Hello all,

This is my first post on here, I’m currently experiencing a parasitic draw on my truck. I’ve narrowed it down to fuse 12/13 in on passenger compartment fuse panel. “12/7.5A/Climate head module.Smart datalink connector. 13/7.5A/ Cluster. Steering column control module.” Just wondering how I should go about if from here, or if there’s a common problem I should be aware of. I’ve had the truck for about a year with no issues, but had it in the shop a month ago for a new rear end and since then I think I’ve been having this issue. Not sure how or if it’s related.

 

In order to provide a worthwhile reply, we should look at a wiring diagram to see what if anything else shares that circuit. If there is nothing else, the module is suspect.

Could you tell us how it was determined to be that particular fuse .

 

I did a draw test with an amp clamp after I found the suspect fuse and pulled it and the draw dropped down from around 1-2 amps to around .035 amps. Where could I find such a diagram?

 

We have a really good moderator and if he happens to see your request , he just may shoot a copy to us on this site..

 

Hopefully I can get lucky then lol
