Just finished the repair on my 2003 Avalanche. I had two broken traces on two of the three resistors that you hit at first. I resoldered them, put it all back together, and back in the Avalanche. The compass and temp display came on like new. I've been living without those for many years. Thanks so much!!!!!!!!!

[@ml2755]

Thank you! This is a perfect example of a video walk through the DIY community needs more of. Straight to the point, good lighting, and clear audio details. I fixed the faulty solder joint and it now works like new.

[@jeffescortlx]

Thank you!

[@mercible]

Thank you! Just saved money by using the soldering iron I already have, and a good pair of reading glasses. I could see a visible crack in the solder weld on one of the three dropper resistors you pointed out at 3:30. I heated up the solder joint, added a bit of new solder, then did he same for the other 5 contact points, just to be on the safe side. Reassembled, put back in the truck and when I turned on the ignition switch, everything worked like a charm! Thank again!

[@markraygosa7771]

Thanks. You made a great video. It took me less than 30 minutes following your instructions. I now have a working display.

[@chrisjohn5273]

You Nailed it!. Two local auto shops wanted $500.00 for a new rear view mirror + labor$$ to install. This video gave me the detail I needed to disassemble the mirror. I did find and repair bad solder joints. Thanks for the effort you put into the demo video. Cheers!

[@woodstock9029]

Dude, Thank you so much for making this video. I own a 2003 GMC 2500HD sierra, my brother bought this truck new and sold it to me 10 years ago. The compass/temp never worked. He said the dealer wanted a lot of money to replace it so he never bothered to. It was the tiny things you re-soldered first that one of mine had a crack in the solder. I fixed it like you did… except much more rudimentary, and it works now. Can’t thank you enough. I can’t believe how tiny this stuff is, but luckily i had a magnifying glass ….

Awesome video. This is the first time Ive ever touched a solder gun and bought one to change the lights in my cluster. everything but my lights came in today and i just had to use it on something so I remembered my mirror stopped working. Works good as new now. I didnt have tool like yours, but a 1 inch putty knife slid down the edge did the job perfectly for anyone else looking for something that wont mar plastic

[@zugnonid]

Thank you so much for posting this! I had a customer come into my work today complaining about his mirror and this video helped me fix it!

[@jeffescortlx]

Glad it helped!

[@DennisBernth-hu4co]

Just resoldered all six traces on the three surface mount resistors. My senior eyes couldn't make out any breaks, even with readers and a cheap magnifying glass, but I figured I'd do it anyway. I used desoldering wick to remove the old solder and resoldered the joints. Works great! Had it working off and on until 6-8 months ago when it quit altogether. Now it's back! Mine is a 2001 and is the same setup.

[@josephdurkee8540]

Great tutorial. Had been going months without the temp and direction. Was the exact same resistors that had a cracked connection. Thanks. Fixed in less than an hour.

Would you create a video on replacing lamps on the climate controls? Or maybe the airbag controller? I’m honestly not sure how difficult those repairs would be, just thought you might be looking for video ideas.

[@scottj1540]

Thanks brother, your fix was right on the money. Problem solved!

[@jeffalan6339]

The mirror in my 03 Silverado, at first before failing was in Celsius. After that was intermittent operation. I bought GM replacement, plan to keep the oem if so when the replacement fails combine the 2 to make one.

[@RYTHMICRIOT]

Unfortunately, I think I may have waited too long for this repair. My mirror compass began flashing some time ago. I discovered a forum that explained the solder joints on the 3 resistors directly behind the display. Mine looked fine, but I reflowed them anyway. No change. Still had the intermittent flash. I just drove it that way for some time and eventually the display quit working entirely. I decided I'd give it another look yesterday, and stumbled on your video. Sure enough the resistor directly next to the white connector was bad due to a failed solder joint. I successfully resoldered the connection and reassembled the mirror. I plugged the mirror back into the vehicle and unfortunately, the display is still dead. I suspect the problem was exacerbated due to not correctly repairing the mirror when the problem started. There is a chip on the board that sits adjacent to the resistor I resoldered that is pretty burnt. I will likely find a used one now, but when it starts to fail, I will be ready.

[@jeffescortlx]

Before you give up on it, it's possible the 5v regulator may have died. This can be repaired.

[@RYTHMICRIOT]

@@jeffescortlx Thanks! I'll look into it.

[@jeffescortlx]

This is a re-upload video. I've edited the ending of the video to show it being tested.

[@russellhltn1396]

You're a brave man to assemble before testing. ;)

[@rollingtones1]

11:24 since the two photocells are on an analog comparator circuit, you can have the display come on brighter if you block the rearward facing one with your thumb while you are shining light into the forward facing one, because the circuit measures the difference in light levels between the two. The same thing works in reverse if you block the forward one with your thumb and shine a light into the rear one.

[@doug900S]

Which will give you, or should give you a brighter compass in daytime?

[@brianrasmussen2158]

This was the correct fix for my 08 2500hd LMM LTZ. Thank you!

[@nemodetroit]

Good video. I had to reflow the solder on four of the larger 4R3 resistors. One had completely broken free. I suspect this is so common on these mirrors because they used lead-free solder which is more brittle than traditional, lead-based solder. Plus, these particular resistors are low-ohm value (4.3 ohm) and probably saw more heat cycling stresses.

[@jeffescortlx]

That is correct!

[@sxs4l245]

I'm in. I love to learn stuff about things. New subscriber here. Thanks.

[@rollingtones1]

0:23 there is a front facing and a rear facing photocell, and inside the mirror there is an analog circuit that compares the difference in light levels between the two, which then drives the auto dimming function of the mirror glass. These two photocells are only for dimming the mirror glass, they have nothing to do with dimming the highbeams. That is a separate circuit and it is a separate item mounted elsewhere on the vehicle.

[@MP-us7jx]

Just did the same repair on my 2004 Subaru wrx wagon. Different surface mount components (looked similar) and location, but same problem and fix. There were 6 large ones and two small ones. I hit them all with Flux and solder and now it fully works. Thanks Jeff! Also thanks for taking the time to show disassembly. Taking the bezzle off was the hardest part. Where did you get those pry bars? I want some. I used two medium and one thick-/stiff guitar pics :-)

[@doug900S]

Very cool! My dimming and garage opener both work, but my compass got dimmer and dimmer, and now doesn't display. I'll check the circuit board. I have been an electronic hobbyest for years, so I'm anxiuos to dive into it. Mine is on a 2010 Saab 9-3 XWD (GMized if you will). Thanks for the awesome video! Take care!

[@aaronarjes9086]

I have have an 07 took apart last night looks great. I gotta keep looking for the trouble somewhere else. Sometimes it works, but when it does not work many display panel do not work either. I found starting at one of the corners is easier to remove the bezel.

[@stopthephilosophicalzombie9017]

Thank you! I just scored one of these from the junkyard to practice on so I could just swap it out for the non-working one in my Forester. At the worst I'd have two non-working mirrors. It ended up being the same resistor, which was very hot. Should that temp come down if it is soldered correctly or is there another problem in the circuit elsewhere?

[@jeffescortlx]

Those physically larger resistors will get hot, but shouldn't darken, smoke or stink.

What are you applying to the board before you solder and what are you using to clean it up afterwards? Where can I get some?

Flux. A link is in the description. The clean up fluid is just rubbing alcohol.

Thanks. Is there a flux that you know of that doesn't have a 1 year expiration? That product would probably last me 10 years.

[@daveh2612]

Fentertainment probably the wrong sensor. -40 is the lowest the mirror can display and normally shows that when the wrong type of sensor is used. If the circuit to sensor was bad or unplugged , the display will show OC for open circuit.

[@Fentertainment]

@@daveh2612 I bought another mirror from lkq that didnt have onstar and it's working fine. My truck didnt come with the ambient temp package but now it does. The first mirror I picked up had onstar built in.

[@hydrocarbon82]

@@Fentertainment GM seems to have at least 3 different sensor scales, but they're all lower resistance so they'd show up much hotter. No sensor gives you 0F so my guess is your mirror had a damaged chip or board.
