Known issues on the 1985 S10 Blazer. Three recalls are recorded federally for the 1985 Blazer, and all of them cover replacement lamp assemblies sold without amber side reflectors, which reduces how visible the vehicle is from the side after dark. Fifteen owner complaints follow, the largest share on the power train with five, then engine and cooling with four and seat belts with two. The transmission and transfer case procedures, cooling system testing and belt anchorage specifications in this manual address those three areas directly.
