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 1993 Gmc K35 problems

Based on the complaints from owners of the GMC K35 1993, several common problems have been reported:

Excessive Oil Consumption: Owners of 2007-2013 GMC and Chevy trucks, including the GMC K35 1993, have experienced issues with excessive oil consumption. This problem can lead to the need for frequent oil top-ups and potential engine damage if not addressed promptly.
Failed 4WD Transfer Case Encoder Motor Position Sensors or Selector Switches: Another common issue shared with 1999-2007 Chevy Silverados and GMC Sierras is the failure of the 4WD transfer case encoder motor position sensors or selector switches. This can result in difficulties engaging or disengaging the 4WD system, impacting the vehicle's drivability.
Failed HVAC Temperature or Delivery Mode Door Actuators: Owners have reported problems with the HVAC temperature or delivery mode door actuators failing. This issue can lead to inconsistent heating or cooling inside the vehicle, affecting comfort levels for the occupants.
Failed Fuel Level Sensors: Fuel level sensor failures have been noted in 2007-2013 models, including the GMC K35 1993. Malfunctioning fuel level sensors can result in inaccurate fuel level readings on the dashboard, leading to potential fuel gauge inaccuracies and uncertainty about remaining fuel levels.
Windshield Wiper Motor Component Failure: Models produced between 1990 and 1999, like the GMC K35 1993, may experience intermittent windshield wiper failure due to a defective wiper motor. This issue can manifest as the wipers not working, running at incorrect speeds, or failing to turn off, impacting visibility during adverse weather conditions.
Coolant Leaks or Oil Leaks From Intake Manifold Gaskets: Another reported problem involves coolant or oil leaks from the intake manifold gaskets. These leaks can lead to engine overheating, loss of coolant or oil, and potential engine damage if left unaddressed.
Alternator Failure: Older Sierras and Silverados, including the GMC K35 1993, may experience alternator failure. A failing alternator can cause the battery to drain, abnormal noises, and potential electrical system issues, impacting the vehicle's overall performance and reliability.
Internal Distributor Faults: Some drivers have reported internal faults in the distributor, leading to issues like engine roughness, stalling, or unusual noises. Addressing internal distributor faults is crucial to maintaining engine performance and preventing potential breakdowns.

These common problems highlight the importance of regular maintenance, timely repairs, and thorough inspections to ensure the optimal performance and longevity of the GMC K35 1993 and similar models.
