'86 4KCSQ - two quick questions

["Mark W. Byrum, Jr." <markbyrum@erols.com>]

Dear Quattro List:
    I am smelling antifreeze in the passenger compartment now that I am
setting the heating selector over to heat.  No visible leaks yet.
Suggestions as to best places to begin looking??
    Where is the emergency flasher unit located?  Flipping the switch
does nothing and state safety inspection is due next month.
    TIA,
Mark
