Question about 2003 Lincoln Navigator

1 Answer

Loud buzzing noise

My 03 Navigator is making a loud buzzing noise when the engine is first started. It makes it whether the AC is on or not. It stops when you start driving, but sometimes comes back on while driving as well. It also comes on with the key in power position but WITHOUT the engine actually being started. It almost sounds like an electrical noise.

From the sounds of it, it's simply your air ride's compressor. If you're not aware that your vehicle has air ride suspension, read up on the user's manual or look on the web. When you start your vehicle and shift into drive or reverse, your compressor should start (assuming no doors are ajar). The compressor than fills all four airbags in your vehicle to a factory-set height. These airbags provide a softer ride than the conventional shock/strut system seen in less expensive SUV's and trucks but are also more prone to problems and damage down the line. You can isolate the compressor as the sound by going to your truck, removing the left hand side panel and switching your air ride off. Your car's compressor then should not kick in at all. However, you should not operate your vehicle with this switch turned off. You should only use it as a diagnostic reference or anytime your car is towed, hoisted, or jacked up. Hope this helps.

More info - If it only makes the noise when the car is moving its probably a wheel bearing - if it makes a whining noise whether its moving or not it sound like the power steering pump is on its way out - it could be as simple as adding fluid - start the vehicle and while sitting there turn the wheel left and right - the noise should get louder and softer - if it doesnt - its one of the other accessories - a/c pump or the alternator itself -

Your AC compressor on the engine is the likely problem, either the pump is frozen up or the front bearing is frozen up, don't run the system or the belt will burn and fly off and strands you. Get this taken care of right away before winter. Have a local shop listen to the noise to confirm my guess as to the cause.

98 lincoln navigator loud noise, shaking, high rpm at idle, drive


I don't know how much oil you had to put in but it sounds like you have maybe more than opne issue and both sound major. One is engine reving and speed not picking up sounds like trans problem. Two the engine shaking and making noise and being run low on oil leans toward possible engine damage. If your mechanicly inclined check all fluids and when checking trans fluid smell it. If it smells burnt the trans has been damaged. Check oil pressure and make sure coolant is full.You may have to take it into the shop.
