The 1996 Chevrolet Blazer has 13 known issues compiled from NHTSA recalls, manufacturer TSBs, and owner forum reports. 7 issues are rated critical: ABS False Activation at Low Speed from Wheel Speed Sensor Corrosion and CSFI/CPI "Spider" Fuel Injector Assembly Failure (Poppet Valve Leaks) and Front Lower Ball Joint Premature Wear / Failure (Non-Greaseable) and 4.3L V6 Lower Intake Manifold Gasket Coolant Leak and 4.3L V6 CPI/CSFI "Spider" Fuel Injector Leaks and Poppet Valve Failure and Lower Intake Manifold Gasket Coolant/Oil Leak and In-Tank Fuel Pump Premature Failure and Stalling. Prospective buyers should inspect for these issues and factor potential repair costs into their purchase decision. Regular maintenance following the manufacturer's schedule helps prevent many common problems.
Repair costs for known Chevrolet Blazer issues range from $80 to $1,200, depending on the specific problem and whether you choose DIY or professional repair. The most critical issue, ABS False Activation at Low Speed from Wheel Speed Sensor Corrosion, typically costs $120-$600 to repair. Au7o provides step-by-step DIY maintenance guides that can help reduce repair costs.
On 1995-2003 Blazer/S10 trucks, rust and debris build up on the front wheel speed sensor mounting surfaces, increasing the air gap between the sensor and the hub reluctor ring. The weakened signal makes the Kelsey-Hayes ABS falsely interpret a wheel as locking during light brakin… Repairs typically run $120-$600. Severity: high.

The 4.3L Vortec uses a Central Sequential Fuel Injection (CSFI, often called the "spider") assembly buried under the upper intake plenum, with individual nylon poppet lines feeding each cylinder. The poppet valves and the integrated fuel pressure regulator crack, stick, or leak w… Repairs typically run $300-$900. Severity: high.
The factory front lower ball joints on the S-series Blazer were sealed with no grease fittings and cannot be lubricated, leading to premature wear. NHTSA complaints document serious failures where the ball joint separates, the wheel folds under the vehicle, and steering control i… Repairs typically run $300-$800. Severity: high.
The Vortec 4.3L V6 (like its 5.0L/5.7L siblings) used plastic-carrier lower intake manifold gaskets that erode and crack at the coolant ports from repeated thermal expansion cycles between the aluminum manifold and iron heads. Failures cluster between roughly 80,000 and 150,000 m… Repairs typically run $500-$1,100. Severity: high.
The 4.3L Vortec V6 used a Central Port Injection system (CPI 1992-1995, CSFI 1996-2002) with a central injector body and six plastic poppet lines — the "spider" — mounted inside the intake manifold. The plastic lines and nut-kit connections crack and leak raw fuel into the plenum… Repairs typically run $500-$1,200. Severity: high.
The 4.3L Vortec rarely fails head gaskets but very commonly fails its lower (plenum) intake manifold gaskets. The original-equipment gaskets use plastic/composite carriers that harden and shrink with heat cycling, typically leaking between roughly 100k-150k miles. Left unaddresse… Repairs typically run $600-$1,000. Severity: high.
Blazer in-tank fuel pumps fail well before normal service life — NHTSA complaints document failures from roughly 34,000 to 102,000 miles (averaging around 44,000 on the 2000 model year), often preceded by an erratic fuel gauge from the integrated sending unit corroding. GM produc… Repairs typically run $450-$900. Severity: high.
Push-button 4WD Blazers use an electric encoder motor on the NP1 electronic-shift transfer case, commanded by the Transfer Case Control Module (TCCM). The encoder motor's internal position sensor and gears wear out, and TCCM faults are equally common, so the transfer case fails t… Repairs typically run $250-$700. Severity: medium.
The S-series Blazer's Kelsey-Hayes ABS system is prone to age-related faults: front wheel-speed sensors (integrated into the hub bearings) corrode and give erratic signals, the EBCM ground at the radiator support gets rusty/loose, and later Kelsey-Hayes 325 modules can fail inter… Repairs typically run $150-$600. Severity: medium.
4WD Blazers with the electric push-button New Process 233 transfer case (RPO NP8) use a TCCM-controlled encoder motor to shift ranges. The encoder motor, its position sensor, corroded selector-button contacts, and connector moisture are all common failure points, producing a "Ser… Repairs typically run $250-$700. Severity: medium.
S-series 4x4s use a front axle disconnect operated by a vacuum-diaphragm actuator (or the notoriously slow thermal linear actuator on early-90s trucks) to couple the front axle after the transfer case shifts. The actuator diaphragm cracks and the small vacuum lines and switch ato… Repairs typically run $150-$500. Severity: medium.
The GM truck/SUV instrument clusters of this era use small air-core stepper motors to drive each gauge needle. Over time the internal dampening grease dries and the motors fail, causing needles to stick, read wildly wrong, or drop to zero. The speedometer and tachometer ("S" type… Repairs typically run $100-$400. Severity: low.
The heavy doors on two-door S-10 Blazers ride on small hinge pins with soft brass bushings that wear out — accelerated by lack of lubrication — letting the bushing holes in the hinge plates wallow out egg-shaped. The door then drops when opened, no longer aligns with the striker,… Repairs typically run $80-$300. Severity: low.
