1991 Chevrolet K35 problems
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 1991 Chevrolet K35 problems
The 1991 Chevrolet K35 is a popular choice for those seeking a reliable and robust pickup truck. However, like any vehicle, it is not without its common problems. This article will discuss two of the most frequently reported issues with the 1991 Chevrolet K35, based on complaints from owners of this car: the brake light dash issue and the truck shutting down while driving.
- Brake Light Dash Issue:
The brake light on the dash of the 1991 Chevrolet K35 has been a common problem for many owners. This issue can manifest in various ways, including the brake light being constantly on or blinking in a pattern. The root cause of this issue can be traced to several factors, such as a faulty brake light switch, the ABS system, or the wheel speed sensor.
The ABS system is a likely culprit for the brake light dash issue in the 1991 Chevrolet K35. The ABS system controls the rear wheel speed sensors, and if it fails, the brake light on the dash may come on or blink in a pattern. This issue can be particularly challenging to diagnose, as the ABS system is complex and requires specialized equipment to test.
If the brake light on the dash is blinking in a pattern, it may indicate a specific trouble code related to the ABS system. For instance, a pattern of three short blinks followed by one long blink corresponds to code 13, which indicates a blown module or a failed isolation dump solenoid.
To diagnose and fix this issue, it is recommended to consult a mechanic with experience in the ABS system. They can use specialized equipment to test the system and identify the root cause of the problem. In some cases, replacing the faulty component, such as the ABS module or the wheel speed sensor, may be necessary.
- Truck Shutting Down While Driving:
Another common problem reported by owners of the 1991 Chevrolet K35 is the truck shutting down while driving. This issue can be caused by several factors, including the ignition module, the computer, the fuel pump, or the sending unit.
The ignition module is a likely culprit for this issue, as it can cause the truck to shut down while driving, especially if it is failing or malfunctioning. The ignition module is responsible for controlling the spark plugs, and if it fails, the engine may stall or shut down completely.
Another possible cause of this issue is a faulty computer. The computer is responsible for controlling various aspects of the truck's engine and transmission, and if it fails, the truck may shut down while driving.
The fuel pump and sending unit can also cause the truck to shut down while driving. If the fuel pump is failing or the sending unit is malfunctioning, the truck may not receive enough fuel to keep running, causing it to shut down.
To diagnose and fix this issue, it is recommended to consult a mechanic with experience in the 1991 Chevrolet K35. They can use specialized equipment to test the ignition module, computer, fuel pump, and sending unit to identify the root cause of the problem. In some cases, replacing the faulty component may be necessary.
In conclusion, the 1991 Chevrolet K35 is a reliable and robust pickup truck, but like any vehicle, it is not without its common problems. The brake light dash issue and the truck shutting down while driving are two of the most frequently reported issues with this vehicle. To diagnose and fix these issues, it is recommended to consult a mechanic with experience in the 1991 Chevrolet K35. They can use specialized equipment to test the various systems and components of the truck to identify the root cause of the problem and recommend the appropriate repair.
