Turn Signal Lamps
The TSIG/HAZ fuse in the rear fuse block supplies battery positive voltage to the flasher module. The module is part of the hazard switch assembly. The flasher module has ground at G201. The turn signal lamps may only be activated with the ignition switch in the ON or START position. The IGN-1 fuse in the rear fuse block supplies battery positive voltage to the turn signal switch. When the turn signal switch is placed in either the left or right position, current flows from the turn signal switch assembly to the flasher module. The flasher module then sends an on-off voltage signal to either the left or right turn signals and their instrument cluster (IPC) indicator. When the hazard switch is pressed, the switch contacts are close and the turn signal/hazard flasher module hazard input is grounded. In response to this input, the turn signal/hazard flasher module supplies battery positive voltage in an on and off flashing pattern to all the turn signal lamps. This also activates both turn signal indicators. When a THEFT is occurring, the DIM grounds the turn signal/hazard flasher module hazard input. The left turn signals have ground at G401 and at G402. The right turn signals have ground at G401.
First check your fuses. Then check your flasher relay. Do they light up and not blink? Or do nothing at all? Did all this happen after using the 4 way flashers? Turn your 4 way-hazard lights on and off several times.
Left side of the steering column. Remove the kick panel, the knee panel, and a metal plate covering the steering column
you will find the turn signal flasher relay well hidden, mounted with a clip on the back side of the left non-removable knee panel, behind the lip edge of the panel, hope you have a good flashlight, it is black and can not be seen if you do not know that it is there.

Hi,
I'm Ben and -- hopefully -- I can provide some meaningful assistance. Sorry but the answer is no.
1991/1992 Part #REPB314517 Fits the following 1990-1992 Cadillac Seville submodels:
Turn signal flasher module is behind dash left of steering column near chime module. I have a 94 Seville and I had that same problem you need a Turn Signal Flasher Moduel, I forgot the proper term for it but I had to get mine replaced too. When I hit the signals to turn the side light would come on but the signal light wouldn't. Its a little box you get from Cadillac it only cost like $20 - $25 and you get it installed and trust. It'll work again. I just got mine done this week and my car now has turn signals again.
