So, driving to work, my a/c suddenly stops being cold, and I notice my coolant gauge is now reading completely cold.

I know the temp gauge was working when I left, since I don't drive away until the car's temp gauge starts to move up a bit.

Factory gauge on a 2006 GTO.

The gauge still has power, and all the other gauges work fine, but it's like this gauge isn't getting a reading.

I'm wondering if since it's not getting a reading, if maybe the a/c won't engage the a/c clutch since it can't tell how hot the car is.

Just guessing here, gonna put in a new coolant sensor since it only costs like 15 bucks.

ok fixed. It was the coolant sensor. 17 dollars and 5 minutes of work. Yay for do-it-yourself

Your likely to catch some flak for posting this type of question here...But the short answer us the coolant sensor it's in the passenger side cylinder head. I'd probly get a manual I'd I were you, or have a buddy help.
