the turn signals stopped working although the emergency flasher still worked... the flasher relays are all in one unit located in the dash behind the red triangular emergency flasher(both the turn signal relays and the emergency flasher relays are all part of one unit)...ordered a new unit online for about $50.00, takes about 20minutes to replace

Erratic turn signal operation. Gradually got worse to the point that they would rarely work. I removed the hazard switch/relay above the radio. I took the relay unit apart and found there are two relays on the circuit board, the one for the hazards was working fine but relay for the turn signals would turn on and stay stuck on. I sprayed a bit of WD-40 on the movable part of the relay and now the relay/turn signals are working OK again. We'll see how long it lasts.

Flashers stop working after they warm up. Do not flash after a few seconds. On and off working. Ready to replace relay and see.
replaced hazard flasher relay above radio
flashers flash intermitintly
When i hit the turn signal it starts to flash/click and then freezes on. If it the Flasher Relay and is this something i can fix vs going to the dealer
first it would flash fast after a day of that I now get two flashes and it turns off
turn signal portion of flasher stopped working. purchased replacement and installed. didn't take long at all and the part is fairly inexpensive.
