Just trying to think of something that would effect all those systems at once intermittently...possibly a bad ignition switch? Bad connection in the power distribution center?
You mean I'll try to replace ignition switch, but is there any way to check current ignition switch is bad or not?
What includes in power distribution center?
You would need a service manual that shows the pin out of the ignition switch, but yes, you can test it with a multimeter. Check for ohms through the switch while doing a jiggle test.
And the distribution center, you would be looking for areas that have gotten hot that would indicate a poor connection and high amp draw creating too much heat and causing the plastic housing to melt.

You have clean the blower unit , may be its dirty then . and then check the blower resistor unit for malfunction.
SOURCE: speedometer intermittently stops working
your ABS module (board) is crack and a good fixman could check that to fix or change it
SOURCE: p0500 speed sensor code, odo and speedo not working
If one speed sensor goes out, it will make your speedo stop working. I believe the sensors are about 200 a piece. You'll have to take it to the dealership to find out which one is malfunctioning as there are 5 of them total (I'm pretty sure). They only charged me 30 to put it in as it is really easy and that way it is warrantied by them.
One other problem I had was with the electric brake controller on my truck went haywire and when I disconnected it, my speedo came back to life.
Hope this helps!
