2003 Ford Explorer Sport Trac 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 composite (plastic) intake manifold may crack near the thermostat housing and cause a coolant leak. Ford released an updated manifold that was reinforced to prevent a recurrence. No recall was issued for this problem but Ford did extend the warranty to seven years on some models from the date of purchase.
A rattling noise from the engine may indicate that the timing chain cassette is worn. Our technicians tell us that installing an updated cassette and timing chain tensioner should correct this concern.
2003 Ford Explorer Sport Trac QuestionsI'm driving and it just died i heard a click seemed like an electrical problem. Coasted over tried to start wouldn't. Batterys charged. (2 answers)
I have had recent electrical done work under steering wheel in the where the electrical system is. For the anti theft device it kept my truck from starting randomly. It stopped but was never fixed just stopped however when it' did stop now the blinkers won't turn off automatically.
My sport trac will start if it sits overnight. I start it up it the morning and runs fine. If I drive to a few other locations, after the last location it will not start. It tries to turn over, but will not. I have to let it sit for a while, at which it will start.
Concerned about having correct mileage on the new odometer.
Thanks in advance
