Hello Deborah, If your car has air ride suspension, it could be an air pump turning on and off. Since it goes on and off so often, it might have an air leak in the system.

SOURCE: My 98 Cadillac DeVille rear air suspension system

Common problem on all air suspension vehicles. It could be that there is a hairline crack in one of the shock bladders or that the pump is just too weak to pump up to it's intended pressure, a sensor or solenoid could also be bad.

Whenever I run into this problem I order a spring conversion kit for that vehicle, it is usually not worth spending $3000+ to repair the suspension.

www.Strutmasters.com sells the best kits, $327.00 for the rear. It also comes with a resistor so that your suspension light is not on.

SOURCE: 1999 Cadillac Deville - How to replace fuel pump?

Hello,

Unfortunetly Cadillac does not have an access panel for fuel pump access until the newer years. You will need to drop the tank. Also, don't let the tank come slamming to the ground, make sure you take it slow so you dont dammage the lines to the sending unit.

Good Luck!

That is the compressor for the rear air shocks. If you stop hearing this noise then something is wrong. It levels the car when running.

I am writing asking for help to address what I consider an unacceptable response from a Cadillac mechanic when asked to evaluate a valve-like noise coming from my 2008 SRX Cadillac NorthStar VVT V8 engine....


What type of gas are you running in the north star? what you describe sounds like a valve rattle from preignition what i would do 1rst is fill the car up with premium gas (93) octane it will be expensive but a lot cheaper than running to the dealership drive the tank till empty and then resume as you were if this solves your problem you just saved yourself a few hundred dollars if not go to someone like auto zone and have a diagnostic done to see if any codes are stored there may be something with the timing of the anti knock sensor could be bad i would try these steps first before spending all of my money at the dealership if all else fails you can call gm yourself and see if they are having similar complaints from other customers. hope this at least get you started on the right road.

92 cadillac deville- back seat floor boards fill up with water (rain?) front floors and trunk are damp, have cleaned seals around doors, trunk, hood, etc but back seat floors still fill up almost to the...


Water leaks can be really evasive, It could be coming from the rear glass where it seals against the body or it could be coming from the seams where the quarter panels and roof panels meet. (at the lower corners of the back glass/trunk lid area.) The best way to find these things are to water-test the vehicle. You can look for water entering the trunk area if you can find someone you trust to run water over the trunk and back glass area while you are inside the trunk with a flashlight. If this does not yield any answers, it may be necessary to remove the rear seat and interrior panels and headliner to look for water running into the cabin area. If you see any water, follow it uphill to locate the point of entry. I have even seen windshield area roof leaks fill the rear floor pans of a car that was parked nose-up on a hill.

Water leaking on headliner


The hoses for your sun roof run down the front pillars. You may have clogs in the rear hoses that go down into the trunk area and when you move and stop the water rushes to the front hoses and run down. Gurgling is a good noise that the hoses are moving water. I would have all your hoses checked and flushed. The back hoses are most likely cloged or damaged.
