1991 Chevrolet K1500 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 1991 Chevrolet K1500 problems
The Chevrolet K1500 1991, part of the fourth generation of the C/K series, is known for its reliability and robustness. However, like any vehicle, it has certain common problems that owners have reported over the years. Here are some of the most frequently mentioned issues, along with their causes and possible solutions:
- Wiper Motor Control Board Failure: The wiper motor control board is responsible for controlling the speed and operation of the windshield wipers. If it fails, the wipers may not work at all, or they may work intermittently or at the wrong speed. This can be caused by wear and tear, exposure to moisture, or a manufacturing defect. To fix this issue, you may need to replace the wiper motor control board or the entire wiper motor.
- Engine Oil Leaks: Engine oil leaks are a common problem in older vehicles, and the K1500 is no exception. The most common sources of oil leaks are the oil pan gasket, the front and rear main seals, and the oil filter adapter. These leaks can be caused by wear and tear, age, or lack of maintenance. To fix an oil leak, you may need to replace the faulty gasket or seal, or the entire component if necessary.
- Tail Light Board Failure: The tail light assemblies in the K1500 contain electrical circuit boards that the bulbs attach to. If these circuit boards fail, the tail lights may not work at all, or they may work intermittently. This can be caused by wear and tear, exposure to moisture, or a manufacturing defect. To fix this issue, you may need to replace the tail light board or the entire tail light assembly.
- Grounding Issues: The K1500's electrical system relies on a network of ground straps and wires to ensure a stable and reliable electrical connection. If these ground straps become loose, corroded, or damaged, it can cause a variety of electrical issues, such as intermittent power, flickering gauges, or even engine stalling. To fix this issue, you may need to clean, tighten, or replace the faulty ground straps or wires.
- Distributor Problems: The distributor is responsible for sending the spark to the spark plugs in the K1500's engine. If the distributor fails or malfunctions, it can cause a variety of issues, such as engine misfiring, poor performance, or even engine stalling. This can be caused by wear and tear, age, or lack of maintenance. To fix this issue, you may need to replace the distributor cap, rotor, or the entire distributor.
It's important to note that these are just some of the most common problems reported by K1500 owners, and that not all vehicles will experience these issues. Proper maintenance, regular inspections, and timely repairs can help prevent or mitigate many of these problems, and ensure a long and reliable service life for your K1500.
