Re: 2005 Grand hard start and random shut off while driving

If the harness is discoloured, melted, some wires are harder than the others, or show some other weird sign of heat (a bad contact cause heat due to increased resistance), or is loose, then it might be it. Also, look at the pin color... Blueish/black is a sign of heat.

As to why now and not before, contacts are a bit complex... I mean, the metal have to touch enought, if the contact do not it heat up can burn some oxide or melt some metal, or disform the shape of the contact, causing a new contact area... also, an electric arc can spot, pierce throught the oxide layer, melt and alike the contacts...

And yes, it does go behind the ignition key... and can be a pita to get to. On my car I had to remove the plastic around the steering, then the bezel around the instrument cluster, remove the instrument cluster, remove the kick panel under the cluster (the panel on top of the pedals), the central consol bezel and finally the radio... All that for 3 bolts, 1 pin and 2 connectors...

But the issue I have is gone now, yay!
