first relay box is located under driver side dash area ,remove under panel then remove 1 screw holding box & box will hang down ,then the relay that is related to rear glass heating is the 1st big relay on the RH outer side of the box there is a small relay before it ,this is a 4 pin relay ,i think it is purple in colour if my memory serves me right ,good luck , also check fuse # 26 & 18 these r the only fuses providing power to relay for rear glass heating ,if relay & fuses r good check heating element ,to check this just apply power & grounds to both glass contacts 1 gnds ,1 power ,& use temp gun to take reading .from cold to hot & if all those r good then u have a bad control unit & DICE unit mounted just above relay box same area.
