Electrical problems
I am having the worst month. First is was the highway studdering. Now its electrical. i took off and everything with a backlight started to blink. then the exhaust started to sound crazy and a funny smell out of the a/c. so i turned around. I looked at the codes and nothing out of the ordinary came up. Is it a altinator problem or a computer problem. Also when i turn on the lights the left blinker light on the dash stays semi lite.
thanks for any help

Wow, difficult to tell from that description and there may be some unrelated issues there.
Did you just add or change anything?
If not, start by cleaning up the grounds. Any random gremlins often start there. Check your battery. Make sure its fully charged and the leads are clean and torqued to spec.
Also check the wiring in the rubber gaiters in the door hinges. They can chafe and cause problems.
What I dont understand is why it hasn't thrown some U cods if you have power glitches.
Post the codes so we can take a look

I did just change the Battery and plugs and wires about 2 weeks ago. this morning did clean batter post and i pulled out the left blinker bulb and the harness was a bit black and had corrosion (green and black). i cleaned as much as i could. the flickering of backlights went away. I took out for a drive seems ok.
Thanks for you input and i will keep updated if something happens again.
