Speedo not working

05yukon · Apr 9, 2025

I'm having trouble with my speedometer not reading anything even after I replaced the cluster.

I replaced the cluster in my 05 Yukon because I know they go bad easily and the old one had a few gauges not working. But my speedometer is still not working.

I would appreciate any help before I have to take it to a shop and pay to have it fixed, thank you.

First: Welcome to the forum, from Oregon.

Second: You said you replaced the cluster but what did you replace it with? A used one from a salvage yard or from ebay or....?
If so you may have installed one with a bad speedo. You said your old speedo worked before replacing it. Are you talking about the speedometer or the odometer?

I have had my clusters replaced on my 2005 Tahoe Z71 and my 2004 Silverado K2500HD, from a company called Digital Dash Solutions with never a problem and they always needed my VIN to set the cluster up for my truck and they needed my mileage, so they could put correct mileage on the new cluster.

It sounds like you MAY have communication problems or if is a used cluster, you MAY have installed a gauges working cluster but an inop speedometer.

I replaced it with a new one from a company called ISS Automotive because the speedometer and oil pressure gauge didnt work and the odometer was off by a few thousand miles from the previous owner.

IMO, you should be getting ahold of ISS Automotive about this. Did you contact them? I can only assume when you told them what was wrong when you bought the new cluster and they sent you a defective speedometer/cluster.
