Assuming that you mean "wiper blade" (blade and frame) which are replaced often rather than "wiper arm" (piece from the spindle at the hood to the wiper blade) which are rarely ever replaced, the 1988 Chevrolet S10 Pickup takes 16" wiper blades on both sides front. See sources and related links below for more information. Since there are over 22 different wiper arm attachments, do not buy wipers just by length only - be sure to lookup exact wiper blade part numbers by vehicle make, model and year for the brand wiper you decide to purchase. This ensures correct length AND correct attachment.
The 1988 Jeep windshield wiper motor is located on the firewall in the engine compartment. The wiper motor will be in the center of the firewall.
That depends on the make, but not likely with that many years in between.
