Any suggestions as to why a couple of the relays on our 04 Tahoe have heat/scorch marks?
2 of the relays, they are next to each other, have brown heat/scorch marks on them, what would cause that?
Possible shorting, replace these relays and check for shorts with those systems and All grounds including engine block to frame grounds. Figure out which relays these are and check those systems thoroughly. If these relays get replaced and same thing happens again look into a Short finder
