Known issues on the 1984 Eldorado. Three recalls are on federal record for this model year. The first covers the vehicle speed control: a small nylon bushing in the cruise control servo bail may slip out of place, allowing the servo rod assembly to catch on engine components, with the potential for a stuck throttle and a vehicle crash. The second covers the front bucket seat back locks, which do not conform to Federal Motor Vehicle Safety Standard 207 (anchorage of seats), so in a crash the seat back lock may not function. The third covers the power window switch assemblies, where water or snow dripping onto the driver's side window switch may cause an electrical short and the switches to overheat, which could result in a fire in the door panel area. Owners have filed 9 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

From a cruise control that won't disengage to a seat back lock or a window switch pulled for inspection, it keeps you on the OEM procedure and the correct specification for your specific 1984 Eldorado.
