   I have been having some problems with the dashboard, temp rev and fuel gauges stop working only speedo work.
   
   
   I switched to a similar dashboard and the rev dont work and the hand brake light is always on.
   the fuel gauge it seems to be working well but bouncing a little bit.
   
   
   I do not know what else to do,
   if someone can help me I would appreciate it

   I have had the exact same problem. Only, in the reverse order.
   
   Rev counter doesn't work + handbrake light on.
   Then
   Rev counter doesn't work + handbrake light on + fuel gauge not working + temp gauge not working.
   
   Fuel+temp fixed by new clocks.
   
   The rev counter and handbrake light are still on.
   The handbrake light is also a general warning that something isn't right.
   
   Your fuel gauge, try earth the sender closer to the tank.

   update
   I've tried everything and I still couldn't find the problem.
   I noticed now the warning sound no longer working when I open the door with the headlights on, if I remove the F1 fuse the warning sound work

   You have a 1.5D, these don't work the rev counter the same way as a petrol model.
   
   However, you've narrowed it down to a problem with the circuit on Fuse 1.
   
   Fuse 1 is for the coolant control unit, tachometer, and the glow plug relay and warning lights.
   
   It sounds to me like you have a broken wire/earth in the dashboard wiring loom and it is back feeding down Circuit F1.
   
   Have you checked the dashboard earth at the base of the A pillar on the drivers side?
   
   Also, is there anything else that isn't working? Do the side lights work as normal? Do you have power at the cigar lighter socket?

   yes i already checked the earth points on both sides. but I haven't test yet if the wire is broken.
   
   tomorrow I will take out the dashboard end test the earth, if the earth is good I will remove wire by wire from the dashboard connector and I hope to find out which wire is causing this problem.
   
   but everything else is working well
