[Avalanche]

Hi Folks. Two months after I got my 2nd clutch slave replaced my wife went to drive to work and the car wouldn't start. It acts like the clutch interlock switch is not engaged. I pulled the switch and tested it and it is operational and in adjustment. Any thoughts as to what else may make it behave like this? No hint of trouble prior to this. No codes...that my OBD2 reader found anyway.

Thanks!
Dale
