i had same problem with my 94 laguna,
the drain off hoses lead from each front corners of sunroof, down inside front door pillers, leading down
to underneat the wings inside front wheel arches,
that is where the problem starts, the outflow/drainoff
hoses get blocked by mud twiges leaves etc...
as yr lookin at drivers front wheel, unscrew the wheel arch from bottom left workin upwards and
appox 6" to 9" up from ground level you will see a plastic type cap this is the cover for the drain off hose
lift this off but be carefull as when you do this the lodged water will flow out like a river just to make sure the hose is totally clear use a stick/wirehanger to help free any leaves/mud etc lodged in hose, repeat the same on passenger side arch.... hopefully this will solve your problem...
