all signs point to main relay

 

just to elaborate a bit, I had the main relay go in my car, and there are 2 schools of thought on what to do with the old one.

1) Replace it with a new part from a dealer or other auto parts supply chain.

2) Re-solder any of the points that have gotten very nasty over the years and either burned through the minimal existing solder and are no longer making adequate contact or have developed cracks and aren't making adequate contact.

There is a really good how-to that I took the liberty of searching out for you.

It can be found here:
