1985 GMC S15 Jimmy Service and Repair Manual
This factory service and repair manual for the 1985 GMC S15 Jimmy covers the two-door sport utility across four trims — Base, Gypsy, High Sierra and Sierra Classic — with two gasoline engines behind them: a 2.8L overhead-valve V6 of 173 cubic inches and a 2.5L overhead-valve inline-four of 151 cubic inches.

Known issues on the 1985 S15 Jimmy. One recall is on the federal record, covering replacement lamp assemblies sold for these vehicles that were built without the amber side reflectors federal lighting rules require, which leaves the vehicle badly marked to traffic approaching from the side. One owner complaint is also logged, and it concerns the seats. Lighting circuits and seat hardware are both covered here, with wiring diagrams and diagnostics for the exterior lamps and removal, installation and torque procedures for the seats and their mountings.
