WTF is this!!! help!

Alright, not sure what the hell happened but all of a sudden my truck started doing this (watch video). I havent done anything lately and my alarm that was installed never really worked quite right so I was going to have that redone here soon so I tore all of that out and its still happening. This goes away when I open the door and doesnt do this if I turn the truck off with the door open. Please help lol

When was the last time you replaced the batteries?

Ya. Low batteries or bad connections of the batteries has been known to cause seizures.
Get them tested and buy some new acid and lead if you need to.

They are fine but I can't really keep the doors open for long or have the radio on for long before they are dead. The volts are around 11.5 for a minute or so after starting it but they charge up...

Perhaps try replacing them and see if the problem goes away. I only say this because I've seen similar things happen when batteries are low.

If you're reading the Volts off the CTS, that's an "okay" indicator. But you need to get them flow tested by a real battery tester.
(I call it flow tested... dunno what the technical term is).
And 11.5 is lowish. But not terribly low. Mine run around 14v and when I start it they dip to 13.4v for less than 5seconds.
But then again, mine are a few months old.

lol.
Better to do batteries now because low volts starts to fry the FICM.
Studs aren't as necessary compared to good volts.

A test at vatozone or oreillys is free.
