why does my car hate me?

[DNRC]

I've already put a couple grand into the thing fixing it up and today the blower motors on the a/c give up and now nothing comes out of the vents even if I turn the a/c off and put the heat on, nothing. A couple days ago when I turned on the defroster it kicked on as usual but when I turned it off it kept going until I hit the a/c button. A few days before that my check engine came on and took it to autozone and they said it was code 420 which is either a bad oxygen sensor or bad cats. When it turned cold here my bushings in the front started to squeak when I turn. Also when it gets to 37 degrees outside my car beeps at me and the temp display comes on with the F flashing. meh, I'm kind of beyond annoyed with my car now.

I can't speak for anything but the last item you mentioned ... the computer in our car tells us when the temperature lowers to 37 degrees (to prepare for freezing roads) or when the temperature raises to 38 degrees (to prepare for ice thawing). This is normal.

The rest ... good luck, my man. We all have this "love/hate" thing going with our cars.
