Not meant to be adjusted, so not easily adjusted.
It is true that the ride height is not meant to be adjusted, but that doesn't mean that it CAN'T be done.
Above the rear axle, attached to the body of the car is a switch that looks like a small shock absorber. The end attached to the body can be adjusted by moving the mounting point. I would not recommend doing this. Small adjustments to this bracket or the switch could cause a failure of the air ride suspension, and could cause serious injury to people in the car if it failed while the vehicle is in operation.
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.
A 2000 Grand Marquis does not have struts, it uses a conventional shock/spring type suspension.
Rear suspension, on the control arm under the car just in front of the diff. This controls the height of the back end.
bend the arm
Depends on the Model. Some do, some don't.
Yes , there was standard suspension , sport / handling package , heavy duty suspension , and the air suspension
Sounds like you have a leak in the air suspension. Check out if it does or it will burn out the pump. Monroe makes a replacement set up for the " air -Ride". It runs you around a grand to have it replace the OEM design.
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)
Should be under the air filter box.
check under the glove 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 )
