I have a 04 4Runner V8. When I put my driver side blinker on- the front works correctly but it casues the rear reverse lights to blink. There is also a clicking noise coming from under the truck sounds like aroun the transmission. Any ideas? I have not had much time to search and just joined the site. Any help would be appreciated!

 

Do you have a trailer wiring kit in there? They can cause weird problems when they go bad.

 

It does have the factory trailer kit. Guess I could check that out to see if there are any shorts, etc. Thanks. I still haven't had time to do much research or trouble shoot. I was hoping whatever is clicking near the transmission was a bad sensor or something....
