break & air bag lights stay on

I have a 1998 intrepid. The break and air bag lights are staying on and the power windows, heat, a/c and blinkers stop working. This was happening intermittently a couple of months ago and I had the ignition switch replace. Now it is happening all the time. HELP!!

One of two things has probably happened, you have a bad connection at your main bulkhead connector or you have a bad ground, I'm leaning towards bad ground. Try this, look along the bottom of the dash panel, behind the carpeting and behind the radio, A/C, etc. and look for a series of black wires bolted to the body. Make sure that they're tight and clean. That's a start.
