Saddletramp Posted February 24, 2007 Report Share Posted February 24, 2007 I have a 92 StS which the turn signals do not work. The emergency flashers work, all fuses are good (the ones that I can find) When you turn the signal switch to indicate turn, lights do not light Chilton manual I have indicates a relay in trunk area left side, which of the ten relays is the directional relay, could the relay keep the lights from coming on,and not flashing,OR is it the switch in the colum Link to comment Share on other sites More sharing options...
BodybyFisher Posted February 25, 2007 Report Share Posted February 25, 2007 This is a difficult question to help with. It can be so many things, a bad ground, bad switch, bad flasher. I did not know there was a turn signal relay but if you say so. I dont have a factory service manual for the 92 but that is what you need. You need to do some testing based on a diagnosis tree from the manual.. Maybe someone will post the turn signal diagnostic tree for you to look over..

adallak Posted February 25, 2007 Report Share Posted February 25, 2007 It's rather the switch itself than a relay. Mine was bad a few years ago (intermittently) then got fixed on its own. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...
MAC Posted February 25, 2007 Report Share Posted February 25, 2007 Is there a separate flasher for turn signals and emergency flasher? If so, I would check the flasher. Are you saying the flasher is clicking but the directional lamps don't light/blink? If both left and right outside lamps are not working I would tend to believe the problem is something other than the turn signal switch assembly. Are you sure the fuse is good. I would replace the fuse with a new one just to make sure. Link to comment Share on other sites More sharing options...
Saddletramp Posted February 25, 2007 Author Report Share Posted February 25, 2007 Thanks for your replies, The flashers will flash and the outside lights will flash, if you try the signals you get no flash and no lights outside or inside. I have used a Ohm meter on every fuse in the car I could find, all check ok. I pulled the flasher from under the steering colum, Ohm meter indicates ok Ohm meter to flasher plug indicates good to ground on hot side and nothing on ground side with key off. Chilton manual I have indicates ,in the schematic section, that there is a directional relay in the trunk area, I pulled down the panel behind the seat and sure enough there are 10 relays. With no indication as to the correct one. Initially, The signals quit working, I pulled the maxi fuses and checked these and placed same fuses back in, the signals worked, till last friday. They just quit again, tried same thing with fuses to no avail. This is leading me to believe a relay has gone bad. Initially it was stuck, pulled the fuse and no power to it released it and now it has finally given up. I am actually hoping it is NOT the turn signal switch. Any further help is greatly appreciated.

Cadillac Jim Posted February 25, 2007 Report Share Posted February 25, 2007 There is definitely a separate turn signal flasher (three terminals, square, black, mounted very high above the left of the steering column behind the speedometer) and hazard warning flasher (two terminals, round, silver aluminum, mounted beside the headlight switch). Your symptoms sound like the turn signal flasher to me. You can't check it with an ohmmeter because it's electronic. The hazard warning flasher is conventional and can be checked with an ohmmeter, and that's probably the one you checked. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

According to chilton manual, and I'm not doubting your word," 1990-91 Eldo and Seville are equipped with a seperate signal and hazard module behind the instrument panel. Mine is a 92 Seville is why I did not look for a seperate one but I will now. Link to comment Share on other sites More sharing options...
Saddletramp Posted February 25, 2007 Author Report Share Posted February 25, 2007 Thank you for all the replies, I got back under thedash and looked around better under where the hood pull is located toward the steering colum lay a black box, unhooking it was fun, becuase you cannot see it except through a very small opening in the frame and cover panel. Got it out to where I could get to it and turned on the key for some reason and it went to working turned plug over and pushed connectors in tighter and seems to have resolved problem. In other words, somehow or another it had worked itself loose. Thanks again for all the replies Link to comment Share on other sites More sharing options...
