Thanks for choosing just answer.

First you should duplicate the problem.

Drive the car until the signal stopps working
then use a test light to test power from thebatter to the fuse box, to the switch, to the relay, through all connections, and finally to the sockets.

If there is a computer in the circuit you must make sure that the computer is properly grounded, include this as you trace the circuit in order from the battery to the bulbs.

You cant miss if you follow theese instructions. If you need a diagahm and instructions follow this link.

Thnks so much
