Speedometer Failure

[Nurega]

My father just borrowed my Accord for a 400-mile drive. About 200 miles in, he calls and informs me that:

"The speedometer dropped from 80 to 0, and within a minute resumed operation."

After this happened three more times, the speedometer resumed normal function. The tachometer, fuel gauge, etc, were all completely functional. Only the speedo and odometer were having problems. Can anyone tell me what this problem could be? The first thing that comes to mind is the VSS, but I have no personal experience with this.

#2:
About 300 miles into the trip, my father found that the left-rear window would not raise back up. He ended up stopping to manually push the window back into the closed position.

This is the first time in 20 years that this car suddenly started showing problems, which is why I'm especially concerned. I recently drove it on a hard 1200-mile drive with absolutely no issues.

Thanks in advance, everyone. If more details about the problems are required for better diagnosis, let me know and I'll call my father for extra information (since I wasn't there at the time of said problems).

Check to see if the ELD is functioning properly. I had to install a bypass.

What is ELD?

it does sound like the vss.

you can spray silicone in the window run channels and see if that helps, but it might be the window regulator going bad. later.

or battery and/or alternator going bad..

#1 - happens to me twice..check for the vss's cable / connectors..probably one of the wires leaked and touches the body..secure with electrical tape / heat shrink tubes..

#2 - did the same as TypeG..

ive eprsonally seen a lot of vss failure on accords. dont be worried.

rear windows arent used as much so they usually fail prematurely. you should excercise them regularly.

[Nurega]

Thanks for everyone's input.

#1: I'll try securing the VSS and see if the problem happens again. If it does happen again, I'll replace it.

#2: I'll try TypeG's spray-silicone method, and if it still fails, replace the window regulator.
What are the window-run channels, if you don't mind me asking?

i recommend ebay for a new vss. i got one from 'chandlermotorsportsinc' for about $20.. works perfect a year later. at the time there were lots of CB7s losing their vss.

As weird as it may sound, I say this^ is whats going bad. Happened to me during the summer, First gauges, then windows, then...car died.

the run channels are the rubber seals that the window glides up and down on. later.

If the odometer and/or cruise control work, then it is not the VSS.

I'll do this soon. Thank you, Brian.

So it could be the alternator failing, not the VSS? I'll talk it over with my mechanic and see which option is most likely. Thanks, everyone.

So what was the end result from this situation? I am having the same problem now. First my speedo, then windows started rolling up slower and sometime not all the way. maybe 1/2 way. And what type of silicone spray did u use?

Thanks for the info

I won't be able to work on my car until the 18th. My father borrowed it and kept it for the month. I'll post the results when I get my car back.
