Hey Guys,
I am having a strange speedo problem. Wonder if anyone has seen it and knows a fix.

Sometimes, couple times in the last month, I'll look down at the speedo and it will be reading much faster than I'm actually doing. Say I'm doing about 35 the speedo will read like 90.

When I stop the speedo won't return to 0. Stops at like 60mph or something.

I've found that if I just sit and start the truck up dozens of times eventually the speedo will rest itself.

The problem is in the cluster. It's a common complaint. Defective stepper motor. Time for Esky gauges!

Search stepper motor.

Hey thanks. I did a search... didn't find the link or info.

I'll look at the Esky gauges but think I will try and replace the motor. Already installed a trans temp gauge in mine and won't have to worry about setting the new odometer.

I might screw it up but looks straight forward. Found the motors on e-bay. Just gotta be careful with the solder. Tearing into the cluster is easy. Looks like a $15 fix.

3500 Cheyenne with a tach gauge that will red line at half throttle. :nono: and gas needle that shakes. GMC Jimmy whose gas gauge goes back and forth by 1/4 of a tank. After 40k miles, GM gauges are for display purposes only. Are not intended for actual vehicle facts.

Well finally got fed up with the speedo and swapped out the stepper motor today. Total time to do it about 30 minutes. Cost about 12 bucks. Guys on E-bay charging 150 to do this.

Here is what the speedo looked like when I pulled it out.

Really easy to get the cluster out. Prolly about the 10th time I've had mine out for different things. Drop the steering wheel all the way down. Put the e-brake on, turn the key and drop the gear selector down to low. Then pull the cluster garnish off. Just snapped in. 4 bolts hold the cluster in. Unplug from the rear. Make sure the gauge is reset before unplugging it. All the needles at 0.


Once you get the cluster out. Disassemble it down to the needles. Lots of snaps holding it together. Without touching the needles mark their position. I used masking tape and marked the positions. Pull the needles straight off, then the overlay and continue tearing it down to the PCB board. Just snapped together.


Then its just a matter of finding the 4 solder points of the motor and de-soldering it. A solder sucker or solder wick is necessary to get the solder out of the holes. Pull the old motor off and put the new one in and solder it back up careful not to burn the traces.




Put everything back together to the point of putting the clear cover back on. Placing the needles in the marked position. Take the cluster back to the truck and plug it in. This will reset the needles. Make sure they are lined up. If not unplug it, reposition the needles and plug it back up until they reset back where they were. Took me several times to get them right.

Finished product and working fine. This is back in the truck with it idling. Took it for a spin and speedo is right on.

Delphi settles GM parts issue

Company pays $100M to mend warranty issues and agrees to replace 1.1M electronic parts.

David Shepardson / Detroit News Washington Bureau

WASHINGTON -- Delphi Corp. will pay General Motors Corp. at least $100 million to settle long-standing disputes over warranty issues and also will replace 1.1 million electronics parts -- worth more than $80 million -- at no charge as part of a wide-ranging agreement between the companies.

The settlement, reached Aug. 14 and made public late Thursday, opens a window into the costs GM has incurred in dozens of recall campaigns as a result of parts supplied by its former parts unit. GM has blamed dozens of warranty claims on shoddy Delphi parts, especially electronics.

The companies won U.S. Bankruptcy Court approval to release only an edited copy of the agreement. The agreement resolves all outstanding issues between the companies and sets the stage for Delphi to emerge from Chapter 11 bankruptcy by the end of the year. Troy-based Delphi has filed a final reorganization plan.

Since GM spun off Delphi in 1999, the automaker has had many disputes with the company over warranty claims.

GM spokeswoman Renee Rashid-Merem said Friday that the agreement "clears the slate" between Delphi and GM "and resolves a certain group of outstanding warranty issues."

She said the agreement covers as many as 50 warranty issues; the settlement refers to at least 43 warranties.

The major issue resolved involves 1.1 million electronic parts that are part of instrument clusters, according to a heavily edited version of the agreement that has been made public. The instrument cluster is the electronic brain behind the instrument panel on the dash.

With the agreement and an improving relationship with Delphi, GM hopes to save $2 billion annually in parts costs.

As Delphi exits several businesses, GM will represent a diminishing share of its revenue -- down to a quarter or less than $5 billion by 2010.

Delphi attorney Jack Butler said the agreement saves Delphi "hundreds of millions of dollars in potential liability."

Defective parts replaced

Under the deal, GM will receive $47.5 million to replace defective electronic parts and Delphi will provide 1.1 million new parts at no charge through 2014.

In addition, GM will have a right to buy additional parts at no more than $83 each.

For instrument clusters equipped with Switec stepper motors, Delphi also will provide bulbs and motors at its cost.

In another issue, Delphi will pay GM $175 per repair for up to 107,000 vehicles -- or as much as $18 million. GM would not divulge what part is involved.

Delphi also may sue a supplier over one of the defective parts. If successful, the company has agreed to give GM part of any proceeds exceeding $8 million.

During the dispute, GM withheld $5.4 million in parts payments from Delphi. Delphi won't seek the payment.

Meanwhile, two GM investigations into other allegedly defective parts by Delphi remain ongoing, "and GM has not yet determined if Delphi has any responsibility," according to the agreement.

Hi All,
I have a 2004 Silverado and also have gauge problems. Out of 6 gauges, only the volt and tach are working. Speedo is pegged as far as it will go. I bought the lifetime guarantee (haha) stepper motors from E-Bay:

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=230457892405

I'm pretty good at soldering so I think I'll be okay.

I have a question...has anyone tried to manually reset the gauge needles back to the "rest/off" position and had them work normally? I might try this before replacing them just for the heck of it.

Dep
