Question about 2003 Lincoln Navigator
First of all, I'm not sure where the pump is located. Next the pump makes a deep pumping noise every few minutes whether it is parked or as I drive. Can I replace this pump? Is it a leak in the air bags. Is this noise suppose to be so loud?
I don't know how will this help, but you can check the car in the morning before you start it, look under it and check the level, is it dropped from the front or back. this way you can tell if you have a leak and where. if not then i think its the level sensor. in the 1998 you have two one in the front left. and one near the deferential in the back.
hope this helps you in anyway.
have a nice day.
