Rad. Fan and A/C fan

Having problems with my Rad. fan. and A/C fan. both motors on the fans work…but they dont come on. the car overheats because the RAD. fan doesnt come on…its getting power, and the fuse is good. Is there a relay or something. the only way i get it to work is to hook it up to the battery…want to get it working so i dont have to pop the hood all the time…and dont want to run any wires to a switch…pain in the butt…

any help

thanks in advance
