Why 2 micro switches in Console ?
I believe there are TWO micro switches inside the console of an automatic shift C6 (Yr 2009). It’s my understanding that one is to let the computer know the shifter is in PARK to give the OK for the starter motor to crank. Can anybody explain why there are TWO micro switches and what each one does? I’m having an intermittent crank problem and I’m trying to trace down possible failure areas.

On the A6 shifter, one is to let the computer know that the shifter is in park, and the other to to power up the park release pawl once the car is starter with shifter in park, to engage the solenoid to pull the pawl out of the way until you shift out of park, and once out of park position, remove the power from the solenoid so it does not burn up by being energized all the time when driving and shifter out of park isntead.
On the A4 shifter assembly, you just just have the pawl solenoid contact switch in the assembly, with the park switch down at the output shaft on the trans isntead.

If you are not getting this alarm when it fail to crank, then look around the starter connections as a starting point.
Good Luck

The micro switches in the console for the shifter is explained correctly. If the Park position switch was the culprit, you should be getting "Shift to Park" alarm on the DIC.
If you are not getting this alarm when it fail to crank, then look around the starter connections as a starting point.
Good Luck

Car starts & stops fine so far ---- but this has been an intermittent problem so I need to see if it resurfaces. The other likely culprit could be the brake sensor switch. Corvette with it's cheap Chinese electrical parts and cheap plastic parts everywhere makes for never ending headaches.
I love my Corvettes but I really hate getting stranded. In the past year I've had the STUCK IN PARK problem; the SHIFTER CABLE disconnecting from the shifter leaving me stranded and now the intermittent no crank problem ---- and the car has less than 12,000 miles.
I'm 79 years old and I just want to enjoy my cars.
Thanks for your help
