If your speedometer is inaccurate or erratic and you've replaced the VSS (vehicle speed sensor) with no success you may need your PC board repaired. I'm a Honda/Acura service technician in NC full time and repair Honda electronics as well. I'm fairly new to the electronics repair world, but in the past year I've had much success in diagnosing and repairing Honda circuitry...saving customers money. If you need any help diagnosing/repairing your Honda/Acura let me know. I would be glad to assist in any way. I'm offering speedometer PC board repair for a great price of $70.00. Is your bower motor inoperative, or only work on high speed? This may very well be caused by your "Blower Power Transistor". I sell refurbished units for $35.00 for all models. The bigger units for the Pilots and MDX's can be around $130.00 from the dealer. I repair other components as well. I offer a 30 day money back guarantee. Let me know if I can be of assistance in diagnosing/repairing any of these circuits/components. Thanks for reading.
