Standard trailer wiring combines the stoplight and blinker circuits onto the same wire. What you described sounds like you are trying to use 4-way wiring wired to a vehicle with separate blinkers from stoplights.

On your tow vehicle you'll want to install the 4-way harness part # 119250KIT to convert the signal of your tow vehicle that is separate to combined so that you get the circuits to match what your trailer has.
