91 chev cav z24 flasher unit

can someone please tell me where the flasher unit for the turn signal is located. i have found the 4 way hazard flasher unit/OR are they housed together? I own a 91 chev cavalier z24 6 cyl. i hope that is all the info required for a newbie poster. there is a square(what looks like a relay) unit beside the round 4 way hazard unit. thanks for any/all your help!!!
BTW i had to take off both of the coversbelow the driver side dash board to find the 4 way flasher. Is the turn signal close???

There are two flashers...one is on the firewall at the bottom right corner of the driverside footwell. The other one is attached to the frame behind the lower driverside trim panel under the dash, up against the center console. I'll get pics tomorrow if you want.
