The problem is, apparently, with your flash unit.
If you are using standard color slide or print film, it is
balanced for daylight color temperature (~5500K). If your
falsh unit is not properly calibrated for this light temperature
the colors on your prints or slide will be off. If the unit
is putting out light that is too warm, the results will be yellowish
or reddish. If your unit runs cool, like yours seems to be, the results
will be bluish. 

To check out your unit, take it to a camera shop that has a color
temperature meter. They will be able to tell you how far off your unit
is. The problem then may be corrected wither by repairing your flash or
by placing a color correction filter on your flash or over your lens(es).
