Explorer, which replaced the Bronco II; six-and-a-half years after the segment-leading Cherokee debuted with four doors. The upscale Oldsmobile Bravada appeared later in the year featuring an All-Wheel-Drive package called "Smart-Trak" (using a BorgWarner 4472 transfer case, shared with the AWD Astro/Safari). 1992 models were similar to 1991s - the only way to tell the difference is the rear back glass (the rear glass does not have any trim to which two black buttons serve as the back glass strut mounting points) and front grille (chrome shell with argent silver inserts). The interior was a carryover from 1991 with the exception of the center console and steering wheel (X-bar style similar to the one used in the GMT400 trucks). Also, the "S-15" name was dropped from the Jimmy. The S10 Blazer also introduced an upscale Tahoe and Sport trim packages, the Tahoe LT, which was rebadged as the LT in 1995 whilst the Tahoe package was renamed as the LS.

Body trim included also black plastic fender flares, front fog lights and spare tire carrier on the tailgate. 1992 was the first model year where the S10 Blazer and Jimmy offered an NP233 electronic transfer case for as a drivetrain option. This deleted the Manual gear range selector with a 3 position switch located to the left of the gauge cluster in the same location that the rear defrost button would be located on non-electronic transfer-case and 2WD model Blazers and Jimmies (when optioned with the electronic transfer case the defrost button assembly is positioned below the headlight switch). The electronic transfer-case added luxury however there was no neutral position with the electronic transfer case, so the owner's manual stated that the drive shaft had to be removed when the vehicle was being towed. The fuel lines, which were routed on the driver side frame rail to the TBI fuel injectors, were redesigned where the fuel inlets entered the rear of the engine (same as the GMT400). This was phased in because of the L35 option which used a similar fuel line setup. The serpentine accessory drive for the 4.3L motor
