1985 Gmc 1500 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).

Based on the sources provided, here are some common problems with the GMC 1500 1985 based on complaints from owners:
- Defective Speakers: Another common issue reported by owners of recent Chevy Silverados and GMC Sierras is speaker failure, especially in the door speakers. This problem often manifests as speakers failing one by one over several months. Some drivers have resorted to pulling the positive cable to reset the system, but this temporary fix may not always work effectively.
- Alternator Failure: In older Sierras and Silverados, alternator failure can occur, leading to battery issues and abnormal noises. This problem typically arises around 125,000 miles and may or may not trigger a warning light on the dashboard. Replacing the alternator, which costs around $300 to $400, is the recommended solution for this issue.
These are some of the common problems reported by owners of GMC trucks, highlighting issues related to oil consumption, speaker failures, and alternator malfunctions in different model years.
