Electric Steering Fuse?

hotrodz37 · September 11, 2015

Hi All,

Beginning last week my steering started acting up. Every time I get in the truck it drives differently. The wheel used to be effortless to turn, now I have to put some muscle into it. It was somewhat like this in winter but here in FL its 100 deg right now so that't not the culprit. No dash warnings or anything.

Does anybody know the fuse for the Electric Steering? I have looked at all of the fuse blocks and nothing is labeled Electric Steering. I want to pull mine to reset but not disconnect the battery. I had read that the Electric Steering is run off of the AC motor so I'm thinking it might be fuse 56 or 57 but would love some insight.

Here is the 2014 Sierra Manual:

https://www.gmc.com/content/dam/GMC/global/master/nscwebsite/en/home/Owners/Manuals/01_Images/2014-sierra-1500-owners-manual.pdf

Fuses listed starting on page 10-44.

Any help would be greatly appreciated!

Maybe when the ac is running the power steering doesn't get as much power?

I'd also double check your tire pressure.

Plausible for sure, but I have had the ac on blast the last 5 months here and it started just this past Monday.

I thought that might be it, so I bumped it up and still having the same issue.

I did notice this morning after I lowered my tire pressure that the steering felt stiffer. Raised it back up and it was easier to turn.

175 amp fuse at the battery fuse block. No warning messages, lights? If not then fuse must be good.

subcribed (is there a way to do this that doesn't involve posting a message?)

Tbarn, how do I change the 175A fuse. It looks like all the fuses in the battery fuse block are connected. I don't have any power steering. I do have a service warning. The front end of my truck was under water up to the top of my tires for an hour. My EPS motor was obviously submerged. I did "throw" water up to the hood while spinning my tires. Any ideas would be greatly appreciated.

175 amp fuse. That's a big fuse. Does that include the starter or just everything else?

It's a 60 amp EPS fuse under the hood

I have similar problem with my 2014 Silverado. I changed out the battery but then I was tightening the cable on the neg post and let my wrench touch one of the posts on that bettey junction box that sits on top of the battery. There was a spark (duh). Then when I started the truck, there was a message and I had no power steering. I assume I blew a fuse, but can't find one the says power steering or anything like it.. At least not in any of the three fuse boxes I found in the manual.

While changing the battery in 2016 Tahoe, my wrench slipped and shorted the battery negative terminal to the 175 amp terminal on the battery block. I tested continuity with 12 volt light probe and there is continuity on all terminals EXCEPT the one I shorted out. Is there a way to fix this or do I need to buy a new battery block? The dash warning says power steering needs service, and it's true, there is no power steering. If I replace the battery block and reconnect it, is there anything else that could have been damaged by the shorted circuit?

Also, there is no fuse listed in the owner's manual for power steering or EPS. I checked all the 60 amp fuses and they are fine.

Thanks!

Yes, you can do it without replacing the block.

Buy a Mega fuse holder. ( https://amzn.to/2SEymdg )

Buy a 175amp Mega Fuse ( https://amzn.to/2Ss33U9 )

Wire it in and done.

Wow, I had no idea those existed. That definitely would work. I ended up replacing the fuse block, hooked it all up and power steering is back! I haven't noticed anything NOT working so far.

Thanks!!!
