So either we have a huge coincidence here, or you totally FUBAR'd your car when you were working on it.
Is it possible that you shorted out some wires? Did you disconnect the battery at any point? Please tell us in detail what *exactly* you worked on, which wires you touched, which panels you removed, etc.
Check fuses - maybe you have a blown fuse.
Beyond that, figure out exactly what is and what isn't working. Go through all of the electronics one by one and get back to us. You may have toasted your front SAM module.
Just to comment on your last thread - sending out your airbag module is a very bad idea. It will not fix the problem because I very much doubt the module is bad - they go bad EXTREMELY rarely.
These sorts of electrical problems are usually very hard to diagnose, even at the stealership with Star Diagnostics at hand.
