I replaced all seven stepper motors on my 2005 Chevy Silverado 2500HD diesel pickup, but none of them work. I used motors from Caltric. Any help?

Is it possible that the fuse for the instrument panel was blown when your motors stopped working? It's almost impossible to confuse where you solder the motors to the board on the back, and I can't imagine that mistake happening to all seven. Also, if you didn't watch any videos about how to deal with the needles, they may be working, but unable to move if you did not replace them or reset the motors the proper way. Other than those two options, I can only think that your wiring harness is compromised.

When I did this I found some of them didn't work, I was able to reaolve the problem by ensuring that not only do the connection go through the board but that the solder contacts the circuitry on the board. Also check for a blown instrument cluster fuse.

I would recommend you verify voltage feed to the cluster. I have used these exact parts to repair 2 gm clusters in the last 6 months. Both work flawlessly. Also visually inspect the cluster PCB to verify that nothing was damaged during the repair process. I had one of the surface mount diodes get knocked off the PCB during disassembly on my first cluster repair. Hope this helps a little.Good luck

It worked for me ! I was familiar with several types of motors and I was not sure how the speeds changed. When I took the connection cover off and saw the capicitor, I thought it was the problem. The color code on the leads helped me find a replacement.

IF your motor quit working, then this motor only fits the newer gearbox. I purchased the motor and it would not fit the older gearbox( I have a 95 Cobra). If the motor runs, and the gearbox wont work- simple fix- open gearbox and put 1/4" nuts (3) where plastic balls go. To fit the new gearbox to your steps might need some spacers to line up properly- sure cheaper than new steps or a trip to the repair shop-.

I have a 2004 Silverado 2500HD, an it works perfect. I have LEDs all the way around, no fast flash and my cruise works great...

Good luck! Chances are if these need replacing, the engine is not far behind. I replaced mine at 85,000 miles. The engine didn't make it to 115,000. Had to get rid of the truck! Such a sad design.

If the old screws came out clean they should work fine as the screws tap the base of the replacement motor. The old screws sometime break when removing, is why some suggest new screws.

Marcie, I think you are missing some letters off of that serial number. That number alone does not pull anything up. Can you either supply us with the horsepower or contact us for help in determining the correct kit for your motor 877-388-2628

Chevy's work by switching the grounds (turning them off and on for high and low beams) You need to test your wiring, some newer vehicles already have this option. Check the socket for power on both high and low beams when on hi, if you have power to both, you do not need them. If you do, there is a specific relay setup for the chevys. Tim

I had the same problem and found the controller was not connected well. The battery connections are not very user friendly either. I took the motor and connected directly to the battery and it worked. I then checked power out of controller when I forced a turn on, all worked fine. So, it knew it was a bad controller to motor connection. I kept on messing with the connector , controller to motor, and it finally started working. I am talking about the connection inside the hopper that connects motor to controller.

I use mine to replace stepper motors and bulbs on the circuit boards of dash gauge clusters and it works great. It works great to desolder and solder . I have not messed up a circuit board yet.

Check the blades, you may have put them on the wrong motors. Try changing the blades and putting them on the opposite motor and see what happens

I have these on my chevy 2500hd with no issues, I went with an led flasher instead of resistors. It sounds like you might have a short in the wiring or one of the leds.

to fmake sure call the parts department at a chevrolet dealer ship they can give you the part number thats how I found the correct one for my silverado

Yes, I replaced all 7 on my 2004 Silverado and they continue to work great. There's no reprogramming that I know of but the videos on YouTube are very helpful. You need to be able to unsolder the old ones and solder in the new ones.

I had to replace the controller when I replaced the motor. You might have to replace the motor when you replace the controller. It's a voltage thing. I did not have to replace the door switch. You will know if the step does not operate correctly.

According to amazons search engine this part does not match. The other thing is weather you have flex and not regular motor. Have to be specific on this. Pull a plug to get numbers on it. If not call your dealer for part number. Tell them your trying to figure out of plus you have are correct. Bs'm when looking up on amazon two different numbers pull up either old and new, or flex and regular. Good luck

Probably, I have a 2005 chevy silverado with 5.3 and it worked for me. Try taking to old one off and remove the Large top and wash it out. I took my old one apart and that was the problem with it.
