Wed evening I dried a couple of coils ouit from another problem I was having and the truck was running fine.
Went out this morning and nothing. Tried to start the truck and just a buzzing underdash area, assumed battery down from something left on. Battery was at 12 volts so put my charger on it. Nothing.
Was sitting in the truck with key in but in off position and noticed the buzzing was still happening. Swapped some relays in the fusebox, nothing.
Cleaned up the battery terminals, pulled the fusebox down and everything looked good. Had had fusebox issues but it seemed fine.

Eventually noticed that the buzzing can happen with the key out of the truck.
Cannot see any wetness under there to cause a problem.

I did do a search and see where roof light leaks can cause a problem by putting water into the wiring and my roof is a little rusty around a couple of the lights.

Any ideas, how do I get to the control box on the cluster that seems to do so much.

 

Update, I had left the ground cable off the battery for 1/2 hour or so.
Hooked it back up, opened the door and could hear the buzzing under the dash.
Unhooked the battery cable and will have to dig further.

 

Update again
Dashcluster is out, when I had it loose and laying on the column I put the ground cable back on. Buzzing was coming from the cluster, stopped when I unhooked the largest connector which is right beside an Omron relayish black box.
No water damage, everything looks perfect and this is the first time this problem has happened.

 

Found the problem



Stupid me checked the connections at the fuse box but did not check for voltage.
Wire was in bad shape aprobably touched it while doing the coils though the truck was working when I left.

Thanks for all the help. LOL

 

WOW. Do you live in a road salt using state?

 

Prince Edward Island, Canada, look it up.
Small island surrounded by ocean and they use a crapload of salt on the roads.

Freeing caliper sliders is a yearly thing or throw the caliper mount away

 

Wow, thought we had it bad in northern Ohio. I do the pins twice a year before and after plowing season. And I still often times end up getting the torch out.

 

Just wanted to say THANKS for posting up that you got this solved. I saw your thread last night and had no clue where to even begin.
