I also have a 2007 LTZ and I am experiancing the same issues. Wet or dry weather, siting in a parking lot or my driveway, the wipers automaticlly start and the wiper fluid with dispense. Even playing with the variable speed switch does not stop the wipers. Any suggestions or guesses as to the problem?
This may be due to a leak at the o-ring connector. The wiper heater module may need to be replaced. This is just a suggestion and is not meant as a diagnosis.
I recommend consulting with a certified techncian for an official diagnosis. They will be able to provide more information after inspecting the vehicle.
If you have additional questions, please feel free to contact me privately.
