FCA thought it was the switch module but it's not. My Renegade is at the shop now for the "third" repair attempt. If they can't replicate it at the shop then it doesn't count as a repair attempt for lemon law. There are a couple ways to make it act up. Seeing as how it's 72F here in NC I can think of three ways off the top of my head. It only acts up when it is less than 40F (which is why I don't think it is the switch module). So you need to trick the car into thinking it's cold. First, it's still pretty cold up north. I could always take it up to a dealer in Michigan and stay with family for a few days. Second the outside air temperature sensor is somewhere on the front of the car. I plan on pouring a bucket of ice water on the sensor. Third, bottled air, like the kind you can buy at Staples to clean keybords, when flipped upside down shoots out cold liquid. If the ice water doesn't work this is the next attempt. Since after the "fix" my heated steering wheel gets stuck on every time it is less than 40F I have no doubt I can reproduce it at the dealer on comand. However, since yours is more intermittent it will take some effort.
Don't let the dealer tell you this is normal. It is a known issue. FCA customer service told me that engineering had a model acting up at their test center. There is an open Star case.
If FCA doesn't make this right by me without having to file lemon law I am going to take this to the next level. To the heart of thier customer base. Young people hate when technology doesn't work and I will leverage that to the fullest extent.
