Seeing as there aren't any threads for Demonic Possesions I'll put this in here.

Last night I was sitting in the truck with a friend chatting about vehicles etc after a coffee. I had just finished telling him that the blazer has been pretty good to me & it's only going to get better with the mods I have planned when there's a click of a relay & all the interior lights come on & then click they all go back off! D'OH!!!
We both stop talking, slowly look at each other with a wtf look on our faces & start to laugh.

What the hell was going on? (other than the lights) Niether him or I opened a door or touched anything.
It was idling for about 5 mins, normal engine temp, revs about 600rpm, volts around 14 etc... everything normal.
It was running fine before & since then. I even looked to see is there was another GM around & someone was walking towards or away from their vehicle & clicked their key fob. lol

 

Welcome to the world of owning a blazer

 

The Blazer's know when you talk about them...

 

It was saying "I love you too"

 

Just try not to make it mad, else more important things may act up.

But seriously, fleeting electrical problems almost never get solved. Check your grounds and good luck.

 

Yea I would check your grounds for the interior lights and the relay. Something gave power to the relay too. Get a wiring diagram and trace the power back. See if there are any obvious problems.
