Question about 1999 Subaru Legacy
I finally fixed mine, on my 1999 Subaru legacy 30th anniv edition. . .
I removed the speedometer head, and resoldered the green connector on the board. Then I also ran a wire to duplicate the trace wire from the middle pin to the first connect (about 4mm). Problem gone.

I had the same problem on a 99 Legacy. The protonspring's solution worked for me beautifully. It's now been probably at least 4 or 5 weeks since I've applied the fix and so far it's been working! In fact, I did a little more than protonspring suggested. I couldn't see anything wrong with the solder joints under the microscope but I retouched most of them anyways, and I added a redundant wire jumper from the pin 3 of the connector to the next via as well. On the top of that I cleaned all the connectors and lugs on the speedometer head PCB with plenty of contact cleaner. I did the same with the connector plug attached to the sensor wire before installing the cluster back in place. That connector feels a little loose and I wonder if that was the whole problem... I took some pictures while doing this job...

I had the same problem and was about to get a new speed sensor at a Subaru dealer when the mechanic talked me out of it. He said I might as well throw the speed sensor on the floor because that won't solve the problem. He told me he has seen it before and it is a wire that leads to the speedometer that is a little loose and needs to be resoldered to the circuit board. He gave me the # to a speedometer repair shop in my area where Subaru sends their speedometers. I took it over there, he pulled out the instrument cluster resoldered the wire and put it back in for $220. If I pulled the cluster out myself he would have charged me $150. It now works fine.

I also had a 1999 Legacy wagon with a non functioning speedometer. The fix above by in the post by protonspring worked like a charm. I soldered two jumpers, one from pin three to it's contact point and a second from the ground to it's contact. Works perfectly

I think the issue is just with the screws that hold the speedometer to the circuit board. I just cleaned them with steel wool, then used bulb grease to keep the contacts working. (I think the screws are aluminum, so they lose contact over time.) Also cleaned the other contact points that those screws bring together. So far so good.

This link is very good. I just bought a 1999 outback. Are there any tips on removing the instrument cluster itself?

I had this problem and i read some things on here about how to connect the middle pin to the first one or how to connect the middle pin the SP. those could work but when i tried the first one it made my speedo work good witch is what i wanted but when i went over 50 the odometer would go plus 5 miles for ever real mile. so i ended up just heating up the old sadder on the 5 pins and now it works fine. Hope this helps out a little.

I had this problem 2 years ago I had a 1999 subaru legacy sus 30th ani. We tried to things with the car which was check the wiring which wasn't too great but also wasn't the problem. The problem is the speedo head. The cars do have this problem and I have talked to other people about this and read into it. What you need to do is replace the speedo head unit. it is pricy about 250-300 at any mechanic (besides subaru) I highly recommend buying a brand new speedo head! Do not buy used! hope this helps you all. Like I said this happened 2 years ago and hasn't acted up since It was at 110000 miles when it happened and I replaced it at 118500. Right not my car is at 156000 so you should be all set with this.

I have a Subaru 99 Outback and the speedo (and odometer) started to work intermittently after it came back from the shop (for fixing oil leaks). Then at one point my battery went dead and I replaced the battery. The Speedo worked just fine for about a day after that... Not sure what to do and I don't want to spend a bunch of cash on something that won't work.... Any one come up with a good solution?

I have had the speedometer out, there is no cable, just a wire so we can at least eliminate that possibility

Ok I had this problem on my 95 legacy. I replaced the speed sensor and the problem went away.
it didn't cost too much and it's a unscrew old one and screw in new one type deal.
I would suggest buying the hanynes manual if you need help putting it in.

I soldered a new wire, and the speedo worked for a couple thousand miles, then intermittently again. I may just reflow all solder points.

Fixed it too!
I had the same issues except my cruise wouldn't engage either. Speedo was crazy and worked sparingly if I used the power windows, but not always.
On the back of the Speedo head I noticed that the blue GROUND plug was loose in the connector. So instead of paper I took a toothpick and broke it off in the connector/wire area and another one between the the two connectors. WORKS GREAT!! BTW I checked all the solder joints and had no cracking or oxidation, fortunately.
Thanks for all those for their input!

I have a 1995 Legacy L AWD and recently I too lost my speedometer function. I replaced the speed sensor and it still does not work. My question is will the above wiring repairs work on my cluster as well since it is a 1995?
