Was driving down the freeway, noticed i was doing 125mph with less than 2k rpm. i knew it was wrong. so parked it, and the speedo doesnt go all the way down to zero. it stays at aroun 20mph .
sometimes i will rest at 15 or 10 or 30 mph. sometimes 0. what is goin on??

please help

Speedo broken. Many have had this problem. Take it to the dealer, or get a replacement cluster. Do a search for Speedometer, tons of threads about this.

As Denaliano said, it's the stepper motor. You can buy replacements on ebay for around $20 and replace it yourself if you have soldering skills. If not, there's at least one guy on ebay who will sell you the motor and install it (for a fee of course). I think he gets around $100 to replace all the stepper motors on the panel.

But it is a good time to upgrade to an Escalade Cluster. I'm glad I did.

this happened to me today. is this covered under the warranty of the truck?
Yeah it should be covered. I'm waiting for a recall to be issued so I can be re-imbursed for the cluster I had to buy since my truck was out of warranty.

I knew somebody here spoke of a recall notice they had received, but couldn't remember who until now. I'll wait a few weeks, then end up at the dealer if I don't hear anything. I'd like my $340.00 back please.

I hear ya. I'd bring mine in but i'm over 70k and will not buy a new cluster.
