Speedometer doesnt work sometimes..WHY????
Its an 03' k1500 with 50k miles on it
it is electonically controlled. You might be having an issue with a faulty speed sensor.
I would get a new speed sensor, but you may also want to check your relays and fuses as well. Speed senors are just a laser beam that it usually located near the tire areas, depending on the year of your truck that is. But yea, check your fuses and relays sometimes they are either blown or the relay is no good.
Check the wiring at the speed sensor. Sometimes connections open up or come loose. The speed sensor is connected to the transmission.
One key element is that when the speed sensor stops functioning the transmission will have shifting problems between gears
you are thinking of abs sensors. speed sensor is located in the side of the transmission. relay is a possible cause. fuse is not since the problem is intermittent.
my 1989 chevy does the same thing but i think their is somthing partly wrong behind the gauge cluster but when mine quites i hit the dash to get it to work
yea I know, I tend to talk out of my ass to much and etc etc ... wasn't sure where the sensors were located ty for tellin me. and it could be the relay, I can't think of anything else...
Mine does it also in an 88. I hit my dash and it works, when I get time I'm going to take the dash apart and se if there is a loose connection or something. I also have problems with the turn signals, ABS light, speedo, and shift light, from time to time.
