Hi VehiX and etlsport,

Thanks for those replies! Now the light is on at ALL times, regardless of speed, or bumps, or whether I'm actually IN Winter Mode or not.

No changes have happened recently. The light just came on while driving, flickered for a few hours, and now it's on 24/7.

Winter mode works properly. I can engage it, and then it turns off when I go fast enough, and then I can re-engage it again after stopping. But the light stays on always.

There's no "gunk" around the switches. I will try etlsport's idea of disconnecting the switches to see what happens. If it's a TOD CPU problem, I'll be pissed...

Interesting problem. I never USED the Winter Mode on either of my VXs before, and now I can't get rid of it...
