Yup .................. I'd be more inclined to believe that they're resistors for the radiator fans. And judging by their location ( under the front bumper ) that would seem right.
But I'm sure that somebody with more knowledge will be along mighty soon to confirm!
Thank you..... It appears to be the ac blower resistor.... Though the ac and blower all work fine, so......I'm not sure yet. The bumper may have been replaced at some point so I'll be checking to see if it's wired anywhere.
