Have to change front left one - no resistanse..right one still good but since half of the car is apart, including windshield washing tank, i might as well change this one as well...so, originals or doorman are 150-250 each. Amazon special - 30 each. Whats the difference? These are really just a wire and a coil around the magnet. Any suggestions?

 

Agreed, they are not high tech. I'd look at someplace like Autozone, Advance Auto, O'Reilly's, etc. One of the parts houses with a lifetime warranty.

 

Have you looked at Rockauto?

 

rockauto has relatively expensive ones, ebay and amazon have both front ones for about $50...vs. $300.i guess i will try that, worse case scenario i will take the bumper off again and replace
