Issues with turn signals

[Steve R]

New here, was recommended by manager and Auto Zone. 2006 Z71 Tahoe LR turn signal illuminated when power turned on. All other signals work fine along with Hazard lights but LR constantly glows and indicator on dash stays on. Removed bulb and drove for the night, next day operates normal with no issues. Background, summer of this year the LR signal burned out I replaced both rear bulbs with LED. Naturally the signal blinked quicker and never bothered with any sort of voltage reducer. Housing and wiring are good with no corrosion. Any ideas would be appreciated. Before this happend bout after replacing rear bulbs I noticed the L mirror in glass signal not working. I do not believe that the two are connected. Thank you for any advise or others having similar issues.

Welcome to the forum! Did you try swapping incandescent bulbs back into the turn signals? If the incandescents worked, add the LED resistor packs to the turn signals and see if that helps. You may also want to swap out the flasher if you still have issues.

^^^ These would also be my suggestions.

In addition check to be sure the 7-pin trailer wiring connector is clean and no dirt is in it. There is a junction block above and behind the RR tire that the rear lighting goes through. Make sure those connections are clean.

You can find wiring diagrams at www.charm.li.

Definitely check the rear lighting block for corrosion. It is by the rear left wheel. You can clean any green pins or choose to replace it. It’s cheap.
