfer case of your 1994 S10 4x4. The transfer case is responsible for transferring power from the transmission to the front and rear axles, and it allows you to switch between 2-wheel drive (2H) and 4-wheel drive (4H and 4L). If the transfer case is not functioning properly, it can cause the truck to behave as if it is stuck in 4-wheel drive, even when the lever is moved to a different position. There are several potential causes for this issue, including a faulty transfer case control module, a damaged transfer case shift motor, or a problem with the transfer case shift linkage. In order to determine the root cause of the problem, it will be necessary to have the truck inspected by a mechanic. They will be able to diagnose the issue and recommend the necessary repairs.
