      Check to see if you are getting 12v to the battery terminal in the engine compartment. If lights, horn, radio... works and no 12V to battery terminal, than check your fusible link in the trunk... If you need to know where the location is for that, just ask. GL

        I pulled the carpet and some covers up yesterday and couldn't find any fusible links.

        where is it?

          The fusible link is the bulge in the smaller cable from the battery positive terminal and is pretty close to the battery.
          The car makes it possible, but the driver makes it happen.

              not sure how this helps but my windows dont stop if I try rolling them up or down while I try to crank. just the click and everything just works fine. shouldnt the k5 or k7 relays get grounded by the starter solenoid and disable acc like the windows? so far lights dont dim, accessories dont stop, and fuel pump doesnt receive a power signal from the main relay.

              should I still be considering ignition switch or bad starter? or can I rule out the switch because the starter is obviously getting power and making the click?

              its getting so cold out which sucks 10x

                yes

                check that the black/green wire is hooked to the right post of the starter.

                  sorry which question were you saying yes to? I'll check for that wire the next time I get some time to work on it, but what should I be looking for in particular?
