Eractic signal, stopped working. The panel around switch must be removed; once removed, use fine needle nose pliers to grip the edge of the switch and pull it out. Be sure to grab the plug after disconnecting so it won't f
drop down into the space, hell to get it out. After removing switch, tie cord or wire around switch to hold it until ready to plug in new switch. After plugging switch, push the unit back into place and push it back as far as possible; re[place panel after ensuring part is working..That's how I did it...Most shops wanted to drop the radio unit...I did mine in about 25 minutes. Purchase part online, dealer cost is ridiculous!!!
Turn signals started by periodically shutting down on it's own, and now have stopped working altogether.
Erratic clicking of the turn signal. Intermittent failure with <=> light briefly coming up when it happens.
Blinker sound would stay on after blinker went off and sound off and on. This seemed to get worse the hotter it was outside. Replaced the flasher and can now hear a shorting sound in the flasher. So I guess I will put the old one back and try another new one.
