My speedometer does not work, it flutters or pegs out all the way. Only when its hot outside or I have been driving my vehicle for approx 30 mins, the speedometer quits working. This problem has been ongoing now for the last 2 years. I have researched and found many reports of this problem. A search online shows the amount people having trouble. On a newer model it might be a malfunctioning sensor or bad electrical connection. Put the cluster less the front lens back in the truck, with the cable plugged in.
I have been the soul owner of this vehicle since I bought it off the lot in 2004. I was hoping this was a recalled item. The problem seems prevalent with all Tahoes. Speedometer can stick at excessive speeds indicated on the cluster, this had intermittently effected the cruise control operation. The driver also stated that there were intermittent failures with the electrical system. Figure out whats causing it then you can remedy the situation.
Examine your solder joints carefully. I won't be able to get my vehicle into the dealership until next week. Anyone know if it will be any different? The failure mileage was approximately 48250. Pull the tilt wheel all the way down. Twist each needle a little counter clockwise to break the bond between the needle and the stepper motor. I cannot tell how fast I am going.
All of the info here and on other forums has been such a big help I thought I would share. The approximate failure mileage was 206,530. We want suck, not blow. It uses spring retainers so pull it straight back. On a web site I found it talked about a mileage limitation, all work free till 70,000 miles and truck must have a vin inside a particular range.
My speedometer does not work, it flutters or pegs out all the way. Just recently the tac stopped also. Additional, the electrical system is out of whack. Oil pressure sensor reading wrong. We lent a ton of money to gm and they need to be called to the carpet to remedy these issues promptly. The speedometer indicated 30 mph, but the contact stated that the vehicle was traveling slower.
Issue started with my vehicle at about 78k, but was not brought in by me to gm because there was not an announced recall. Example; when you push the lever to move the seat forward it goes backward and vis versa. Very frustrating and dangerous if this happens on a busy highway or freeway. One or more stepper motors. This is a severe safety issue and this defect is a problem the manufacturer should repair at no charge.
I did replace all 6 motors. It's now been a few days and the speedometer isn't working correctly at all. The dealer has been the only place that can actually get it to unlatch and admits it a bad design. Sometimes, especially when it's cold out, the speedometer will stay at 0 mph and not even move - once it does get going, it go up, but when I come to a complete stop, it won't go back to 0 - it may stop at 20 or 30. I'm guessing however that this is not the way they would fix it. I am unable to tell how much gas I have or how fast I am going. The vehicle was taken to an authorized dealer for inspection, but they were unable to determine the cause of the failure.
The vehicle was not repaired and the manufacturer was notified. Cluster replacement is the cure. I didn't have any solder wick or a desoldering pump, so I used compressed air to blow the hot solder off the joints. This is a safety hazard. Is it the owners fault that the vehicle didn't error before this so called unfair time line? The speedo actually started skipping around as I was driving the truck around yesterday.
Take out the 4 screws 7 mm head that hold the cluster in. The guy that sold me the stepper motor recommended pushing the needle on pointing at mid scale, then twisting to the bottom of the scale. The some of the drivers seat controls stopped working or are reversed. It was easier than I thought it would be. When I am at a complete stop, it shows I am going anywhere between 50-70 mph.
