I figured out my car has developed unstable voltage flow.
So I replaced oem alternator with 80 amp bosch remanufactured one from pelicanparts. After replacement, I had no more flickering or blinking problem. But after 1 month, it came back
So I got another remanufactured bosch alternator from pelicanparts.
well it seemed it's gone. However, came back after 2 weeks again.
I kinda tortured pelicanparts representatives and I got another one recently. It's been 2 weeks and int/ext lights flicker again and CEL comes on/off intermittently.
I replaced belts, pulleys as well as alternator.
I'm so much frustrated. Any idea would be appreciated.
