SOURCE: Air bag light
Usually a lit airbag can be attributed to faulty wiring, crash sensor behind the front bumper, bad connection between the airbag and lower part of the steering column, or a faulty airbag module. I've also heard of clockspring wiring harness problems. An airbag "on" light means that your airbag system is INACTIVE. Be careful. Check for a safety recall. You must have the battery disconnected for at least 15 minutes for a reset and double check your battery. I know it seems simple, but a poor battery will trip a code. 15 minutes allows the SDM (Sensing Diagnostic Module or Airbag computer) to discharge the backup power for airbag. Do this especially if you're poking around the controls. It sounds like a bad connection which is not allowing communication between all parts of the system. Also check the fuse (can't hurt).

SOURCE: check gauges light comes on
The PCM has the voltage regulator inside it that controls the charge from the alternator to the battery, unlike older vehicles that have the voltage regulator directly on the alternator. Also there is a battery temperature sensor under the battery that the PCM uses to decide how much to send the battery. Possibilities; bad alternator, bad PCM, bad battery temp sensor, bad battery, and bad connections. Battery tests are easy check when fully charged should get around 12.5v then turn on headlights for 2 minutes and check again should still be around 12v. To test charging system start engine and test at bettery terminals should get 13-15v if not then something wrong with charging system take alternator to advance auto and they will test it for free if its good you are down to connections, PCM and battery temp sensor. test battery temp sensor at 75 to 80 degrees fahrenheit should get 9000-12000 ohms resistance (9k-12K ohms) if thats good check ground connections on vehicle body , connections on alternator, and plugs into pcm as well as the two above it (depending on model and year). If all that is good your PCM is bad get one on the internet preprogrammed for your vin number for $250 if you get one at the parts store it is $250 and then you have to get it programmed about another $80. You can also test the alternator your self by disconnecting the 3 tiny nuts and removing the connection from the field terminals (plastic piece with two terminals) and checking again at battery for 13-15v ( stay away from pulleys and belt,no loose clothing or long hair if you value your health). The PCM shorts the field connectors to regulate the voltage so removing that connector eliminates the PCM , battery temp sensor and the wire to and from them.

It sounds to me like you have a hole or cracks in your airbag. The dealership typically diagnoses it as the compressor but that is only to keep you coming back and wasting more money on something that will never truly be fixed. The Compressor is the problem but the airbags are bad as well. When the air bag has a hole or leak in it the compressor has to work extra hard because it is like blowing up a balloon with a hole in it. Therefor the airbag will kill the compressor. It sounds like this is what happened. I would recommend going to strutmasters.com and taking a look at our conversion kits. these convert you from the airbag to a powder coated American made steel coil spring that is guaranteed to last the life of the car. This is a PERMANENT fix and ALOT cheaper than going to the dealership. I added the link below so you can check it out. http://www.strutmasters.com/ford-suspension-parts-s/75.htm I hope I was of some help Good Luck!!!
