C36 temp gauge doesn't work. Cont.

I have a 1995 C36 and I've owned it for almost 2 years. In that time the temp gauge has never worked. It doesn't overheat, the heat works, the fans come on, but the needle will not budge.

I have tried:

- All new sensors

- Bleeding the system

- Different gauge cluster from the junkyard. Ended up taking it apart and using the leads to the temp gauge to test voltage to it. No change with temp.

So at this stage I'm left with wiring or a module of some sort if there is one. Is there a module and does the sensor ground though the sensor a wire?
