fjh 775 Posted August 24, 2019 Share Posted August 24, 2019 swap out the breaker on that circuit if its on a breaker sounds like you were close 1 Quote Link to post Share on other sites
Hyway3 0 Posted August 24, 2019 Author Share Posted August 24, 2019 Afternoon JoeH check all grounds cleaned up still same issue. FJH when u say breaker u mean in the dash board all looked fine in there . When truck has been shut down for a few hours, and you start it up there on but shortly after they go back out .

JoeH 432 Posted August 25, 2019 Share Posted August 25, 2019 Do they come back on when breaker resets? Quote Link to post Share on other sites
Hyway3 0 Posted August 25, 2019 Author Share Posted August 25, 2019 Yes if the truck is shut off for a few hours , when you start it up u have tail lights for a short period of time then they go out again Everything else works as they should turn signals brake lights back up lights just the tail lights are funky.

HeavyGunner 2,379 Posted August 25, 2019 Share Posted August 25, 2019 Like it’s been said above change the breaker. Sounds like it isn’t working correctly.

1965 411 Posted August 25, 2019 Share Posted August 25, 2019 Most of those breakers are the same; swap them around & see if that fixes it. If does that breaker is weak. Mark it with something so you know which is which Quote Link to post Share on other sites

RayRay 0 Posted February 25 Share Posted February 25 I am having the EXACT same problem with rear marker lights on 2014 Pinnacle. They might go on, then flicker a few times, then usually go out. In this condition I put a meter on the feed and it reads about 5 volts. i can’t find the issue. Did you figure a solution to this? Thanks, Ray Quote Link to post Share on other sites
MackTech 8 Posted Thursday at 04:27 AM Share Posted Thursday at 04:27 AM Did you replace the actual terminals in the connector or just the plastic part? The female part of the terminal could be losing connection. It's been too long ago since I worked on wiring to remember what circuit to look at, but if grounds are good, check the terminals.
