Great little upgrade on the rear view mirror that quickly becomes a “BIG” upgrade as you get in the habit of looking at it to use the information. The ambient air temp sensor is a positive temperature coefficient thermistor in a clip on/bolt on housing. Simply called a PTC thermistor, the colder outside, higher resistance, drops gently on a downward curve as it gets warmer. Very little current runs thru it but for those reading, alway use both wires. It is what’s called a dedicated ground directly into the display circuit. Never use the chassis for ground as too much resistance, even low throws off the reading. Good catch on the cold soldered 403 years ohm resistors. They are in series and one end cracks, goes out or intermittent. Also, getting the face off the mirror, tabs are spaced equally around outer edge. A 0.90” thousand feeler blade works well and use two or three as you work it off. Never use a pocket flat blade screwdriver as even those are way to thick & will make ugly marks. SnapOn sells the blades separately from the entire kit but HF will allow you to get 3 or 4 kits and work the same. Power or ground turns on a “Dichromatic” mirror dimming for all 3 mirrors. (Your May vary / Review schematic for correct year / GM and others have wires & connector, colors and proper cavities) Go to dealer and ask a tech who will print for a six pack or $5. Each tech have a terminal but may share with 1 or 2 techs. Nice job for a cool upgrade as I put one in a 1967 C10 without “On-Star” and changed circuit board from “SIR” to Select to switch. 6-8 regional GM AUTH SHOP, but a number of shops do these and may sell “Soft Button” cover, even face plate. Great job of swapping out. It is work to video, prep, review, edit then upload. Takes longer that changing the mirror, right? Nice. ASE Master Tech since 1978 - Retired
Thank you!!! Been needing this for my 99 LS Silverado 2500! If you could find a way to get power/heated mirrors on this model as well, that’d be sweet. Rock on!
Fixing to buy a truck similar to this but its a 97 cheyenne 3500 dually. Do i do the same exact process as you did on yours? Can i tie in the red 12v wire with the fuse for power to the radio?
Thanks for the tip on the resistor repair at the end of the video. My mirror died the same way. My base model 1999 Silverado had a plain mirror. I grabbed one like yours from a parts truck and installed it in 2015, Looking forward to attempting the resolder tomorrow.
They're not chips, those are resistors. In my case, the voltage regulator on the main board was also toast, had to replace that too. Just look around and try to spot some scorch marks or cracked solder joints and sometimes, obvious probles might stand out.
I tried wiring it in I bought the harness and sensor but it’s still saying open circuit does the wire location matter on the sensor? They came only white so not sure
Will the auto dimming work for a 05 cateye 2500hd work truck model truck no power windows or anything at all straight up work truck,I want the dimming the outside air temp an direction of travel
my mirror harness was tucked up inside the headliner. added a mirror and a temp sensor and bam. 2000 silverado with power windows. i've heard if the 99-06 trucks don't have power windows, they wont have the mirror harness tucked up inside the headliner.

You get the mirrors and the window switches
Fixing to buy a truck similar to this but its a 97 cheyenne 3500 dually. Do i do the same exact process as you did on yours? Can i tie in the red 12v wire with the fuse for power to the radio?
So how do you enable auto dimming?
Good job 👍
You are the man!!! Thank you for the vid it was exactly what I was looking for!!!!

Just left the junkyard! About to update my 99 Silverado! Great video, thank you 😊
wish they could be changed to red or white display
Hell yea great video thank you
Thanks!!
Cool mine stops working once in a while to, I’ll try this before getting a new mirror
Where did you connect your ground?
So did the green ground mess it up? Or r we ok to still ground the greens?
Great videos. Simple useful info.
Different location
Could I possibly install this Chevy mirror in a 95 Camry??
Yes. As long as the mirror will Mount to the windshield
@@EndlessWishlist and run power to the mirror
Will the auto dimming work for a 05 cateye 2500hd work truck model truck no power windows or anything at all straight up work truck,I want the dimming the outside air temp an direction of travel
Yes it will. It has a light sensor on it. So you would just need to wire it the same way I did
@@EndlessWishlist the sensor on my dash is missing wasn't on it when I bought it 3.5 years ago will that effect the dimming mirror?
The sensor on the dash is for your headlights. The mirror itself has a light sensor that dims when there is someone behind you at night
@@EndlessWishlist oh hell yea man that's awesome
Where did you buy the new sensor? I have the mirror but haven’t installed it.
I got it from the parts Yukon. If you want a new one get it at rock auto or something.
Endless Wishlist thank you I’ll start looking for one!
Which cable was it the red and black and the green and the black with white?
Where do you get those wiring diagrams?
Just googled auto dimming rear view mirror wiring diagram
Where did you find the wiring harness for the electric cooling fans?
Pick and pull
Amazon
my mirror harness was tucked up inside the headliner. added a mirror and a temp sensor and bam.
2000 silverado with power windows. i've heard if the 99-06 trucks don't have power windows, they wont have the mirror harness tucked up inside the headliner.
I mention that in the end of the video. My 2002 had the harness in the headliners.
@@EndlessWishlist your 2002 has power windows correct? I had read that the non power window trucks don't have that mirror harness. I can't confirm.
Yes my truck has power windows
Endless Wishlist hey I found the same thing on my 99 Silverado. I’m getting an open circuit error on the mirror. Any ideas?
Yea you don’t have the sensor install. My 2002 had the same thing. I just ran my own wires and got a sensor/pigtail from the junk yard
