I have found that when you are going to engauge 4x4 high, it is best to only be going about 3 miles an hour. Not faster, not stopped. It likes some movement to help it mesh. I've had perfect shifts since I started this. Hope it helps. Wade.

SOURCE: How do I remove and replace Corolla 2006 blower motor?

Well the blower motor is underneath the dash on the passenger footwell, you have to remove the glove compartment to gainaccess to the blower, it ahas 3 or 4 bolts holding the motor, remove and replace with new unit, it is a good idea to replace the filter once the motor is removed.

SOURCE: I changed batteries in my 2003 GMC Sierra key fob

1. Close all doors
2. Insert key into ignition
3. Hold down the power UNLOCK button on the driver's door panel, continue to hold down
until instructed to release in step 9.

4. Perform steps 5 through 8 in a fairly rapid succession.
5. Turn the ignition to the ON position (as far as you can go without starting the engine.)
6. Turn the ignition to the OFF position.
7. Turn the ignition to the ON position (as far as you can go without starting the engine.)
8. Turn the ignition to the OFF position.
9. Release the power UNLOCK button on the door panel. The vehicle should respond by
door locks locking and unlocking automatically. (If locks do not cycle after you let go,
not before you let go of the unlock button, then the vehicle has not entered programming
mode and you must start procedure over. Remove key from ignition, open drivers door
and return to step 1 ). If the locks do cycle automatically then proceed to step 10.

10. Hold down the LOCK and UNLOCK buttons on the remote until the doors lock and
unlock. This may take up to 30 seconds.

11. Repeat step 10 NOW for each additional remote. (Including any existing remotes).
12. Turn the ignition to the ON position to exit the programming mode.
13. Test remote(s).

Speedometer doesn't work

You might try an oil pressure sending unit, first making sure the connector and harness are okay. I'm not sure, but I think there is a VSS Sensor as well, or vehicle speed sensor. Check the connector and wiring. If its okay, try a sensor. Good luck, hope this helps.

My speedometor does not reed the proper speed it will reed 100 when you are not moving

The stepper motors on the dash board instrument panel are bad. There was faulty motors and you can buy them on ebay. In order to replace them you have to take the instument panel out, (go to youtube for the video) then you need to unsolder the old motors and solder the new ones in. I had never done something like this and took about an hour to replace two motors one on the gas guage and the other on the speedometer. They take the same stepper motor.

GM had gauge cluster problems from 2000-2005. Bad stepper motors. On those units you have to replace the cluster or rebuild it with new stepper motors. Dealership fixed mine for $150.00

I have worked at a chevrolet dealer for 12 years and have probably replaced a few hundred of these clusters. the speedometer portion of the cluster always goes out, I have had very few speed sensors go out, and when they do the check engine light will come on and the trans. won't shift, if the new cluster is too expensive they are easy to replace if you just buy it outright, you can also get a wrecking yard cluster your miles just won't match

Replace spedometer cable 2003 gmc yukon xl

There is no speedometer cable on the 2003 Yukon, if there is no transmission issues like shifting problem. Your instrument cluster has gone bad, to pinpoint. Your stepper motor to your speedometer gauge has failed and needs to be replaced. You can do a search on Ebay for the stepper motor for around $10.00 which is better then the $400.00 cost of another instrument cluster.
There was a TSB on the replacement of the instrument cluster for your Yukon free of charge. The only cost to you is the labor charge unless your willing to do the job your self. Just go to the Gm Dealer and give them this TSB Number: # 07187C: Special Coverage Adjustment - Instrument Panel Cluster Gauge Needle Function - (Mar 20, 2009)


Some customers of all 2003-2004 model year and certain U.S. 2005 model year Cadillac Escalade, Escalade ESV, and Escalade EXT; Chevrolet Avalanche, Silverado, Suburban, and Tahoe; and GMC Sierra, Yukon, and Yukon XL vehicles have reported that one or more of the instrument panel (IP) cluster gauges stick, flutter, or become inoperative. This may cause inaccurate readings, including the speedometer and fuel gauge. Special Coverage Adjustment This special coverage covers the condition described above for a period of 7 years or 70,000 miles (110,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership.
Dealers are to replace the instrument panel cluster after the condition has been verified. The repairs will be made at no charge to the customer.

For verified failures between 70,001 miles (110,001 km) and 80,000 miles (130,000 km) on U.S. vehicles, dealers are to provide the customer with an instrument panel cluster (IPC) only. Any additional costs, including labor to replace the instrument panel cluster, will be the responsibility of the customer. Dealers are responsible for the return of the customer's IPC back to the Electronic Service Center

Thank you for using fixya and good luck.

Speedometer cable how a 1500 gmc siarria

They don't have cables, the speed signal is delivered electronically to the computer then to the instrument cluster. If your gauges aren't reading correctly it's most likely due to failing stepper motors on your cluster's circuit board, very common on all 03-06 GM vehicles.

The stepper motors in the dashboard are bad. This is a known problem on these vehicles. Stepper motors can be bought on e bay for about 6 bucks each. they are not hard to do but you do need to know how to solder the old ones out and solder the new ones in.

Speedometer doest work how do i fix

You dont have to replace the cluster. Just replace the stepper motors. They are not difficult to do. I replace three of them and all the light bulbs in my 2004 gmc just yesterday ,, It took me three hrs from start to finish. The light bulbs are more difficult to replace than the stepper motors. Stepper motors are available on e bay for 6 bucks.
