I'm experiencing the same issues and i think the problem might be a faulty relay.
From past experiences, you usually start in a backwards manor which also is from cheapest to more expensive.
Fuse - relay - wiring harnesses (use multimeter to look for voltage) and then up to the real hardware.
The ticking you hear is the relay clicking on and off. Now if i only knew where the relay was or how to access it.. that might solve the issue?
Good luck gents!
