Hi,
Can you help me with the following Turn Indicator issue:
When I turn right (or left), both the rear turn indicators flash. There is no problem with the front indicators. Is this a flasher issue? How to fix this?
Vehicle: 2017 Jeep Cherokee Trailhawk.
Thanks.
So, if I open the rear lights, disconnect the wires, clean them and replace, would this solve the issue?
Scotty normally doesn't revisit questions once he's answered them. As far as a video, I can't recall a video where Scotty did a troubleshooting video on turn signals specifically. If you have a basic understanding of DC current and a multimeter or at least a 12 volt test light, you should be able to find the faulty connection. Check the wiring, sockets etc and look for corrosion, frayed or broken wires. This doesn't require a master mechanic's expertise to resolve.
As Scotty says, be sure to check the tail light grounds. Bad grounds can cause all kinds of crazy electrical glitches.
@chucktobias Thank you, Chuck. But how do I check that?
Physical examination and cleaning as necessary.
So, if I open the rear lights, disconnect the wires, clean them and replace, would this solve the issue? Or, is this a deeper issue that I should go to a professional mechanic?
It's impossible to tell from here. Obtain a circuit diagram for your car and trace the taillights. I had to do something somewhat similar with my Ranger 2 years ago. The battery light came on, I replaced the alternator, and it still would come on. Ford hid a so-called mega fuse between the alternator and the rest of the truck. I only discovered it with the circuit diagram. It was corroded as heck. After I installed the new one, it was fine. The battery light never came on again.
That's not a flasher issue. Generally that is a wiring issue. Something in the back is short and also both go on at the same time. Look and check the ground wiring first. Bad ground wiring will often do that
Thank you Scott!
Appreciate your reply.

By the way, I follow a lot of videos of yours. Perhaps, there is one that matches the issue I am facing. Kindly request you to pass me the link, if this is available.
Have a great day!
