Default Speedometer not working

Hi, I'm new to the forum and my first car is a 94 Nissan hardbody xe-v6 and it's a 5 speed.

My problem is my speedometer used to bounce around around 50 degrees outside temp and when the engine gets warmed up it would be fine.

Now, I was driving with cruise and heard a click, the cruise light flashed and then shut off and the speedometer is now stuck on 0
I took it to get the vss tested and that was working fine which limits the problem to the instrument cluster

Any help and advice on what to do?

Speedo head may have gone out. Unfortunately it is a very common problem. Many of us V-6 guys are plagued with non-working or temperature-sensitive speedometers. There's not really a good fix for it other than buying a new instrument cluster and hoping you get a few years of use out of it before it goes bad as well.

Yea, I'm not super good with electronics so I was told that speedometer issues were common and the best bet it to get a replacement and hope it works or get mine rebuilt. Do you have any suggestions or know what the exact cause normally is?

The older rigs are far far more finicky. Probably just the receiving end for your speedo. Best bet might just be to grab a dash from a truck in a junk yard and replace your speedo with that one and hope it works. The older mechanical ones need voodoo magic to work properly once they have had a problem.

Mine is one of the older voodoo magic ones Deerhurst is referring to. I don't have any experience first-hand with the newer ones, so I can't really offer much in-depth advice. Just going off what other guys here have mentioned in the past.

V6 clusters are fairly hard to come by though

If it was cable driven I would say it snapped.

The problem with these clusters is that the plastic is getting dry and brittle, causing it to get a little smaller. That lets the screws holding the electrical tape down get loose and the electrical connections to fail.

You could pull yours off and go through it like the guy below did. He did a very thorough job, but really just taking most of the screws off and wiping the connections down should go a long ways.

On the other hand, there could be a small electrical amplifier or capacitor on that wiring cluster that went out. If that's the case, no amount of cleaning is going to help it.

Thanks, so I've called every cluster repair place and Nissan dealers and no one will touch them because of the problems and age. I'm looking at full after market swaps and just build a new panel, or get a junkyard cluster and hope it doesn't happen again. First I will try the cleaning method and check the screws and I heard about a gear that can snap or strip so I'll look into that too. Thanks for the advice

There are Sellers on eBay that offer to repair instrument clusters.

Nobody lists a Hardbody cluster because there are not many of those around, and the ones that are around are generally old and the owners don't care.

Try sending one of these Sellers a message to see if they would be willing to try a repair on what you have.

autoxpress_axt
ezelectronics201
gmspeedometerrepair
irebuildit
jamesrogers_2000

Those sellers all repair Nissan instrument clusters, so one of them should be willing to go over yours.

FYI: Their fee will probably be in the $100 range.

Thanks again! I will definetly contact them. My goal is to keep the truck mostly original because it was a my great uncles and has sentimental value, but obviously if I need I will hit up a junkyard.
