Customer Question

I'm travelling out of town with my 2009 Mercury Marquee. I started getting a gairly constant, slow-rythmn beep coming out of my dash somewhere. No other signs of trouble - what the heck could it be?
JA: Will the headlights turn on? Is the battery fully charged?
Customer: Yes and Yes
JA: What is the model of your '09 Mercury?
Customer: Mercury Grand Marquis (sp?)
JA: What year is your ''09 Grand Marquis?
Customer: 2009
JA: Are you fixing your vehicle yourself? What have you tried so far?
Customer: I'm travelling so I haven't tried anything. ANd I wouldn't know what to fix since I don't know what the beeping sound is. Never happened before
JA: Anything else you want the mechanic to know before I connect you?
Customer: no --thank you

Do you have any warning lights that are on on the dash such as the check engine light, or srs?

Customer: replied 9 months ago.
No - there is an tire air sensor warning that is on at all times -- it broke over two years ago and has been on ever since. It has never beeped or made any sounds.

The beep that you hear is from the body control module. The beep will be the control module beeping out he codes for the tire monitor system. There is nothing to worry about.
