Default Turn signal problem

Left t/s works front and rear. Right turn signal the flasher goes real fast,
and the right front doesn't flash, but the rear taillight light does.
Strange because all the bulbs are good,(new bulbs), and i know that a rapid
flash usually means a bad bulb. The 4 ways only work on the left side and
right rear. This is on a 97 Neon. The wiring looks ok, no bare wires
anywhere. Could it be that both flashers are bad? Anyone ever run into this?
Any help appreciated.

Bad bulb or socket. Swap the right/left front bulbs. If the bulb woks
then it's a bad socket/wiring fault.
Just because it's a "new" bulb doesn't mean it cannot be bad. Only takes
a drop to the floor in the package to break the filament.

Mechanical TS flashers use current to heat a bi-metal strip.
The more the current, the faster the flash.
There is a short somewhere, not an open.

Also check the ground wire from socket to frame. Could be corroded at
frame end.

No, the wiring to the right front is bad, or the socket is bad. Consequently
it's doing the same thing that it would be doing if the bulb were bad.

May not be a mechanical flasher. Most likely on a car that new it is
electronic, in which case it will flash that side at double speed to
indicate a bulb out, rather than not flashing at all like an old
mechanical flasher. I'd concentrate on the RF corner and find out
what the fault is there. Does the parking light work on that side?
Probe socket for both parking and turn signal functions. Try manually
grounding the socket (assuming it still uses a regular 1157 type bulb
rather than one of those wedge base things) and see if that helps. If
it does trace the harness back to chassis ground and clean/repair
connection. If you have voltage at both park and turn terminals and
resistance from socket to chassis ground is <1 ohm then try another
bulb or look for a bent/corroded connection in socket

good luck

Default Turn signal problem

You've received numerous responses pointing to bad ground associated
with the offending right front... And that does strike as most
likely-culprit... Please, however, put parking-lights on and observe the
turn signal behavior. I suspect, if bad ground is the problem, the lamp
will flash, but not quite "look-right" (due to a sneak-path to
ground)... If this does not occur, the most likely, in no particular
order, are bad-out-of-the-box bulb, or bad wiring farther from the socket.
