Hi, the analogue clock has stopped working in my van, temp gauge been dodgy for a while, fuel gauge works as normal, fuse number 3 is ok, rest of dash appears to be functioning normally.
Any ideas what to check next? Tried resetting to see if it was seized but no joy.

Start by looking at the 14pin connector under the dash where it connects to the dash circuitry. It can all get corroded / worn there and cause issues.

If that is OK, it's multimeter time.
What are actually the symptoms with the temp gauge? ( Does it show constant high temp, or no temp etc...? )

The plug looks fine, clean and corrosion free, temp gauge doesn't move at all, was reading between normal and low for a while but now not giving a reading,

Check your 10v voltage regulator.

Would that not affect the fuel gauge as well? That's behaving normally.

If it's OK, check the capacitors in the clock next - they are well known for failing after 30 years or so. Posts on how to somewhere around. Maybe even in the Wiki.

It would.
Forget about it, the clock doesn't use the voltage regulator it is a direct 12V feed, just check you have 12V across the two screw terminals onto the PCB at the back of the clock, if you have then it is a fault with the clock.

As Big Herb says - if the plug looks ok, then it's multimeter time.
