2003 malibu elec problems with DRL & turn signals	Sign In

Hi
the turn signals on my 2003 Chevy malibu only work correctly when it's daylight and headlights are off.

When the
headlights are on and I turn my turn signals on, all 4 flashers come on, albeit one side
dimmer than the other. My daylight running lights are not working. Probably why they
work in the day light. here's what I have done with no success. Changed the Multi
function switch, changed the 4 way flasher unit, replaced all bulbs, replaced both rear
light circuit boards. Checked all fuses, checked the relays and also the Resistor. Hope this makes sense. Any help would be greatly appreciated. Thank you.

I would probably look for a bad body ground for those circuits.

WOW!!!! That was quick, thanks.

Yes I will try that next. Just on my way out to buy a Test Light.

I forgot to also mention that I have no horn (works with wires directly from the Battery) and the cruise control only works intermittently.
Not trying to sneak in a new post here just wondering if they are connected somewhere in the circuit.
Thanks again HT.

A single bad ground connection can effect many different things. Look around the radiator support for the ground wire.
