My sport mode switch does not work. The button has no light illuminating either mode and the switch does not activate the sport mode (no light on dash or difference in driving mode). I've disconnected it plenty of times with changing out the radio and replacing lights for the a/c but the connection seems solid.
Thanks,

Have you tested the continuity of the switch? I have a spare, with the same lack of illumination, if you find your's is dead.

The switch makes a very noticeable difference in the performance.

 

thanks, I went ahead and ordered a replacement. I'll let you know when it gets here.

 

Yesterday, I took the old one out and sprayed the wire connection with some battery terminal cleaner, reinstalled it, and IT WORKS!!

 

Does the light work, too? Notice any difference at WOT?

 

The dash light works, but the switch light is out. And yes I notice a huge difference at WOT!
