Troubleshooting No Turn Signals with T-Connector Wiring Installed on a 2023 Hyundai Santa Fe

Updated 02/20/2023 | Published 02/19/2023

Question:

Have 2023 Santa Fe. Installed CU94FR a few months and went to use for 1st time to rent a U-Haul and neither of the blinkers worked on U-haul. Brake lights did work. When I got home put a test light to connector and had no power coming on for blinker either side. Any thoughts?

To test the T-Connector Vehicle Wiring Harness # CU94FR on your 2023 Hyundai Santa Fe you can test at the 4-Way connector, but it would also be a good idea to test the wiring coming out of the converter box as well as the green and yellow wires you see on the connector that goes to your vehicle.

If you see power on the green and yellow wires but it isn't coming out of the box then you know the box is bad and you'll want to take advantage of the limited lifetime warranty of this wiring. If you don't see power on those wires prior to the box then you'll want to take a closer look at your vehicle side of the wiring.

Let me know if you have any other questions!
