INSTRUMENT PANEL DOES NOT WORK CARAVAN 96 3.0

Hello,
if the instruments of the caravan 96 Motor 3.0 could help me no more marks the gasoline but the velocimetro and the temperature of the refrigerant no, the temperature and speed sensor changed and I did not work check the fuse of the markers and it is fine check false contacts and it is fine changed the board and I did not work if they had the electrical diagram of the board of the board
.

Your problem is probably in the configuration of your computer, it happened to me in a Plymount Freeze (where stratus) presisted from 96, after we changed the computer, no indicator of the board worked, led it to check it and if they configured the computer (I do not have the most minimal idea of ​​how they did) but Jalo !!
