Speedometer drive motor failure, 2004 Chevrolet 1500 pu. When drive motor fails the speedometer will freeze at a random speed. Since the speedometer is stuck, you must calculate your speed from a start position of where it was stuck. Example: if the speedometer is stuck at 70 mph, and your desired speed is 45 mph. Your speedometer will read 115 mph. If your desired speed is 70 mph, your speedometer will peg out at 110 mph. If you are not aware that the speedometer is stuck when reducing your speed, you could panic, and attempt to reduce speed too rapidly potentially causing a rear end accident. When driving through multiple speed zones you have to constantly calculate your speed, assuming that the speedometer is tracking accurately. In order to fix the problem, the entire instrument cluster must be replaced. My cost was $386. 00. The speedometer will slowly reset, each time the vehicle is started, by 5 mph. Gm customer service acknowledged this as a frequent problem, yet refused to acknowledge it as a safety issue. The local dealer where I bought the truck said they replace 3-4 per month. Where I had the repair made, they have established a vendor that does it so routinely they have a 24 hour exchange turn-around.
