What Problems Does the 1981 Chevrolet Silverado 1500 Blazer Have?
The 1981 Chevrolet Silverado 1500 Blazer, like many vehicles of its era, is susceptible to age-related issues. One of the most pervasive problems is rust. It tends to afflict the frame, especially near the rear axle and spring perches, as well as rocker panels, floor pans, and the rear quarter panels. Significant rust can compromise the vehicle's structural integrity and lead to costly repairs or make a restoration unfeasible.
Engine and drivetrain issues are also common. Carburetors can become finicky, requiring frequent adjustments or rebuilding, and older V8s may develop oil leaks, coolant leaks from worn hoses and radiators, or consume excessive oil. The 700R4 automatic transmission, introduced in this era, can be prone to wear, especially if the vehicle has been used for heavy towing or with aggressive driving.
Electrical system problems are another frequent complaint. Components like the alternator, starter, and various sensors can fail due to age. Wiring harnesses can become brittle and develop shorts, leading to intermittent issues with lights, gauges, and other electrical accessories.
Suspension and steering components, such as ball joints, tie rod ends, and bushings, will likely be worn on a 1981 model, leading to sloppy handling and potential safety concerns. Power steering pumps can also leak or fail.
While specific model year recalls for the 1981 Blazer are not as prominently documented as some later models, general recalls for GM trucks and SUVs of this period might have addressed issues like brake components or potential fire hazards. It's always advisable to check the NHTSA database for any applicable recalls based on the VIN. Long-term reliability hinges heavily on how well the vehicle has been maintained. A well-maintained 1981 Blazer can still be quite dependable, but one that has been neglected will likely require significant investment to bring back to good working order.

What Technology & Safety Features are Included?
The 1981 Chevrolet Silverado 1500 Blazer represents a simpler era of automotive technology, so expectations for built-in tech, entertainment, driver-assistance, and advanced safety features should be tempered.
Technology and Entertainment: Standard entertainment typically consisted of an AM radio, with an AM/FM radio often available as an option. Higher trims, like the Silverado, might have offered a more premium sound system, but features like cassette players or graphic equalizers were rare or costly add-ons. Air conditioning was a highly desirable optional feature that significantly enhanced comfort. Power windows and door locks were also optional luxury items not found on all models.
Driver-Assistance Features: In 1981, driver-assistance features as we know them today were virtually nonexistent. Power steering and power brakes were common, especially on higher trims like the Silverado, which made maneuvering and stopping easier for such a large vehicle. Cruise control was an available option on some models.
Safety Features: Standard safety equipment included three-point seatbelts (lap and shoulder belts) in the front, and lap belts in the rear. Disc brakes were standard on the front wheels, with drum brakes in the rear, providing adequate stopping power for the time. The Blazer's sturdy, body-on-frame construction offered a degree of inherent safety in a collision, providing a substantial barrier. However, airbags, anti-lock braking systems (ABS), and electronic stability control were not yet available.
Crash-Test Ratings: Formal crash-test ratings in the modern sense, with standardized procedures and public scoring, were not as prevalent or rigorous in 1981 as they are today. Manufacturers conducted their own internal testing, but comprehensive, comparable external ratings for vehicles from this period are scarce. The National Highway Traffic Safety Administration (NHTSA) did exist and conducted some testing, but data for this specific model and year may be limited or not directly comparable to current standards. Its weight and construction would likely have provided some protection in low-speed impacts, but passive safety technologies were minimal.
