I'd like to make a circuit that shuts of the vehicle A/C system for about 5 seconds when you start the car moving from a stop.

Both the clutch and brake pedals have switches on them, so any time they are both depressed then the brake is released, I'd like the circuit to trigger a relay that'll interrupt the power to the A/C while the timer runs.

I'm guessing this would require some sort of AND gate, a latch, a 555, some sort power transistor and relay? I just have no idea where to start.

This is really my first grass roots electronics project, so and ideas or help is really appreciated. Thanks!
