SOURCE: THE SPEEDOMETER STOPS WORKING WHEN

If everything else works ok, the vehicle drives normally, and all the other gauges are working then you may have a bad speedometer servo motor. This servo is what actually moves the speedometer needle to match the speed you are driving at. The cluster would need to come out and be repaired to fix this problem if this is the case.

SOURCE: my speedometer stop working

It's a bad stepper motor (the device that operates the needle on the gauge).  Replacements can be found on eBay for approx. $4.95 each - just search for "stepper motor".  Just got 6, to replace all of mine.

SOURCE: M y radio stopped working on my 2004 trail blazer

The 2004 Trailblazer has two fuse panels, one in the under hood and one under the middle row seats. The radio fuse is marked RADIO fuse # 41 and is a 15 amp fuse located in the rear fuse panel. To access the rear fuse panel flip the seat behind the driver to the upright position, under it you can see the fuse panel and a diagram should be on the under side of the cover. 

Good luck and hope this helps.

2001 blazer chevy

The ABS light is on, because you have no speed signal. The transmission is not shifting for the same reason. The core of your problem is the speed signal. I would first check the speed sensor wires again. One of them may be broken. If not, then you may have popped the ECM (Vehicle Eletronic Control Module). Good luck.

04 chevy blazer speedometer

sounds like you have a bad speedometer cable - these will make the numbers 'stick' because the cable slips --

Also - take down the vin number and call the local dealer - ask about any recalls or service bulletins
