OK so that mystery is solved.

I have the right fan relay in it now.. so I guess autozone/orileys are just bringing up the wrong info on my relays.

so Idk what is next.. first off How do I jump it just to make sure my fan motor works correctly? I know I need to do that to see if it works before I fight with more wiring.


by the way I am very very thankful for the help you guys are offering me. I'm sorry If I'm being a pain.. I know NOTHING about electricals and very minimal about mechanical but I'm eager and willing to learn.

lol the previous owner did that. or some cheap shop did it. the switch is still there it just looks like someone snagged it and ripped it out from the firewall area in the cab . I'll look at the plug and also.. I hate to do this since the guy seems a bit strange but this sums up what I need to do and check


right? lol

That's it in a nut shell that guy shows you the average joe way . Which is the best plain and simple .He has a vacuum leak test but instead of a smoke machine he uses a ccigar. I lmao but it works.

I found the plug. in factory location still connected to the rad support. i unplugged and jumped it to the batter so the fan does indeed work.

ok so next on the list is what... coolant sensor thingy,,. guess I need to re watch this vid again lol .. I did the last thing on his list first and apparently didn't work.

I would check all fuses for power in and out first don't think id put batter juice to the plug from it might fry something . Then check for current at relay socket. Check both fuse boxes
