[QUOTE="ZeroDCX, post: 14338777, member: 91953"] I actually purchased my set at an Autozone, but I'm sure you can get them cheap from Harbor Freight or something of the sort. Any auto part store should carry them. No prob. If you're absolutely (and I mean absolutely) sure of this, then you can remove the affected Metal Oxide Varistor (MOV40). Attach it back to the car (it must be in mounting position since its mounts are used as a grounding source), replace Fuse 4 (10A) underneath the dash and turn the ignition on (don't start the car). The MOV protects other components within the module from damage due to voltage spikes by clamping voltage and acting as a sacrificial fuse in the event of such an occurrence, so the module's components that are supposed to be protected by MOV40 will not be protected from voltage spikes (hence why I say not to start the car). If it flashes with Code 52 then you've found your problem. But I would replace the varistor if I were you, better safe than sorry. Code 52 can be cleared by using the diagnostic connector underneath the glove box area. Good luck. Edit: Even-though this should not be an issue since the airbags are actually hardwired to the front impact sensors. If you wish to play it safe, you could always disconnect the airbags first before attempting this. But then it would also display different codes for the airbags (Code 32/33). Just as long as it doesn't read out Code 12/13 and blow the number four fuse you should be good to go assuming you had the same issue I did. [/QUOTE]
