The third generation of the C/K series is a range of trucks that was manufactured by General Motors from the 1973 to 1991 model years. Serving as the replacement for the "Action Line" C/K trucks, GM designated the generation under "Rounded Line" moniker. Again offered as a two-door pickup truck and chassis cab, the Rounded Line trucks marked the introduction of a four-door cab configuration.

Marketed under the Chevrolet and GMC brands, the Rounded Line C/K chassis also served as the basis of GM full-size SUVs, including the Chevrolet/GMC Suburban wagon and the off-road oriented Chevrolet K5 Blazer/GMC Jimmy. The generation also shared body commonality with GM medium-duty commercial trucks.

In early 1987, GM introduced the 1988 fourth-generation C/K to replace the Rounded Line generation, with the company beginning a multi-year transition between the two generations. To eliminate model overlap, the Rounded Line C/K was renamed the R/V series, which remained as a basis for full-size SUVs and heavier-duty pickup trucks. After an 18-year production run (exceeded only in longevity by the Dodge D/W-series/Ram pickup and the Jeep Gladiator/Pickup), the Rounded Line generation was retired after the 1991 model year.

From 1972 to 1991, General Motors produced the Rounded Line C/K (later R/V) series in multiple facilities across the United States and Canada. In South America, the model line was produced in Argentina and Brazil, ending in 1997.

Common 1994 Chevrolet K30 problems

The Chevrolet K30 1994 is known to have several common problems, which are discussed in detail below:

Blower Motor Resistor Failure: The blower motor resistor is responsible for controlling the fan speed of the heating, ventilation, and air conditioning (HVAC) system. In the 1994 K30, the blower motor resistor is a common failure point. When it fails, the fan may not operate at all or may only operate at one speed. To fix this issue, the resistor must be replaced.
Steering Wheel Position Sensor Failure: The steering wheel position sensor helps the vehicle determine the position of the steering wheel and is used for stability control. In the 1994 K30, this sensor can fail, causing a service stability message to be displayed. This issue may occur intermittently or every time the vehicle is started or the wheel is turned. Replacing the sensor should fix this issue.
Coolant Leaks or Oil Leaks from Intake Manifold Gaskets: The intake manifold gaskets in the 1994 K30 are known to leak coolant or oil. This can cause the engine to run hot or result in reduced performance. In some cases, the leaks can be repaired by resealing the gaskets, but in other cases, the gaskets may need to be replaced.
Alternator Failure: The alternator in the 1994 K30 can fail, causing the battery to die and potentially resulting in an abnormal noise. This issue may or may not cause a dash warning light to come on. If the alternator fails, it will need to be replaced.
Internal Distributor Faults: Some 1994 K30 owners have reported internal faults in the distributor, which can cause a squealing noise and rough engine running or stalling. The check engine light may or may not come on. This issue can be corrected by overhauling or replacing the internal distributor.

It is important to note that these issues may not occur in all 1994 K30 vehicles and may depend on factors such as maintenance history and driving conditions.
