i have a 93 park avenue, the front turn signal lights come on but don't blink, the back turn signal lights do not come on, however the bulbs are not burnt out. Emergency flashers work on front and back.

Front turn signal lights come on but want blink. Rear turn signal lights do not come on. Emergency flashers work front and rear. All lights work come on when park lights or head lights are turned on. Checked for turn signal flasher under the dash, could only locate the emergency flasher.
