lately i been having a problem in the morning when i start up my truck my speedometer doesn't work for about an hour sometimes if i turn it off and back on after it warmed up it will jump to speed I'm not sure what it could be because it doesn't work some times also my ABS light comes on once a while if that has anything to do with it?? thank you for any help

It may be a bad instrument cluster module or a bad speedo sensor.

Could be a plugin or wireing issue to or from the sensor randomly makeing and breaking contact.
