The 4 way hazard lights, as well as the directional, work for a few minutes and then stop on my 2004 Nissan Frontier. Do I need to replace the 4 way flasher switch? Can you tell me where it is located? Is the preference for dealer parts over secondary market? Thank you.

try the turn signal relay first:) it will save you some $$$ if its just that and if it isnt just return the part for a refund

moved to frontier.
