Whrrrrrr Whrrrrrr whrrrrrrr vroom

The Lovely Harvey's Equinox, The Mighty Nox, consumed a battery.

Florida is hard on batteries and this one had come with the car when we bought it used.

Three year old Autocraft.  That's about average for our weather, unfortunately.

GM...

Oh, GM...

First!  Remove plastic cover over the PCM.

Second!  Remove screw holding PCM to the battery tie-down.

Third!  Slide PCM off battery tie-down and discard fold over out of the way.

Fourth!  Grab the 9mm deepwell socket thinking it's a 10mm and try to unbolt the visible nut for the tie-down.  Too small.  Grab the 11mm, thinking "nothing is 11mm on a GM".  Too big.  Check inch sizes.  Nope.  Use crescent wrench.

Fifth!  Discover strap is still bolted to something and undo the push-me-pull-you pins to fold decorative plastic cover out of the way.  Find the offending screw, discover it's the same size as the nut and use the crescent wrench again.

Sixth!  Disconnect battery and discard.

Seventh!  Install and connect new battery.

Eighth!  Discover your mistake with the 10mm socket and use correct sized tools to reinstall the tie-down strap.

Ninth!  Resecure decorative cover.

Tenth!  Slide PCM back in place on tie-down and secure with screw.

Eleventh!  Slide PCM cover back over PCM!

Twelfth!  Take dead battery back to parts store to recover core charge.

Thirteenth!  Baffle the staff that it took you their quoted "30 minutes" to change out the battery including travel time.

DONE!
