Emergency flashers work properly but turn signals not working for both directions. Momentary blip on dash indicator then nothing. No exterior blink at all.
Drivers side led turn / brake light would stop working giving me an dashboard error. Mechanic stated it was turn signal module 600.00 to fix so far
Worked intimittently. Went out during a busy driving day. Halfway through errands started working. Worked for 2 weeks & have now been out for almost a full week now. Researching the problem so I'm not taken to the cleaners by mechanic claiming electrical problems, been down that road & not traveling it again.
