I drive a 2002 ford explorer eddie bauer edition. The car is making a thumping noise in the rear top drivers side. Sounds like a motor or heat of ac not but not sure. It is on all the time. also the door ajar light will not go off and it takes a long time for the lights to go off when you first leave to drive and also when you turn car off and get out.

Answers from the Automotive Experts

Amanda J. Pierce, MBA Lynn, You may need to have your suspension inspected for the thumping noise. Door ajar light stays on possibly because of the rear hatch, the sensor may be damaged. Lastly, your lights are on a delay for a safety feature where you may be able adjust the delay.

Helaine Kurot, Owner/Technician at 360 Automotive The door ajar light should be relatively easy to diagnose with a factory level scan tool. It will give the tech a good starting point to find out which door switch is not functioning properly. As long as it thinks a door is open, the lights will stay on until they time out. As far as the thumping noise from the rear of the driver side, there is a rear HVAC unit behind the back panel. These do have actuator/blend door issues which may be the cause of what you are describing. This may be a time intensive issue (you may want to drop the vehicle off at the shop instead of waiting for it) as the HVAC box may need to be disassembled to see whats going on inside. If you turn off the rear climate control does the noise go away?

Maryann Croce, Owner at Croce’s Transmission Specialists Lynn, On your 2002 Ford explorer. You may have more than one issue. The door ajar light could be a bad door ajar switch or a wiring problem. The noise coming from the rear passenger side may be a blend door motor. It opens the vent for heating / cooling. They do wear out. This is a common needed repair. Good luck.
