Speedometer trouble
My 04 silverados speedometer stuck at 20mph tonight. I drove the truck for a few miles before stopping. When I turned the truck off and started it back it dropped to 10mph and started working but it was way out of calibration. When I turned the truck off the second time it dropped to 0 and seems to be working fine now. Any ideals as to what may be going on.

RE: Speedometer trouble
It may be your speed sensor, or your speedometer gauge. If the sensor is sending the wrong signal it will read wrong, if the gauge is broke or wore out it could read wrong. If you have a repair manual for it you may be able to put a set voltage to your speedo to check it. I don't know how to check the sensor.
I would look ina book.

RE: Speedometer trouble
It is caused by a faulty stepper motor in the gauge cluster.
If your truck is no longer covered under warranty then you can repair the cluster yourself.
New updated stepper motors can be purchased and installed with just basic soldering skills.
The motors are available on Ebay for about $10 each and generally included good instruction, I recommend that you replace all 6 motors (1 per gauge) in your cluster while you have it out and apart.

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.
