In the grand scheme of things, this is nearly insginificant, but it annoys me. My drivers side turn indicators flash at "double speed", similar to how they would flash if a bulb was burnt out, etc. Thing is, ALL the bulbs are fine (replaced, etc). The passenger side is fine. I thought perhaps an open ground, but all the bulbs work fine.
Any tips where I should start? Is the flasher relay kaput?

Don't think the Flasher Relay is the problem as it has a single output that feeds either the left or right turn signals (reference Mr. Bentley). Most likely there is some corrosion (causing high resistance) in one of the driver's side turn signal sockets. Regards, WWR.
Thanks WWR, that's a sound suggestion, I'll check that first.
I'm wondering, too if maybe the relay (or terminals) are corroded, I got some serious water in at the drivers windshield corner shorty before I parked the bunny for 3 years. (I did fix the leak prior to parking)
Matt, there could be possibly some corrosion around relay socket, especially if you have had water leaks. If your car is 1981 or later US-built car, then terminal 49A on the flasher relay is the output for the turn signals and emergency lights.
However, if the passenger turn signals work correctly, then this terminal is probably working OK as this terminal feeds both sides. Although I have not had a flasher relay apart, I suspect that the relay is looking for a ground to start working, either through the turn signals or emergency lights.
The combined resistance of the lamp filaments and the internal circuit of the flasher relay most likely determines the rate of the flashing frequency. If there is some minor corrosion, such as in the socket contacts, in the driver's side turn/emergency circuit, then the frequency of flashing could change and be different than the other side of the car.
I once had a flasher relay that cycled quicker than another relay; however, both sides were the same rate of flashing. The relay is easy enough to replace if you have a spare. Electrical problems are always a challenge! Cheers, WWR.
OK here's a question for WWR...
My flashers don't work at all, but the hazards still work ? The green light on my dash comes on SOLID green when I turn the signals on, but nothing on the outside of the car.
Is it the Relay cause if so I have a new one sitting infront of me just now. All i'd need to know is the location of the Relay on the fuse box...I took a peak at it the other day, and I couldn't see the labels on the Upper Relay's and the lower ones didn't have anything to do with turn signals from what I saw.
Andrew, the turn signals and emergency flashers share the same flasher relay. Since your emergency flashers work, the flasher relay is not faulty.
Have the turn signals ever worked since you had the car? There are three possible faults that may cause the turn signals not to work:
1. Partially loose multiple pin connector to the turn signal switch.
2. Defective Turn Signal Switch
3. Loose or broken wire from Emergency Flasher Switch terminal 49A to Turn Signal Switch terminal 49A.
Do you have a Bentley for your car? If not, you will need to borrow one or get one as additional troubleshooting is described in the Bentley. The above are possible failures, and it is "pot-luck" at this point. Regards and Good Luck, WWR.
My singals worked just fine for me, and then all of a sudden they stopped working on me for some unknown reason. I have the Haynes manual for my car not the Bentley
I checked my fuse box today and made sure that my signal fuse was still fine and it was perfect so I am guessing that it's got to be something much more involved. I pulled the relay as well, and swapped it with the brand new one and nothing either. So I guess at this point my only guess would be the switch. I will try to hunt that down and see if it'll cure the problem....DAMN ELECTRICAL
Andrew, have you changed steering wheel or had the dash out? If so, a wire or connector from the Emergency Flasher Switch to the Turn Signal Switch may have gotten slightly loose.
Otherwise the problem is pointing toward the Turn Signal Switch. However, the presence of a solid green signal indicator indicates that something is happening in the signal switch. This has me puzzled??
According to my Bentley wiring diagram, the electrical flow is from the Flasher Relay through the normally open Emergency Flasher Switch to the Turn Signal Switch. There should be a GREEN/BLACK wire from the Emergency Flasher Switch (Terminal 49A) to the Turn Signal Switch (Terminal 49A). This wire provides the "flashing" pulses once the Flasher Relay finds a ground through the Turn Signal Switch and the respective left or right turn light circuit.
