howdy people - need a little help please.

two days ago, my emergency flasher relay began sticking and making this
horrible buzzing noise when engaged.  no problem, says i.  just get
another relay.  cool.  i'll get on it.  well, yesterday morning my
blower motor (in the front dash) kicked out and last night my wipers
exited stage left.  frankly, i haven't the time to tear the dash apart
during the week and was just curious if anyone hand any quick
suggestions as where to begin looking for electrical shorts.  my fuse
strip is obviously suspect and all seems in working order there.  i
suppose it's possible these things are just about due to go given their
age, but it seems rather untimely that they all go within a 48 hr.
period, no?  fwiw, the only electrical work i've done in the last year
is replace my battery less than a month ago.
