the turn signal would word for a couple of days then stop working.I downloaded a diagram of the fuse box from wjjeeps.com/fuses and it showes that fuse #20 is 10amp and on that circuit is ignition run, ac/ heater control/ left and right turn signal switch sense and heated seats. I do not have heated seats the fuse for the heat also blew I removed the fuse for the ac/ heat and now the turn signal worked for 2 day then stopped. the next morning they worked for 2 more days. now instead of clicking I head a buzzing sound from the flasher relay now they are not working. they might work in the morning. my question is , what is the left and right signal sense? and if I removed the fues why did the flashes continue to work. is there another circuit they are on or do I need to replace the flasher again. it was replaced about 2 years ago.

Hi vncntsbr,

Thank you for the donation.

The right and left signal sense are from the multifunction switch indicating either a left or right turn when the circuit is grounded.

Symptoms indicate the flasher is most likely faulty again and needs to be replaced.
