If it is your compressor there is something causing it to be overworked and die out on you. Possibly a hole in the line or the air bag somewhere. You can save yourself time, money and headache by visiting and ordering a conversion kit for your vehicle. You will be glad you did and your car will ride like new again.

2010 gran marqs battery keeps going flat after sitting for a period of time, changed battery still the same

You need to find the Electric draw in the system. The first thing would be a Diode test on the Alternator. Free upon request at Autozone, Advance, or Oreilys.

If you have Air-Ride suspension, turn it off overnight and see if car height deflates and the Battery stays up. A little harder to check would be the Rear Window defroster which can activate without an indicator light showing.

After that, suspect a hanging Relay, which is continuing to supply power after the Ignition switch is off.

The Dealer has a machine which plugs in between the wiring harnesses. Since some connectors have 100 pin connectors a great deal of test time is saved by testing 100 circuits at once instead of manually testing them 1 by 1.

The air bag light on my 2003 Mercury Grand Marquis LS Ultimate Edition blinks 3 times then goes out,then does this a couple more times,then stays on constantly.Any ideas?

There appears to be a pattern of premature failure of seatbelt pretensioners in the mid-2000s Gran Marquis, especially the 2005 model year. See or NHTSA complaints. Ford dealer wanted $103 for diagnosis and $501 for replacement of the part.

I have a 1994 Gran Marquis. Fuel lines are rotting and leaking

Just get a piece of the rotting fuel line so that you will be assured of getting the right size. Take it to a shop that sells car accessories, and ask them for enough to do your car. Also get new clamps. Start at the fuel tank, undo the clamp, pull off the old hose , put on the new one, do up the new clamp, and then just follow the old hose along, replacing it with the new one as you go. At the far end. do the same... undo the old clamp, put the new hose and clamp on. But I forgot to tell you about the fuel filter. Replace this while you are doing this job.
