Known issues on the 1988 Wrangler. Two recalls are on federal record for this model year: a windshield wiper linkage that can dislocate and bind and, in inclement weather, reduce visibility; and an equipment item — the cockpit — that could strike and injure people outside the vehicle. Owners have filed 55 complaints and Jeep has issued 3 technical service bulletins for the year.
From a routine service interval to a hard-to-trace wiring fault or a stubborn driveability problem, it keeps you on the OEM procedure and the correct specification for your specific 1988 Wrangler.
