2020 Silverado 2500HD turn signal hyperflashing


Recommended Posts

Replaced original LED factory tail light assembly with another factory LED tail light assembly. Had water in lense from a cracked lense, hyperflashing

After replacing the assembly, still hyper flashing 

 

What now,?  should I disconnect batts and try to reset ?

 

Please advise 

 

Thanks

Before disconnecting the batts, let's try a quick fix. Have you checked the flasher relay or load resistor compatibility with the new LED assembly? Sometimes, the system doesn't recognize the lower power draw of LEDs and starts hyperflashing. If that doesn't work out, a battery disconnect might do the trick to reset the system, but it's probably a good idea to check out the relay/resistor situation first.
