2002 Chevrolet Wiring Diagrams

Introduced in 1985 as a rival to the first front-wheel-drive Chrysler minivans, the midsize, truck-based Astro was Chevrolet’s original entrant into that market. The Astro is still available with either rear-wheel drive or all-wheel drive, and it is positioned between Chevy’s front-drive Venture and full-size Express.

Is it a four-door pickup truck? Or is it a sport utility vehicle that happens to have an open cargo bed? The Avalanche is both and more. Chevrolet calls it “the ultimate utility vehicle” — a designation also given to the Lincoln Blackwood, which is also new for 2002. In fact, Ford was first with the basic idea by launching its Explorer Sport Trac in 2000. Cadillac joins the fray in January 2002 with its new Escalade EXT. All four are considered crossover models, which combine the benefits of flexible passenger and cargo configurations in a truck-based vehicle that’s designed for heavy-duty tasks.

Despite the debut of the new midsize TrailBlazer, Chevrolet expects to keep the smaller, prior-generation Blazer in its lineup until at least 2003. The TrailBlazer name was previously used on step-up Blazers. But GMC dropped its Jimmy — the automaker’s equivalent of Chevy’s Blazer — when it introduced the midsize 2002 Envoy.

With a history that dates back to 1967, Chevrolet’s rear-wheel-drive muscle car is finally facing the end of the line. The 2002 model year is the last one for both the Camaro and the related Pontiac Firebird. Camaro sales have been on a downhill slide since 1994; they were up a bit in 2000 but then plummeted by 16 percent to 35,453 units in 2001, according to Automotive News. Rumors of its extinction have been circulating for several years, and they’re finally proving to be true. No replacement is planned. The Ford Mustang, archrival to the Camaro and Firebird, has been outselling the muscular GM duo by far.

A new LS sport sedan and LS sport coupe join General Motors' best-selling car line for the 2002 model year and are equipped with a new EcoTec 2.2-liter four-cylinder engine that makes 140 horsepower. A sporty Z24 sedan joins the Z24 coupe, and both are fitted with a 150-hp, twin-cam four-cylinder; they will be available for a limited time. The base Cavalier, which uses a 115-hp engine, can have an optional Sport Package.

More power is the byword for the 2002 Chevrolet Corvette — at least for the top-performing Z06 coupe, which debuted last year. Chevrolet’s regular 5.7-liter LS1 V-8 engine stands pat at 350 horsepower, but the LS6 edition in the Z06 coupe has gained 20 hp and now cranks out 405 horses. That makes the 2002 Z06 the quickest, most powerful Corvette ever.

Similar to the GMC Savana, the Express is Chevrolet’s full-size, rear-wheel-drive van, which is mounted on a full-frame chassis and is available in two sizes. Like its rivals from Dodge and Ford, the Express van has been around for decades — since 1964, to be precise.

A new Sport Appearance Package for Chevrolet’s largest passenger car includes different taillights, special gauges and 16-inch pace-car aluminum wheels. A cassette stereo with Radio Data System (RDS) operation and driver/passenger temperature controls are standard for 2002. New LATCH child-seat tethers also are installed.

Conservative in appearance, Chevrolet’s mainstay, bread-and-butter midsize Malibu sedan accounts for plenty of sales each year. The total dipped a little in 2000 to 207,376 units, but that figure still makes the Malibu a major player in the market.

The two-door Monte Carlo coupe has served as Chevrolet’s entrant into NASCAR racing, though the stock car has nothing mechanically in common with production models. The 2000 models received bold, race-inspired restyling, which moved them from midsize to full-size proportions on a new platform. These changes created a dramatic look that belies the Monte Carlo’s kinship to the four-door Impala sedan, yet both vehicles ride the same front-drive platform and employ the same V-6 engines.

A near-twin of the Toyota Corolla, Chevrolet’s subcompact front-drive four-door sedan will fade away after the 2002 model year, when Toyota switches to a new Corolla generation. Both models are built at a California plant that General Motors shares with Toyota, and only minor styling and equipment differences separate the two sedans.

A third door is now standard on extended-cab versions of Chevrolet’s compact pickup truck, which eases loading and access to the cargoA third door is now standard on extended-cab versions of Chevrolet’s compact pickup truck, which eases loading and access to the cargo area on the driver’s side. Air conditioning and a tachometer have also joined the standard-equipment list. The two-wheel-drive, regular-cab, long-bed S-10 has been dropped.

Last redesigned for the 1999 model year, Chevrolet’s full-size pickup truck gets upgraded emissions control systems and some repackaged options for 2002. All models now have a chrome bumper and grille, while extended-cab pickups are now available with an automatic transmission only.

Though it’s not the biggest sport utility vehicle, the Suburban clearly warrants a king-size designation. Chevrolet has used the Suburban name for a utility wagon since 1935. Last redesigned for 2000, the super-size SUV is a close cousin to the GMC Yukon XL, which used to be called the GMC Suburban. Available with two-wheel or four-wheel drive, the Suburban is built on the full-size Silverado pickup truck platform, which is also used for the Chevrolet Tahoe and GMC Yukon SUVs.

Based on the Silverado pickup truck, Chevrolet’s full-size Tahoe is the less-gargantuan kid brother of the king-size Suburban. GMC produces a near-twin called the Yukon, and both models compete against the Ford Expedition and Lincoln Navigator.

Available in two-door convertible or four-door wagon form, this compact sport utility vehicle is Chevrolet’s version of the Suzuki Vitara. Alloy wheels are new for 2002, and the LT edition loses its running boards. A CD player is now standard on all models, and four-door versions gain a roof rack. Other new amenities include front armrests, “see-through” halo headrests and adjustable lumbar support for the driver.

Size matters when it comes to sport utility vehicles, and midsize SUVs are the ones that capture the heart of the market. General Motors launched three new midsize models by spring 2001 as early 2002 models. Chevrolet’s TrailBlazer is one member of the trio, which is especially crucial to GM because of the debut of the redesigned Ford Explorer. Oldsmobile offers the luxury-oriented Bravada and GMC has the new Envoy, both of which are similar to the TrailBlazer in structure and appearance. Despite the emergence of this all-new TrailBlazer, Chevrolet expects to keep the prior-generation Blazer in its lineup until at least 2003.

Closely related to the Oldsmobile Silhouette and Pontiac Montana, the Venture is Chevrolet’s front-wheel-drive minivan. For 2002, the Venture adds an all-wheel-drive option. Ever since its predecessor, the Lumina APV, was introduced in 1990, Chevrolet’s version has been the lower-priced, value-oriented member of the GM trio of front-drive minivans.
