1994 Gmc C1500 pickup problems
The fourth generation of the C/K series is a range of trucks that was manufactured by General Motors. Marketed by the Chevrolet and GMC brands from the 1988 to the 2002 model years, this is the final generation of the C/K model line. In a branding change, GMC adopted the GMC Sierra nameplate for all its full-size pickup trucks, leaving the C/K nomenclature exclusive to Chevrolet.
Internally codenamed the GMT400 platform, GM did not give the model line a word moniker (e.g., "Rounded-Line series" for its predecessor). After its production, the model line would informally become known by the public as the "OBS" (Old Body Style), in reference to its GMT800 successor. In starting a different tradition, the model line overlapped production with both its predecessor and successor; the model line again shared body commonality with GM medium-duty commercial trucks.
Over nearly a 14-year production run, the fourth-generation C/K was assembled by GM in multiple facilities in the United States, Canada, and Mexico. After the 2000 model year, the fourth-generation C/K was discontinued and was replaced by the GMT800 platform (introduced for 1999); the C3500HD heavy-duty chassis cab model remained in production through 2002. In line with the GMC Sierra, Chevrolet subsequently adopted a singular Chevrolet Silverado nameplate for its full-size truck line (which remains in use).

Common 1994 Gmc C1500 pickup problems
The 1994 GMC C1500 pickup truck is known for several common issues that owners have reported over the years. Here are some of the most frequently mentioned problems:
- Wiper Motor Component Failure: The windshield wipers on models made between 1990 and 1999 may stop working intermittently due to a defective wiper motor control board. This problem can occur at any time, but it is most common at around 90,000 miles. If you experience trouble with your windshield wipers, check with a dealer to see if there is a recall on your vehicle. If you have a faulty wiper motor control board, your wipers may at times stop working, fail to turn on or keep running after you turn them off. You might also find your wipers only work on one speed setting. When the wipers are not working, you should hear the motor control box buzzing. As a temporary fix to the problem, lightly tap on the control box, and the blades should start working again. For a more permanent fix, replace the wiper motor control board.
- Coolant Leaks or Oil Leaks from Intake Manifold Gaskets: The intake manifold gaskets in 1988 and 1998 GMC C1500 pickup trucks often develop external engine oil or coolant leaks. These vehicles may also develop internal coolant leaks that cause coolant to mix with the engine oil, which can damage the engine. This problem most often occurs at around 175,000 miles. Fix this problem by replacing the intake manifold gasket, which will most likely cost somewhere between $300 and $450.
- Front Wheel Speed Sensor Failure: The front wheel speed sensors or anti-lock brake system (ABS) sensors may fail in the 1994 GMC C1500 pickup truck. This issue may cause the ABS warning light to turn on or the ABS to activate erratically. Many users report that the ABS activates on dry roads at slow speeds. This problem is most common at around 130,000 miles.
- 4L60E Transmission Shifting Problems: Some 1994 GMC C1500 pickup trucks with the 4L60E transmission may have trouble shifting out of low gear. This problem can occur intermittently or consistently and may be caused by a faulty switch or computer issue. If you experience this problem, it is recommended to check the computer for error codes and replace any faulty components.
