Did they ever work, or have you had to have the tires/wheels changed at some point?

If so, then the sensors need to be reset by a tech using the computer console that plugs into your Crossfire connector under the dash on the driver's side. It only takes about 5 minutes to reset the sensors to the on board computer.

It is kind of sad when the delaership employees won't have their car looked at by the techs at that dealership!!!! If he is dirty/greasy/smelly, complain to the service manager!!! Or is he just overworked??
