How To: Stepper Motors Repair / Replace
I just switched out the stepper motors in my 03 and thought i would share how to complete the project. on ebay you can order the stepper motors and for all of them (7) was 46.00 shipped to me.
first unhook both batteries!!!! remove the instrument cluster and take the plastic lens off. next move all of the needles counter clockwise until they stop. take a piece of masking tape and tape it on the backing board and mark where the needles are.
next remove the needles by twisting them counterclockwise and pulling up until they come off.
now remove the back of the cluster (plastic) until you see the circuit board. unsolder the 4 pins and remove the old stepper motor. re solder the new stepper motor in. (they can only go in one way cause of the tab that goes through the board)
once those are all soldered in put the needles back on the gauges and turn them so that they read in the same spot that you have marked with tape and a marker.
pull the tape off and put together the cluster and put it back in your vehicle. I tried to upload pictures of all of this in steps but it kept telling me there was an error... good luck to you all!

Cool write-up..you can upload the pictures to photobucket or similar. Use the IMG code and it will show your pictures here. Your photos were probably too big to upload on the site.

Great write up and was easy to follow.
My MPH gauge was shot and the dealer turned me away as far as warranty goes.
I ordered all seven gauges but only ended up replacing the Speedo.
The Gauges were only like $32 shipped so no biggy. While I had the gauge assembly apart I also installed the $28 white face gauge kit commonly found on eBay.
The gauge cluster removed so easily that I'll just replace the motors as they go bad.
Total time to remove the cluster, remove all needles and install the motor and white face plates, about 1.5 hrs.
To remove the cluster and replace any one motor and reinstall, probably about an hour (with set up etc)
Make sure you have a SMALL soldering iron. One you can use on circuit boards. You can find one at Radio Shack for $15.
I love how the white faces look and thanks to the OP, I was able to gain the confidence to do this for pennies on the dollar as opposed to replacing the whole cluster assy at the dealer for $300+

Nice write up, thinking of doing this, my speedo is whacked, stuck at 80 as we speak. Got any pics of the back where you need to solder?
