My Turnsignals and hazards suddenly stopped operating. I replaced fuses even though they looked fine. Has anyone heard of this. Could it be alternaor? I am also currently suffering an engine power loss that started before the signals stopped working. My engine service light also came on.My dad has a GM product and he started having engine powerloss right before his alternator went out.

 

possibly maybe bad battery

 

I gave up and took it to the garage. Turns out I needed a new control module. $350 but its fixed.
