Some Ford Explorer owners report experiencing issues with their heater, which only works while driving and blows cold air when idle. Common reasons for this problem include low coolant levels, which are essential for transferring heat from the engine to the heater core. Additionally, some owners have found that a clogged heater core can prevent proper heating, as it blocks hot engine coolant from warming the cabin air. Air pockets in the cooling system may also disrupt coolant flow, leading to inconsistent heating, and bleeding the system can help resolve this issue. Furthermore, a malfunctioning thermostat may prevent the engine from reaching the optimal temperature needed for cabin heating. Other potential causes include a bad heater core, an airlocked cooling system, a faulty blend door actuator, a sluggish blower motor, or a malfunctioning thermostat. To address these concerns, it is advisable for owners to check the coolant level, inspect the heater core, bleed the cooling system, and ensure the thermostat is functioning properly. If these steps do not resolve the issue, further diagnosis by a qualified mechanic may be necessary.

Some Ford Explorer owners report experiencing cracks below the rear window of the liftgate, which are a known issue in certain models. These cracks can result from stress, pressure, or structural weaknesses, raising safety concerns as they may compromise the liftgate's structural integrity and overall vehicle safety. Depending on the severity of the crack, repair options may include welding, patching, or replacing the damaged part. It is advisable for owners to seek a professional inspection from a qualified mechanic or body shop to determine the most effective repair solution. Prompt attention to this issue is crucial for maintaining the safety and functionality of the Ford Explorer.
