1984 380sl radio, hazard lights, power rear mirror not working.
 

When I tried to turn on the radio all I get is a ticking sound coming from under the dash. Also the hazard lights and the power rear view mirrow on the passenger side does not work. The clock and the interior lights do work so the fuse ( #14 ) must be allright. Could there be a relay that I need to replace? Any help out there would really help.
