Ok so I have installed my new towing mirrors that has the turn signals, panel light on the bottom and heated mirrors. The turn signals are wired for it but will not come on. I figured it would be a fuse holding it back but no. Any ideas?

The other thing is that the panel light works on the drivers side but not the passenger side and it looks like i have to run a wire to it. My question on this is how do you put the new pin on the existing wire harness?

If all of the features on the mirrors that you bought match the factory options you had, they should plug right in and work.

You could try to plug the old mirror back in to see if everything works, then plug the new one in to see if it's the same.

You may want to check the fuses or also a possible broke wire.

 

Well the original mirrors didn't have the turn signals or any lights for that matter.
