Gentlemen:
Starting to get random message of "check rear lights no cruise control"
Checked fuses in trunk found a 5 amp blown, replaced still had message.
However, rear lights are working!
Will shut off car then later start and drive and now no message.
Noticed that the heat was on even though setting was at low (AC not on)
also volume control on steering wheel ont working correctly when you push up volume goes down control on radio works fine.
The above also comes and goes.
Any ideas?

Thanks

 

Probably a bad brake switch. Search the forum, there is quite a bit of info on this.
