Hello all,
I have a 2007 Vibe. I noticed when trying to hook up a tow wiring harness that my tail/brake lights pulse when the turn signal is on, and the parking/headlights off. However, if I turn on the parking/headlights, the pulsing does not exist. If I remember correctly, this also occurs when the four ways/hazard lights are turned on. I've also noticed the dash lights will also pulse when the parking lights are off, and they are dimmed. Once again, when parking lights are on, no issue.
I am not very inclined when it comes to electrical systems so I'm not too sure where to look or what to look for as an issue. Most common is obviously ground, but I'm not sure what grounds would need to be checked. I did do the DRL/AHL mod, and fog mod (with relay for independent control) several months ago and did not notice these issues. Though no one else has had any issues with these mods (that I've heard of), is it possible this is the cause?
Thanks for your help.
