I need instructions on how to change the headlamp bulbs on a 2005 grand marquis. Please help.

Does your Grand Marquis have head lamps with auto lamps ? Which fuse keeps blowing ? Could be a shorted LCM - lighting control module ?

Lighting Control Module (LCM)
The LCM eliminates the electronic interference and heat associated with the thermoelectric devices used previously. The LCM is a microprocessor-based module that controls several vehicle subsystems. It responds to electrical input signals from various switches, sensors, and external modules..

When you open the hood you will see a cover where the hood latch is. Some covers have individual doors on each side of the hood latch. If you have that type just pop the release on the cover and reach down to the headlamp bulb. It comes out with a twist with the socket and then pull the bulb free. Use a kleenex or gloves to install new bulb and reverse the process.

If the whole panel is one piece there are some plastic button holders to remove to lift the cover. Your headlights are underneath. In some cases the passengers side headlight may require removing the battery to access. Then just twist the socket and remove the bulb afterwards, then reverse process.

3 bolts on top. 10 mm wrench I think. Locate the bulb, Turn 1/4 turn and replace the bulb. Sylvania 9007's
