A short time ago my Dynamic Laser CC started malfunctioning for no apparent reason. I would activate the switch and it would engage for anywhere from 10 to 30 seconds then disengage and flash the C1 error code. I would attempt to activate it again and it would immediately go to C1. I have scrubbed and cleaned and cleaned the two little glass boxes in front of the car, but that doesn't help at all. I've scoured the internet for similar issues, but haven't found anything about it.
Any suggestions short of taking it back to my (awful) dealer who charges $100.00+ just to tell me what's wrong with it?

I have to admit for a 3 year old Toyota "flagship" sedan with 42k miles on it, I'm very disappointed with the integrity of this car. This is one of a few things that has failed since I bought it.
