I know no one will respond to this but what the hell..i have a 1986 firebird and i installed a rear hatch release switch and relay..but the rear hatch wont release...what is the problem???..the relay clicks on and off and nothing happens..Anyone have a answer

 

I believe you need to get a part for the rear, a solinoid or something.
here's an article for installing one on a 90-92 but should be basically the same for a 86.
