This is a warning for members who installed the Explorer Auto dim mirror. A whille back I smelled something burning in my truck and could never figure out what it was. Today while doing a tear down, I realized the smell was the relay system I had built. The relays I used were aftermarkets, and I believe they are just junk! The sides of the relays were melting!! I recommend you guys use OEM relays for this mod. If you have a hard time getting them, I can get them for you. Check your relays if you have this mod!
I had these in for over 2 years, but safest bet is to check yours just in case!
