The Chevrolet C/K is a series of trucks that was manufactured by General Motors from the 1960 to 2002 model years. Marketed by both the Chevrolet and GMC divisions, the C/K series encompassed a wide range of vehicles. While most commonly associated with pickup trucks, the model line also included chassis-cab trucks and medium-duty trucks and served as the basis for GM full-size SUVs. Through its entire production, the model line competed directly against the Ford F-Series and the Dodge D series (later the Dodge Ram pickup).

Used for both the model branding and the internal model code, "C" denoted two-wheel drive, while "K" denoted four-wheel drive. Four generations of the C/K series were produced, including the GM monikered second-generation "Action Line" and third-generation "Rounded Line" vehicles (colloquially aka Square-Body trucks). For the fourth-generation (colloquially also known as OBS trucks), Chevrolet kept using the C/K designation while GMC revised its branding, changing to a singular GMC Sierra nameplate (C/K remained as an internal model code).

For South America, the model line was manufactured by General Motors de Argentina from 1960 to 1978, Sevel Argentina from 1986 to 1991, and General Motors Brazil, who produced versions of the model line for Brazil, Argentina, and Chile from 1964 to 2001.

As GM entered the 1990s, the company revised its truck ranges, replacing the medium-duty C/K trucks with the Chevrolet Kodiak/GMC TopKick for 1990. For 1999, GM replaced the fourth-generation C/K pickup trucks with an all-new model line; in line with GMC, Chevrolet dropped the C/K nameplate (in favor of a singular Chevrolet Silverado nameplate). Initially marketed with its successor, the final C/K pickup trucks were produced for the 2000 model year. From 2001 to 2002, the final vehicles of the C/K model line were medium-duty chassis cab trucks.

Common 1994 Gmc C25 problems

The GMC C25 1994 has been known to have several common problems based on complaints from owners. Here are some of the most frequent issues and their details:

Distributor: The distributor is a crucial component in the ignition system, responsible for directing the spark to the spark plugs at the right time. In the GMC C25 1994, the distributor is prone to cracking, which can lead to no spark or intermittent spark, affecting the engine's performance. Regular maintenance, such as replacing the cap and rotor or plugs and wires, can help prevent this issue. Additionally, the ignition module can also go bad, causing similar problems.
Fuel Pump: The fuel pump is responsible for delivering fuel from the gas tank to the engine. In the GMC C25 1994, the fuel pump can fail, leading to fuel starvation and difficulty starting the engine. A faulty fuel pump can also cause the engine to run poorly or stall while driving.
ABS Problems: The Anti-lock Braking System (ABS) in the GMC C25 1994 can develop issues, such as the ABS light illuminating on the dashboard. This problem can be caused by various factors, including faulty wheel speed sensors, a malfunctioning ABS control module, or damaged wiring.
Door Handles: The door handles in the GMC C25 1994 can wear out or break, making it difficult to open the doors. This issue can be particularly problematic in cold weather, where the door handles can become stiff and hard to operate.
Heater Controls: The heater controls in the GMC C25 1994 can develop problems, such as the heater not blowing warm air or the temperature control not functioning correctly. This issue can be caused by a faulty heater core, a malfunctioning blend door actuator, or a damaged temperature control cable.
Tail Gate: The tail gate in the GMC C25 1994 can develop issues, such as not opening or closing properly. This problem can be caused by various factors, including worn-out hinges, a faulty latch mechanism, or damaged wiring.

In summary, the GMC C25 1994 has several common problems, including issues with the distributor, fuel pump, ABS, door handles, heater controls, and tail gate. Regular maintenance and timely repairs can help prevent these issues and ensure the vehicle's longevity and reliability.
