The same stepper motor drives all gauges in the intrument so it is best to replace them all. Try not to apply more heat to the board than is necessary to quickly melt the solder. I noticed that the needles move freely upward as if it isn't engaging the gears in the stepper motors. Now you can pop the motors off the front of the board once all the old solder has been removed. Commonly, fuel gauge failure has led to drivers being stranded along the road as they attempt to measure their fuel by miles driven on the odometer.
The second cause is due to surface insulation resistance failure on the board. It is a 45 watt soldering iron with a hole in the tip and a rubber sucker bulb. We remove these motors from instrument panels daily. They then send your old instrument cluster to their 3rd party repair partner to be rebuilt and sold to the next customer needing it. Now that you've made your calibration marks firmly rotate each needle further counter clockwise a few inches. I sure don't want to have to send the cluster off to be fixed. This common issue is not actually a problem with the digital displays themselves as they seem to be quite reliable.
Put back the 4 retaining screws and the dash bezel. If it's they're too difficult to remove you need to suck off more solder. Because of this at home installation of a factory trans temp gauge is not feasible. Move on to each gauge using the same technique. I am a 47yr old mom of 5. Please only post in this section if you have directions on how to do a modification, complete a task, or steps to take to resolve a problem.
I bought an air bulb solder sucker from Radio Shack and it did not work well, or it just takes more practice than I was willing to invest - next time, and there may well be a next time, I'll try the copper mesh for removing the existing solder. Dim, Dark or Dead Display This issue is most often cause by a failing power supply circuit on the circuit board which requires either replacement components or a solder re-flow. This can still be fixed but you'll need a shop to do it. Removing the cluster is most of the work, don't pay someone else to do the easier part of the repair. Just unclip the back cover to seperate it. Since that happened and because I have dash lights and the digital display at the bottom of the cluster, I guess it can't be any fuse or anything other than either the motors or the soldered spots.
Remove light defuser, and white plastic housing. One is a faulty selector stalk button on the circuit board which can be replaced with careful de-soldering and replacement if a suitable replacement button can be found. Don't you hate it when as soon as you switch on the ignition, the gauge in your instrument panel thinks your car is moving 88 mph? One down, 6 more to go. Within a two day period my oil, temp, and fuel motors all went crazy prompting me to fix this once and for all. If the oil pressure sending unit checks out then you know the oil pressure gauge is bad and needs rebuilt.
Once I had the solder removed, I gently pulled on the old stepper motor and applied a little more heat to any pins that were still stuck. See pic of a damaged board. The second and perhaps better option is to have a factory transmission temperature gauge installed into your original instrument cluster. Last year my temperature gauge was getting stuck after I turned it off. The settlement allows the owner or lessee to get their instrument cluster replaced under the terms of a special coverage adjustment to their factory standard warranty. This may take a couple tries.
I just replaced the stepper motors in a 2004 Denali cluster and took lots of pics. I have done the occassional flat tire, checked oil and have almost always pumped my own gas, but other than that i know nothing about cars. The gas gauge and the speedometer were acting up. I was lucky I guess, and had everything work the first time. Be aware of generic brand stepper motors produced in China, numerous problems have been seen with these aftermarket motors.
You saved me a lot of money, the goober dealership said they wouldn't cover my truck because it had over 70k miles. Just carefully lift it straight up, it isnt secured to anything. Ok now you'll need a few pieces of masking tape and a pen or marker. There are 11 clips on the back of trim panel that unsnap when pulled gently. Push until the locks click.
It has lock tabs at the top and bottom to hold it to the white part. You have to remove all the needles even if you are only working one stepper motor. Be careful not to scratch your face plate. Here you will find out everything you need to know about its fuses. A small flat blade screwdriver. Twist each needle a little counter clockwise to break the bond between the needle and the stepper motor. Unplug your soldering iron and desoldering tool.
