1993 GTS (early)

Unprovoked, the front and rear left sided directionals have stopped working. Here's what I know:

The right side turn signals (front, rear) flash normally. Fuses 12, 13 are OK. Both left side bulbs (front, rear) are functional. All turn signal lights (left, right, front, rear) work when Warning Light switch is turned on.

When the combo switch (steering wheel) is moved to left turn position, the the pod indicator light flashes much faster than if it is put in right turn position.

It seems that the issue is with part of the combo switch.

Does anyone have any further suggestions?

Thanks for your help!

what lights up when you press the hazard button.?


could be a bad flasher relay...swap in a known good one

I had similar.problem try replacing relay. I think you can use an audi relay as a replacement.

Flasher relay,

if you didnt get the dash notification (faster) with the left, then I would say switch.

Tony: All four turn signal lights work when the Hazard Switch is pressed.

Colin, ChiTown: I hope that somehow it is the flasher relay (cheap fix), but the wiring diagram suggests otherwise. The flasher relay circuit runs into the combo switch 49o --> 49o (BK/WT/GN). That appears to be the place where left and right circuits for the directionals originate. Since my issue is left sided only, and since the Hazard Light circuit works normally (all turn lights flash), I still think the issue is with the switch or the wiring near the switch.

I will try a different flasher relay and report back. Any other suggestions? Thanks.

...park it farther away from the MG?

I used to have one as well.

Flasher relay, I've seen this on an 86.5, and if left on long enough it would start to work.

I know of your pain. The MG has three different kinds of bolts. SAE (fractional) in the rear end which was manufactured by Ford. Whitworth/British Standard all over the body. The engine has metric threaded bolts with Whitworth sized heads. That is not a typo! Only a madman would ever solve a problem that way. It is no wonder the MG car company disappeared.

I've got a flasher relay and a different, functional combination switch being sent just in case. Three of you think the flasher relay is the culprit. We will see. In the meantime, keep the suggestions coming!

I do NOT think its the flasher relay - pretty certain in fact...

The flasher relay only has one flash circuit - the combo switch/(hazzard) switch is what connects it to either(/both) side(s) - so if it flashes OK on one side or with the hazzards - ITS OK.

It must be a bulb, switching or wiring issue

I received a turn signal combo switch to use as a test. Thanks, Roger!

Replacing my switch with the different, used one resolved the problem. And, the original switch now works when it was reinstalled.

So, either I have an intermittent issue with the original switch, or the problem lies with the plug or even the wiring near the plug.

I will leave the original switch in place and see if the problem recurs. If it does, I will replace it.

Thanks to everyone who offered advice. I appreciate it.

Yes, very likely a problem in the wiring. I have same thing with my right turn signals ... flash double speed or not at all, often don't work the first two or three times I try them in the morning, then wake up.

New flasher, different combo switch and changing bulbs side to side haven't fixed ... fortunately, I can just lift up on the lever to signal but would be nice to have it working correctly again.

All,

have been researching things and this thread is pretty similar to my issues. Details are as follows:

Fast blinking turn signal left light only. I have not had a left rear turn signal for sometime. Have been troubleshooting, checked all bulbs and they are good, swapped out right side with left just to make sure, still no left turn signal. I do have right turn signal. All marker lights and tail/brake lights work.

This morning I got in car and same as above, stopped to get gas and when i turned it back on heard a buzzing in the CE Panel, a quick inspection and found the flasher relay was the culprit. Also had no gauges or instrument lights.

When I turn on hazards I get 3 of 4 lights working (still no left rear). When I remove key and flip signal switch either up or down I get all marker and running lights come on along with all tail lights on both sides regardless of which way the switch is moved.

when I turn key to on position, the buzzing goes away when I turn on hazards or signal either way but still get fast blink when moving turn signal switch down for left turn.

I replaced the left rear tail light harness about 2 months ago as three of the 5 bulb holders were corroded. I have checked all bulbs to make sure they are correct type and wattage for the location.

I replaced the combo switch with one I got from Roger hoping that would solve the problem but it did not. I have checked all fuses in #34 through #37 and replaced with new. I checked to make sure they were seated well and DeOxited the locations prior to installing new fuses.

I have checked for voltage in the bulb holder and get no voltage when turning the switch for left signal. I have checked and cleaned grounds above CE Panel as well as under steering wheel.

I am at a loss and could use any suggestions.

UPDATE: Also replaced relay with a VW/Audi part #191953227A

Thanks,

Kevin

if your not getting power to the bulb contact then you may have a damaged or dirty connector at the rear bulkhead ,
you know the drill get some deoxit

A few years ago I had a turn signal light issue that I can't recall in details. To make a long story short, I traced back the issue to be the headlight **** switch that required the contacts to be cleaned. The wiring diagram led me to that.

Mirousse, thanks I will take a look at that tomorrow. Need to get it sorted out as I am planning on driving from Atlanta to Texas for 3rd Coast next Thursday morning.
