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 Gmc R1500 problems

The 1991 GMC R1500 Suburban is a well-built and reliable vehicle, but like any other vehicle, it can have its fair share of issues. In this article, we will discuss some of the most common problems with the 1991 GMC R1500 Suburban based on complaints from owners of this car.

1. Distributor Problems

The distributor is a crucial part of the ignition system in the 1991 GMC R1500 Suburban, as it is responsible for sending the spark to the spark plugs. The distributor is located right under the hood, and it contains a wheel that sends a signal to the ignition module, which then sends the signal to the coil. The coil then sends the spark to the top of the distributor cap, which then goes through the rotor and out to each individual spark plug wire.

One common problem with the distributor is that the wheel or the ignition module can crack, which can lead to no spark or intermittent spark. This can cause the engine to not start or run poorly. It is essential to keep up with maintenance and replace the cap, rotor, plugs, and wires regularly.

2. Fuel Pump Problems

The fuel pump is responsible for delivering fuel from the gas tank to the engine. If the fuel pump fails, the engine will not receive enough fuel, and the vehicle will not start. In some cases, the fuel pump may make a loud noise or whine, indicating that it is failing.

One common problem with the fuel pump is that it can become clogged with debris or rust, which can cause it to fail. Replacing the fuel filter can help prevent this issue. If the fuel pump does fail, it will need to be replaced.

3. ABS Problems

The Anti-lock Braking System (ABS) is a safety feature that prevents the wheels from locking up during hard braking. If the ABS warning light is on, it indicates that there is a problem with the ABS system.

One common problem with the ABS system is that the ABS module can fail, which will cause the ABS light to come on. The ABS module is responsible for controlling the ABS system, and if it fails, the ABS system will not function properly.

4. Door Handle Problems

The door handles on the 1991 GMC R1500 Suburban can become worn or broken, which can make it difficult to open the doors. The exterior door handles are especially prone to wear and tear, as they are exposed to the elements.

Replacing the door handles can help prevent this issue. It is essential to use high-quality door handles that are designed to fit the 1991 GMC R1500 Suburban.

5. Heater Control Problems

The heater controls on the 1991 GMC R1500 Suburban are responsible for controlling the temperature inside the vehicle. If the heater controls are not working properly, it can make it difficult to maintain a comfortable temperature inside the vehicle.

One common problem with the heater controls is that the blend door actuator can fail, which will prevent the heater controls from working properly. Replacing the blend door actuator can help prevent this issue.

In conclusion, the 1991 GMC R1500 Suburban is a reliable and well-built vehicle, but like any other vehicle, it can have its fair share of issues. By keeping up with maintenance and addressing these common problems promptly, you can ensure that your 1991 GMC R1500 Suburban remains a reliable and enjoyable vehicle to drive.
