jerrykiefer Posted January 25, 2015 Share Posted January 25, 2015 I have a 90 reatta. The turn signal going left works perfectly but in the right turn position there is no flashing, the turn indicator just stays on. In checking both the front and rear indicator lamps are on steady. Are there two flasher relays, one for each side or two flasher relays in one can.Thanks for any guidance you can offer! Link to comment Share on other sites More sharing options...
DAVES89 Posted January 25, 2015 Share Posted January 25, 2015 There are two flasher cans. One for directionals [both right and left] and one for the emergency flashers. Link to comment Share on other sites More sharing options...
Guest Corvanti Posted January 25, 2015 Share Posted January 25, 2015 check to see if your emergency flashers work as they should - with all lights flashing that are supposed to. also all brake lights in the rear...a lot of the time, it's a burned "bright" filament in a rear bulb that causes this to happen. or an overlooked bulb upfront. here's a chart of the bulbs: http://reattaowner.com/roj/component/content/article/217-lighting-system/exterior-lights/178-bulb-number-charthope this helps!

jerrykiefer Posted January 26, 2015 Author Share Posted January 26, 2015 Thanks for the quick comeback. \Yes, the four way flasher is working on all corners and no burnout bulbs, front or back. Link to comment Share on other sites More sharing options...
Guest PontiacDude210 Posted January 26, 2015 Share Posted January 26, 2015 I have the same problem with my 90, after I smacked a bulb in the back too hard installing a tail light. Seems to be related to the rear bulbs being connected properly. If you're not getting connection to one of the bright filaments correctly, it seems to do that. Reminiscent of the 80s firebird.

Ronnie Posted January 26, 2015 Share Posted January 26, 2015 (edited) The problem might be the bulb you are using. There are two styles of the 2057 bulbs. The standard 2057 has a gradual taper where the glass comes out of the base as you can see in the photo on the left. Some of the 2057LL (Long Life) bulbs (might vary by brand) have a bulge at the bottom where the glass comes out of the metal base as you can see in the photo on the right.. On my '88 model the 2057LL with the bulge in the glass keeps the base of the blub from seating properly in the bulb socket. I only list the standard 2057 bulb in the Reatta Store for that reason. It might be a problem that is unique to the '88 models or it might just be a random problem that pops up from one harness to the next. I don't know. Bottom line is if you used 2057LL bulbs for the brake lights in the rear you should try the standard 2057 to see if it cures your problem. Also when you plug the bulb in make sure the metal contact in the bottom of the bulb socket has a slight arch to it so it makes good contact with the bulb. Take note of how the pins on the side of the blub keys into the socket. <-- 2057LL Edited January 26, 2015 by Ronnie (see edit history) Link to comment Share on other sites More sharing options...
Barney Eaton Posted January 26, 2015 Share Posted January 26, 2015 From the original post......(1) The turn signal going left works perfectly but in the right turn position there is no flashing (2) the turn indicator just stays on.(3) In checking both the front and rear indicator lamps are on steady. Can we assume he means when the turn signal is in the right turn position, since (1) says the left works.My thinking...... (1) if one side flashes the FLASHER is not the problem since both sides use the same flasher. This pretty much eliminates the relays etc.I think it is a defective Turn Signal Switch or bad connection Link to comment Share on other sites More sharing options...
Seafoam65 Posted January 26, 2015 Share Posted January 26, 2015 If the turn signal switch is lighting up the bulbs front and rear there is nothingwrong with it. All it does is supply power, the flasher makes the bulbs blink. Over the years I'veseen a lot of flashers that would flash one side of the car and not the other due to a slight differencein the loads on each circuit. Try another flasher.

KDirk Posted January 26, 2015 Share Posted January 26, 2015 Also check the ground tabs in each socket on the affected side. Had a 91 Deville years ago in which the ground terminal inside the socket for one of the front turn lamps was broken off and gone entirely. For some reason this caused strange behavior on that side (think it was passenger/right side but doesn't matter) in which the arrow on the IPC stayed on solid except when that sides turn signal was on then it blinked normally. Some kind of sneak circuit as it was 2057 bulb (dual filaments with shared ground) and once I replaced the socket everything worked correctly.I mention this as it is not a problem you would ordinarily be looking for and is tough to spot.KDirk Link to comment Share on other sites More sharing options...
Guest WEB 38 Posted January 26, 2015 Share Posted January 26, 2015 If you can reach the flasher try tapping on it. Bill Link to comment Share on other sites More sharing options...
jerrykiefer Posted January 28, 2015 Author Share Posted January 28, 2015 Thanks everybody for the response.Yes the 4 way flasher works correctly. Could it be the relay under the hood?I will check the bulbs, I would think if I remove the front bulb the rear would start flashing rapidly if the front socket is the problem.\Stay tuned\Thanks again Link to comment Share on other sites More sharing options...
Barney Eaton Posted January 28, 2015 Share Posted January 28, 2015 The front flasher is on a relay that is not associated with the rear...... based on your analysis, that is why I pointed to the switch itself. Link to comment Share on other sites More sharing options...
BEMSTER 3 Posted September 12, 2018 Share Posted September 12, 2018 Having the exact same problem with my '90, signaling left works fine but right will not flash. No bulbs seem to be burnt out. Does anyone know if the OPs issue was resolved? Link to comment Share on other sites More sharing options...
ptt Posted September 15, 2018 Share Posted September 15, 2018 My 1990 Coupe has this turn signal issue too. Could it be caused by the courtesy side marker bulb that comes on when turn signal is activated being burned out??? Link to comment Share on other sites More sharing options...
BEMSTER 3 Posted September 18, 2018 Share Posted September 18, 2018 Turns out I had a bulb burned out in the back that I overlooked. Replaced that, and my issue is resolved. Link to comment Share on other sites More sharing options...
SteveT Posted September 20, 2018 Share Posted September 20, 2018 flasher failure is not uncommon , and typically the right turn signal will be lost first. Not sure why the right side fails first , but with 45 years as a master tech I have seen that happen over and over Link to comment Share on other sites More sharing options...
ptt Posted October 13, 2018 Share Posted October 13, 2018 Location of the Flasher Relay is where??? Link to comment Share on other sites More sharing options...
DAVES89 Posted October 13, 2018 Share Posted October 13, 2018 The flasher cans are located behind the dash between the steering wheel and the console. Link to comment Share on other sites More sharing options...
