NEED HELP on 88 civic heater motor relay


I have an 88 civic 1.5 hatchback and the blower motor is not working. I think its a relay problem. I have checked the switch and it is functional. I am not getting any current to the fuse for the heater blower motor from the fuse box so i think its a relay. Where would it be and what else should I be checking?


Thanks
Scott
