Best to look under the back of the car to see if it has air springs.
I have a 1998 ford grand Marquis- and the problem is the air suspension light stays on- how to fix this problem
The 1999 Mercury Grand Marquis air suspension relay switch can be found on the firewall in the engine compartment. The air suspension relay switch will be on the passenger side of the firewall.
To disarm your airsusspentoin . theres a switch on the left side of your trunk when you open it.
I have a Grand Marquis and shortly after I start the car you hear a sound coming from the the engine side and that is the rear air suspension lifting the car up(the sound is the air being pumped into the airsuspension to lift the car)
Yes , there was standard suspension , sport / handling package , heavy duty suspension , and the air suspension
Depends on the Model. Some do, some don't.
under the air filter box
check under the glove box
Should be under the air filter box.
According to the 2002 Mercury Grand Marquis Owner Guide : The ON / OFF rocker switch for the rear air suspension is located : ( in the trunk , on the drivers side of the trunk , the Owner Guide shows that there is a label next to the switch )
A 1996 Mercury Grand Marquis COULD BE equipped with the rear air suspension ( if it is then there will be a rocker style shut off switch in the trunk , any time any of the wheels is off the ground you need to shut off the air suspension system ) * I believe the switch and label is on the passenger side of the trunk on the 1996
These cars have air suspension when they are built in the factory. Likely someone has taken the air suspension out, and left the sensors there, causing it to detect a problem. Not a serious thing.
