1991 Ford Explorer ProblemsHeater Stuck on Hottest Setting Due to Broken Heater Blend Door
A failed heater blend door or actuator can cause the temperature control for the HVAC system to stop working. A clicking sound from the dash area would commonly indicate an actuator fault. If the heater gets stuck on the hottest setting, the heater blend door may be broken requiring replacement of the heater box to repair the issue.
The radius arm bushing may wear, causing a clunking or popping noise when driving over bumps. To repair, the bushings need to be replaced. Depending on the severity of the wear, the brackets may also need replacement. Driving with worn bushings will shorten tire life and cause tire cupping (uneven tire wear).
If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.
