Most of those people had their cruise light come on and it worked halfway. If yours doesn't do anything, then mosr likely it's a power problem.
\Either you're not getting main power, or one of the sensors is not getting power or you're getting a signal from a sensor telling it not to work or you have a break in the circuit, disconnected plug or broken wire.
here is the wiring diagram for your car, on page 61 is where the cruise diagrams start
If switch doesn't light up, check for power at the fuses, the check for power at the swtich and so on and so on.
