Ya.
You have a cross-circuit between the running light and the turn
signal. If it isn't a whacked bulb (already sagely suggested) check the
lamp bases carefully to make sure one center contact isn't touching the
other. If not, it's a matter of tracing the wiring out to see where
power's leaking. Check, especially, the wires under the front fenders
and in the trunk, as cross-circuiting can happen pretty easily there.
Got that tool box strapped down well???
What's happening is that the turn filament is getting (some) power
somewhere else. THe flasher relies on a pretty specific current to
flash at the magical 2-3 flashes per second rate. If there's a bigger
current draw (like you're pulling a trailer with extra bulbs) it flashes
more rapidly. If it's slower or not at all, there's less current, like
when a bulb's out, or a contact's going bad. Or when a bulb's getting
power somewhere else- like the headlight circuit.
Good luck,
Toby
