Fan Help

[tdaily2]

I have a 89 mtx i have no fan the fan is new and the ccrm works when i put it into test mode.

By "put it into test mode" I assume you grounded pin #14. That would trigger the fan relay thus putting power to the fan. If both the CCRM and fan are good, most likely the signal circuit is malfunctioning. Check the wiring from the CCRM pin #14 to the temperature sending unit for damage. If that all tests good, the sending unit would be the next suspect.
