The 5-door Explorer and its companion the Mercury Mountaineer were redesigned entirely for the 2002 model year, gaining a similar appearance to its big brother, the Ford Expedition.
Run down to Walmart/Autozone and grab a can of white lithium grease spray (not silicone spray). Spray the door catch real good and open and close your door a few times to work it in.
Hi @sean25912
Please verify whether you mean the driver door key lock or the door outside handle is not working?
