Hey fellows,
Prior to this everything was working.

Yesterday morning(Defogger and stereo on):
No turn signals.

Yesterday afternoon(Just stereo on):
Exterior turn signals - all work (front, back and side)
Interior indicators - right works but not left.

Last night(Headlights and stereo on):
No turn signals (Hazards worked)

Today, I went to see what the matter was and with key on the turn signals worked(not left interior). I then turned on parking lights and t/s slowed way down. So then i started the car and with the T/S or hazards on, I turned on the stereo and blower on, and the idle slowed way down.(barely hold on)

Could this simply be a flasher or the switch, or am in for some wiring time.

P.S. I did have issues with T/S before but tighten down the switch in the column fixed it.

Thanks
