I just recently started having a problem with my Trac light going on and off when the pavement is dry and no slick street pavement. It started after I drove in snow while in Chicago this past week and now am in Wash DC where there is no snow or rain yet. Noticed that it seems to happen when the outside temperature gets to around 32-34%?

Can anyone tell me what may be wrong, how the problem can be fixed, and what the repair cost estimate is that I should expect at the dealer??? Thanks for any suggestions, help. Tyndale Cobb
