92 mustang LX started beeping when started

amfw · 01-21-2008, 02:52 PM

Help! It beeps like a microwave that's done----5 short beeps, a pause then again 5 times total-20 beeps, then it stops and won't do it again until I start it up again....plus, it's intermittent, doesn't do it all the time....I've had it for 7 years and it's never done it before----I just passed 86,000 miles....Anyone know what it is? It sounds like it's coming from under dash near radio and glove box!!!!!!

thanks, AMFW

my car is doing this as well its also a 92 lx the beeping is coming from a light blue box behind the ac control above the radio.it has 2 connectors on one end. one is black the other is gray.on my car the air bag light was on.while working on the heater i noticed the gray connector was unplugged so i plugged it back in .and now the airbag light has gone off but im getting the same beeping coming from the box.i dont know what the beeping is caused from but the blue box has something to do with the air bag.you can unplug the gray connector and it will stop the beeping with no other side affects besides the light coming on and your airbag not working.im thinking of asking ford what the beeping means.if i cant find out there is a small hole in the box where the speaker is for the beep.im going to either open it up and cut the wire or put some tape over it to muffle it

Sounds to me like you have plugged in something that does not belong to that year of car.

Do you have a gas gauge that does not work?

My son once had a 91 LX 2.3 that had that beeping thing going on and
the gas gauge did not work. So we replaced the whole instrument cluster from a known 91 parts car and both the the gas gauge started working and the beeping went away. The previus owner did admit to replacing the speedo cluster when the speedometer died.

We suspect his replacement came from the wrong year
