If you wish to disable an alarm beeper on a 94 Continental after it has beeped for two years but runs fine, place the key in the ignition and turn it slightly. Let the key stay on for 10 minutes before starting the vehicle completely.
I would buy the conversion kit and get rid of the air bags.
I have had the air bag changed 3 times over 6 years and they still do not work.
In hindsight i would have converted to springs and saved a lot on off road time and thousands of dollars.
Some second party vendor make the makes and the pumps (the pump blow after the labor to keep a leaky air bad inflated). I have purchase many leaky air bags and pumps.
Best bet THE DEALER they were going to charge me $1400 because they MAY get it right. Or at least when you retun over an over, to replace the leaky bags burned out pumps motors: you will not feel bad for the mechanic!
Check the battery it may be low or need replacement
If you own the car look under the hood and there should be a diagram showing the belt path and what pulleys to capture and which one is the tension release pulley.
The engine is running lean www.obd-codes.com this will help .
