  • cooling fans wont turn on

    i recently bought a 1995 firebird formula and am having some problems with the cooling fans. they dont seem to come on. i have check the fuses for the fans and they all seem fine. the temp goes past the 226degrees which is when the first fans is supposed to come on. is they any other fuses/ relays or systems i need to check. thanks

    Check Shoebox's online wiring diagram for your 95:

    Note that there are two variations used in 95 for "early" and "late" models. Have you scanned for codes?

      Check your relays in your fuse box. I had that same problem and thats what mine was.

        ditto on that for me. Replaced a fuse and turned right back on.

          i forgot to mention that the a/c doesnt work either. i have read in some post that if the fans dont work the a/c wont kick on either. is there anyway to tell if a relay is bad. also the cigarette lights stopped working also. thanks for the help
