Last summer I reported that I was getting a "lower the rollover bars" message on my MFD, but no other symptoms - I can still lower the top when the message is displayed. Now the message is back. It is clearly heat related. It only happens after the car has been baking in the hot sun for a while. I assume these are micro switches? Can somebody with WIS tell me where they are? Near the top or bottom of the assembly? Accessible just by removing the rear seat or do I need to do more major surgery? Any ideas why heat is causing this? Thanks.

The only part I see there is the deployment solenoid, and it's at the bottom of the rollbar assembly. I do not find it as a separately available part. That doesn't mean it isn't, it just means that I can't find it in EPC. But also, there is no mention in WIS of replacing just the solenoid or any switches - it only has instructions for replacement of the entire rollbar. It does not look to hard to remove for inspection. Remove the rear seat (just some bolts) and then a few bolts for the rollbar:
