Turn signal problem

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
