Electric Steering Fuse?

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?

 

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

I'd also double check your tire pressure.

 

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.

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.

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!!!

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
