Electrical glitch in cluster

[Flybynight]

Driving down the road and all of a sudden all the dash warning lights light up, the speedometer goes back and forth, the tach drops to zero, then within a few seconds it all goes back to normal. It did this about 10 times yesterday and is getting annoying. One time the AC went to full blast on its own???

Has anyone else had this issue? Seems like a short in the cluster itself.

Did the truck stutter at all? Sounds like a dying battery.

Alternators that are crapping out can do some odd things to a cars electronics. I would start by monitoring the charging voltage while driving. Also could try cleaning the battery terminals.

Could almost bet you money its a wheel speed sensor- front right. :madgrin:

Really? It was doing it tonight as well, I can hear a light tick,tick,tick,tick behind the dash and also noticed the passenger side headlight going out when the lights will all light up, then turn back on once they go back to normal. It didn't do this until I put the 17" TRD pro wheels on, which points toward the wheel speed sensor....
