I replaced the left rear bulb, but the turn signal light it is still blinking very fast. There was some "goo" in the flasher when I removed the old bulb. While I was at it, I checked the front headlight, the turn signal is not working at all. Do I need a new turn signal flasher? Or, it is the wiring?
Fast flashing occurs when one bulb in the circuit has failed. If the back turn signal bulb is flashing, then a front bulb has failed. Try replacing any remaining burned out bulbs (there may be more than one at the front and/or the back - if the right side is ok, check that side of the vehicle for locations reference). Be aware that the problem can also be one or more bad turn light bulb socket connections - in some cases, dielectric grease may have been added inside the sockets to inhibit corrosion. This is not usually a problem, but to be sure, make sure they are clean and free of corrosion.

check your left light fixture.make sure you have a good contact.sometimes they burnout
SOURCE: Left turn signal blinks fast in rear and regular in front
the bulb is blown out. you need to change it. also if the bulb is not blown out or if the blinker still blink fast after you change the bulb then you have a ground problem. just remove that blinker light and check the ground wire on it. if you need to replace it and find a good groun on the car. you should be fine. this is all it is .

any increase in bink speed is direcly related to a bulb being burt out.

no it can not be the flasher. if bulbs and socket is good in left rear u may have no power or ground. need to check wiring to that lamp. also fast blinking is a normal condition when you have a lamp out

No - headlight ok.
The reason that the Right turn signal blinks fast is that there is half the normal load (resistance)
on the right side, since the Right front turn signal isn't working.
Since you replaced the Right front turn signal bulb, your problem lies in the bulb socket or
the wiring to the socket.
(1) try cleaning out the socket - there's probably a contact problem in the socket. You
may need to squeeze the contacts together to provide good contact to the socket contact.
(2) if contacts inside the socket are ok, try back-probing the socket - to make sure that the
socket is getting 12V DC to light the bulb. Replacing a bulb socket is easy, and commonly done.
Any auto parts dtore should be able to sell you a new socket - its just a matter of cutting out the
old one, and then splicing in the new one. Most shops will use small wire nuts, buried under several
wraps of E-tape (electrical tape).
(3) if bulb AND socket ok, you have the worst problem known to man - a wiring fault. In this case,
you'll want to run a new wire from the flasher module (under the dashboard) to the turn signal.
