Just purchased a '98 SUS and replaced engine. Running well but there is a rythmic clicking from under dash and fans operate when ignition is on. 

Saw this once on a '95 Legacy when an under dash diagnostic connector was plugged in by new owner thinking that every connector should be connected.

Unplugging it brought operation back to normal.

On this '98, however, I have been unable to find any connected yet that should not be, as in the green connectors near the center console side.

Any suggestions appreciated.



Update: No check engine light.

              But found two corroded fuses in main panel and one blown fuse in under hood panel

              Once replaced, all is well. Thanks!

keep looking for the green connectors.

until you find them un-plugged, assume that is the problem.


there may also be a pair of ''black'' diagnostic connectors under there also.

but i have not heard of them causing problems.

but they should not be connected either.


do you have a ''check engine'' light?
