2002 Mercury Grand Marquis Air Suspension Compressor Parts Questions & Experts Answers

• Q: How to Service and Repair the Air Suspension Compressor on 2002 Mercury Grand Marquis?

  A: Begin all air compressor maintenance by disabling the air suspension switch on the left-hand side of the luggage compartment so that the vehicle stays safe from damage or injury. Start by unfastening the ground cable of the battery before extracting the Engine Air Cleaner (ACL) and air compressor drier cover by dislodging their pushpins. The removal process starts with first eliminating the snorkel pushpin followed by taking away the snorkel. A user must start disconnecting the air compressor by compressing the quick connect locking ring then pulling out the air line before disconnecting the wiring. The vehicle needs to be raised then the nuts must be removed before lowering it to extract the air compressor. A minimum 3mm (1/8inch) length of visible white air line should be inserted into each fitting when processing air lines for the compressor drier. The vehicle will show unusual driving behavior after battery disconnection and reconnection since it needs to learn its adaptive strategy through driving at least 16 km (10 mi) before gaining proper control. The installation process of the air compressor requires inflating the air suspension system afterwards. The installation process ends through execution of the uninstallation sequence.
