Check the ground wire and the light socket for the left turn signal bulbs (front and rear). You might be getting a ground loop.
Usually a rapid turn signal flasher indicates that one of the bulbs is burned out.
The front or rear turn signal flasher bulb may be burned out and needs to be replaced. The turn signal flasher my be defective and should be replaced. The hazzard lights have a flasher unit of their own. These are found up in under the dash in the steering column area.
Burned out bulb Faulty socket and/or wiring/ ground Faulty turn signal flasher Faulty turn signal Switch
When a turn signal is flashing faster, it generally indicates that one of the turnsignal bulbs are burnt out. Either the front or rear on the same side. Replacing the burnt out bulb should correct the issue. If both sides are flashing either too fast or two slow, then the flasher module is defective. (Or multiple bulbs are burned out, read above) The flasher can be replaced with a new one that should cost under $5-10 and is available at any auto parts store.
Many mistake the hazzard flasher for the turn signal flasher. Maybe you replaced the hazzard flasher? Also, a burned out bulb will not give enough electrical resistance to the circuit, and result in a very slow or stopped flash. Since your flasher is most likely mechanical, turn on your hazzards and put your fingers over the flasher unit. If you feel it click on & off, then you need to find the turn signal flasher.. because you are touching the hazzard flasher.

Probably burned out bulb in rear one. AJ
Legally a defective catalytic converter must be replaced.
Incorrect flasher relay installed.
If I understand the question, you probably need to replace the flasher. First make sure that all of the lights are working since having burned out bulbs will not supply enough load to make the flasher work.
Check / replace the flaher relay I have never heard of a flasher relay---If one side flashes but not the other it is not the flasher (one flasher is used for both sides) most likelya bulb is burned out
Goodman CK30-1B : Just had the same problem. dual run capacitor burned out, whcih was caused by fan motor overheating (bearings worn out) or vice versa, which burned out yet another capacitor, until I replaced the fan motor.
