How to Troubleshoot a 1993 Chevy Blazer
The 1993 Chevy Blazer was manufactured in the full size K1500 model with a 5.7-liter V8 engine and the smaller S-10 version with a 4.3-liter V6. Both vehicles have a box-style body with two rows of seats. The full-sized version provides more power for towing; the S-10 remains powerful enough for light duty applications. Troubleshooting for both vehicles requires basic mechanical observations to pinpoint issues.

Test the power if the engine is completely dead. Turn on the lights and watch the dash lights for flickering. Attach jumper cables to the car battery and a fresh battery to try to start the vehicle. If the battery continues to die, replace it with a new one. Also, test the alternator with a voltage meter and replace it if it fails to charge the battery.

Drive the vehicle on a flat surface to test the transmission's performance. Accelerate and decelerate to force shifting. If the Blazer stalls while shifting, the transmission must be serviced. Grinding and skipping gears are also indicative of transmission problems.

Take sharp turns after using the four-wheel drive. If the vehicle is difficult to turn, it may be stuck in four-wheel mode. The electric shift on the transfer case is a common cause of this issue with the 1993 model Blazer; have the vehicle serviced by a mechanic.
