My old 93 mercury grand marquis has the airbag light on, it flashes in sequences of 5 and 1 the stealership wants $60 to diagnose but I figure it's probably flashing a diagnostic code and maybe somebody here can direct me what to do? I'd hate to spend a ton of money on a 11 year old car with 160K on it, hopefully it's a cheap fix.....probably not....

This is a educated guess.

Though not a Ford, one of my aged vehicle's air bag light would stay on for an extended time. I checked into it and found out that the bag was due to be repacked.

My Maxima has side airbags in the seats. A cd case under my driver seat knocked a cable connection loose and my airbag light started blinking.

On the max, there's a way to reset the airbag error code using a sequence of ignition key position and door switch activations - might be something like that on your car that you can use to clear the error.

Code 51: Diagnostic monitor internal fuse blown and short to ground no longer exists.
That is what the code discription says. Finding the intermittant short to ground and fixing it is what takes time and knowledge. I would get at least 1 hour @ $74.00 rate to check this.

I suspect the short is in the "clockspring" between the steering wheel and the column.
Where ever it is, it needs to be fixed BEFORE replacing the Diag. monitor or it will just blow again.

I will forgive the "stealership" remark...this time

where is the fuse and is it a special fuse? how is it replaced?

The fuse is INSIDE the monitor. You have to replace the monitor to fix the fuse.(on newer models it is a seperate fuse in the fuse box).
By chance did you see a code 13 or 14 flash at any time? 13 means short in airbag circuit and 14 means shot in crash sensor circuit. One of these codes usually precedes the 51.
You must fix the short before replacing the monitor or it will just blow again.
Monitor= airbag control module,btw.

Is the part expensive? Assuming the short is fixed easily how much should I expect this to cost? no other codes were noted. Wife was driving it though she may not have noticed.

My Ford Exploder's airbag light is flasing too, had it in and the tech wanted to do a diagnostic check but the husband just told me not to hit anything.

list here is 212.53 on the module and 95.16 on the clockspring wiring assembly.
May be differant in your area.
IF you need the clockspring(probably) the steering wheel has to be removed to access the part. That is about the hardest part of the job.

Thanx, and...ouch! Is it safe to disassemble this stuff myself or do I risk airbag deployment by working in the blind on it? Obviously I'd disconnect the battery....

Unhook the battery and wait about 5 mins. for the backup power to drain off and you should be good to go.
WHATEVER you do, don't stick a meter or anything to the airbag itself! KABOOM!

A $.99 roll of black tape is the cheapest "dash-light" fix I have found

damn, maybe I'll pay for it..... kaboom is bad....

btw, any chance if I leave it alone that the airbag will deploy while driving?
