It's the relays that go bad. It's supposed to be a fairly difficult repair from what I've read... Though if you're skilled and have highend equipment, I'm sure you can do it. Scottjoh repairs these for pretty cheap, you might want to just look into using his services.
If time is an issue, just grab one from a newer car and have it recoded (they're not tied to the VIN or anything, but there wrre minor changes throughout the years that can be accounted for through coding). From what I've seen, the newer ones are a bit more reliable
