Fuel Gauge/temp Gauge

[mmcgtk 2]

My fuel gauge and temp gauge isn't working on my 205 d turbo

 

I've replaced the fuel gauge in the tank with a known working one, it didn't work, I tried to connect the terminals in the connector to see if it would move the gauge in the dash(3 pin connector) no luck

 

where could I go from here

same with the temp. gauge

Clean the contacts on the back of the dash, they cause allsorts of problems.

 

Use a glass stick, then wipe over with a minute smear of Vaseline to keep them clean.

Ive the clocks out and in front of me, there is no corrosion on the multi plug connectors or on the clocks, is there a guide on here to dismantle the clocks?
