I've been told to replace coils. That's what I'm doing this weekend. Hopefully that & a full tuneup will fix it.

2007 Mercury Grand Marquis. Where is the security system fuse located on my vehicle.

Question edited for clarity, FULL 'year make model'.
Question moved to model category.

There isn't a fuse. If there was, someone could break the window, open the door and quickly remove the fuse. The anti-theft security system is a complex system involving the antitheft module, sensors, the ECM and the BCM. They are computers that can't be reprogrammed to remove anti-theft feature.

'Thinking' is not good. What brings you to this conclusion? There are ways to check for parasitic draw and thinking is not one of them :>D

You need a good auto-electrician with a pro grade scan tool computer.

1998 grand Marquis blows out Fuse 13. This shuts off power to the instrument cluster and shutting the Headlights, only when the Variable Control iss in the "Auto" position. In the "On " position th

(1998 Gr. Marquis) I just found the culprit of my fuse #13 for the speedo, temp and votage gages. I had to remove the gear shifter cover which was not difficult also the metal brace across the bottom and the ignition key, but it was a tiny exposed burr in the overdrive shift button wire just at the end of the gear shift leaver. I elec. taped it up and now, no more blown fuse!

I have a 2003 mercury grand marquis and my blower motor does not work there is no voltage at blower motor plug checked fuse already and that is good and checked the relay they were both good

voltage comes from the actual a/c head,chek a wiring diagram to see which actual wire brings pwr down to ur blower . access by removing a/c head out to access backside connectors. another common problem overlooked is to to check ur blower resistors their located in the same area as ur blower motor. u have to access the two mounting bolts that hold it in. the pigtail/wires that connect to blwr mtr usually come from this resistor pak located in blwr hsg to help keep em cool.wat they do is vary the amount of ground going to blower mtr.wen u remove it a telltale sign that thir no good is severe rust buildup on the mounting plate or electrical module wrapped in sealant. good luk
