Compass/temp mirror on '07 Classic

Just scored a compass/temp mirror off of eBay. It came from an '02 Silverado. I had purchased an ambient temp sensor in anticipation of needing it for the mirror. My truck already had one on the core support! Go figure.

 

The eBay mirror went right on and plugged in with no issues once I calibrated the compass. I missed the temp. and auto-dim more than anything else from my '04 Silverado.

 

So, now I have an ambient temp sensor that I can't use... eBay, here I come :banghead:

I didn't find out until AFTER I bought my 99 Yukon a couple months ago that it has electrochromatic OUTSIDE rearview mirrors. I knew it had hte center rearview, but I've never seen auto-dim SIDE mirrors before. I LOVE them, and if I can find an aftermarket set for my Camry, it's getting a set too.

Hey are you all saying that you have auto dim outside MIRRORS? On my Yukon, I have Auto dim on the drivers side, but the passenger side is normal glass. Can I get a passenger side Auto Dim?

I'm pretty sure the passenger side is electrochromatic also. I could be wrong, but I'll check it out later and let you know. I'm CERTAIN though that the driver side is.

 

Although now that I think about it. Why would they put electrochromatic on one side and not the other? It doesn't completely make sence. Maybe it's not getting the power it needs.

I wonder if my '07 Silverado Classic is also wired for the temp sensor? Mine is the W/T trim. I just purchased the mirror off of ebay.

Your W/T will likely not be prewired for the temp sensor. The easiest way to check is see if the harness on the back of your mirror has only 4 wires going into it. If there's only 4 wires, it isn't prewired.

 

Good luck finding the right pins for the mirror harness too, none of the dealers that I've been to have been able to find which size pins go in there (Although the last dealer found some that they think might work, I just haven't had a chance to try them yet), and I haven't found any similar truck in the junk yard to salvage a harness off of.

Crap, I only have 4 wires: Black Red (or Pink, couldn't tell) Green Blue.

 

Can anyone tell me what each wire does?

So what all will I need to wire up for the temp/compass mirror with auto dimming?

Pins to plug into your harness, wire to run to your temperature sensor, the temperature sensor (About $20 from the dealer), the mount for the sensor (Also about $20 from the dealer), and whatever the auto dimming mirror needs. I didn't hook up the autodim part of my mirror, since my truck has tinted windows, but I think it just needs a wire run to a something that gets powered when the truck is in reverse, like the wires going to your reverse lights.

Did you ever get your temp working?

FYI, My 2000 GMC Sierra had the Electrochromic rear view mirror but neither side mirror was. On my NBS 07, the rearview and the driver's side mirror are but NOT the pass side mirror. I always wondered on my 2000 why they didn't make the side mirrors auto-dimming because the drivers mirror did blind me sometimes, but never the pass side. Maybe because it is convex? On my new truck, the pass side mirror is not auto-dimming and IMO doesn't need to be, it is not an issue.

      primary drive belt tensioner

      By Deadwood · Posted

      I bought belts and pulleys for my '20 L5P at Rock Auto a couple years ago. I have used them for many years, and almost always save significant money, especially when I buy maintenance stuff ahead of time.   They carry many OEM parts, which is all I use unless an aftermarket is shown to be same/superior, or if it is an insignificant part or unavailable OEM part anywhere else. RA is usually lower priced, often by a bunch, but parts are sometimes unavailable or out of stock, and I do shop around and sometimes find better prices at other sites.   Be aware that you pay shipping, and if you buy multiple items and they are coming from different warehouses, the shipping can kill the advantage. Planning ahead is best if possible.   If you have a transmission service in the near future, check out their OEM (AC Delco ULV) fluid, usually MUCH less than anywhere else.

      10L1000 anyone with High Mileage ? I hate Damocles....

      By Deadwood · Posted

      New member here, very long time occasional guest. Saw this thread, thought it would be a good time to contribute someting. It is only my experience and not a claim that everyone will have the same.   I bought my '20 3500 L5P new and have put 99.9% (literally) of it's current ~400k miles on it myself, with over 50% of that towing loads between 4k to 15k, and to me this truck has been nothing short of amazing. For the first 235k I had zero issues, and from there until 321k I replaced a NOx sensor, two failing glow plugs, and three of the notorious injector connectors. I believe this truck is in part, a testament to good luck, but also good care and following a decent maintenance schedule (I also keep meticulous records.) As a result, it looks as good as a well cared for 70k rig, up and down, inside and out.   At some point before that 321k mile mark I began to get a little spooked about the 10L1000, especially the valve body. Word of mouth about potential issues prompted me to jump on the net to sift through all the noise and determine what all the fuss was about. I routinely take long trips, coast-to-coast and points in between, so roadside breakdowns can be '...a thousand miles from nowhere' and a bit of a challenge, and though I had no issues, my guard was up and activated.   And then I stumbled across a chance to salvage some parts off a new 2025 that had been wrecked in transport. I grabbed a few wear items (alternator, pulleys, etc.) and on a whim asked what the ten speeder would cost me. It was cheap...really cheap. I knew some changes had been made in the '24+ version 10L and were supposedly not compatible, but I called service/parts at my local Chevy dealer and asked why and they didn't know. A call to a well known aftermarket transmission outfit revealed it was very likely it would be fine, but to them not 100% sure.   Because it was cheap (really cheap) and I was spooked, I took the chance. Had it installed by a local shop and it worked like a champ, shifted just like the original. At it's first service at 37k, I had the shop put in a Next Gen valve body kit, which after some initial hiccups and rough shifts, smoothed out though with somewhat firmer shifting.   All that said, I have a very serious concern about my newer transmission as just two weeks ago it suddenly began to exhibit a strong reluctance to engage forward or reverse. It was a bit past due anyway so I took it in for service. The reason it was sticking was due to 'glitter' in the fluid clogging the filter...not good folks, often indicates a converter giving out. We ended up going ahead with the new filter and fluid, first to see if it would move and shift, and then if so buy me a little time. It did, and I've driven it over a thousand miles and it is shifting smooth, no noises or slipping. Regardless, it looks like a third gearbox is in my future so I can resume taking long trips with some confidence. In the very short term, my curiosity will have me examining the fluid to check how much glitter has reappeared.   An earlier poster had alleged, in the context of 10L100 failures, that it is another example of how we seasoned citizens somehow descend into hysteria, lose control of our senses, and react irrationally after brief encounters with the idiocy of the internet infosphere. Let me say (and I have used and abused said internet since it's infancy) there is no segment of the populace that has a corner on over-reaction to digital garbage. Just as my offering of experience in this arena is purely anecdotal and should not be considered gospel or all-encompassing, I believe it is still worthwhile information to consider, along with other relevant anecdotal experiences about things like complex transmissions, especially when balanced with other sources.   So to answer the original question, yes I got high miles out of my first 10L, trouble free for 321,000. Now I really wonder how much longer it would have went. Did I 'overreact' to the internet ghouls by replacing a 'good' one with a 'bad' one? Maybe. Who knows, the thing might have taken a puke a 100 miles later. So I'll just fix it again, then move on and start thinking about all the other stuff that will eventually wear out. It still has the original brakes (they're at ~60%), original injectors/pump, turbo, water pump, etc....pretty much original everything. Knock on wood.

      6 Speed vs 8 Speed

      By swathdiver · Posted

      At peak temperature.  They get to cool down and warm up more, especially those with the external cooler.  I have three GMT900s and one of them has over 225K on its original transmission.  Fluid gets changed about every 36K miles, all of it.     It's not the bean counters, it was the government.  They had to meet CAFE standards and other government requirements.   To get around that, we tune them and modify them to our liking.
