I have a 95 firebird & I'm getting a series
of electrical problems
1. the most common I'm seeing door auto door locks ..drivers side opens but won't close
passengers side will close but needs finger action to open it.
2.Driver side auto window shut down after a month of intermittent working.
3. light on steering wheel control(left side of wheel) no longer lit but controls work.
4.Horn is no longer working & with all this snow up here in New Jersey my voice is giving out.
I noticed under the dash there is some sort of interface that could use a diagnostic tool
any one know where this tool can be purchased at a reasonable price & is it worth getting?
