90 accord EX speedometer Q.

[doownek]

ok, so im leaving skool today, and i notice my speedometer is not working.... and im dooing about 45 mph, but it reads zero....hmmm i did not look at the speedometer when i left the college, i just looked down about a 1/2 mile away, so i dunno if it did not work at all, or just stoped working all the sudden. all other guages worked fine. hmmmmmm i said to my self, so i pulled over, pulled my key out, and counted to 10, started it back up and the speedometer worked just fine!..... i have NEVER torn into the dash or anyting, so i dunno why it all of the sudden stoped working on me! i been driving it like i have done everyday for like 5 yrs now... never done anything that (would/should?) effect the guages...... so i dunno what happend. it working now, so lets see if it does it again..

has this happened to anyone? and any known reasons? im stumped.... any help appreciated!
