Speedo not working

Hello, I'm new here, just bought a 00 Ford Ranger, 2WD, pretty standard. The speedometer does not work at all, no Odometer advancement so its not working period. The Speedometer light is also not on. Any suggestions to this problem? I have checked fuses with not luck, local Ford Dealer says new $600 speedometer, I want to be sure before letting them abuse me. THanks

so none of the lights come on at night??

since the speedos are all electronic, try checking all of the connections on the back.

and if you need a speedo, check ebay.. they are like 40-50 bux

Check to be sure that all of the plug connectors are on the back of the cluster. You may have a total loss of power and/or ground to the cluster if the lights also don't work. It could be the cluster itself but check the easiest stuff first.

I just sold my old speedo on ebay for close to 50 bucks. If you need a new one, ebay is going to be your best bet.

It's your ABS sensor located in the center of the rearend housin..........$20 + tax at your local Ford Dealer..............should be a PN# F85Z-2L373-AC and it takes 5 minutes to install yourself.

Did one on my Son's 99 Ranger 3 weeks ago with same problem.

That's what I thought of first for the inoperative speedo. What stopped me was the fact that he also has no lights in his cluster. Of course, he might have two unrelated problems. ABS/VSS bad and all bulbs burned out perhaps.

My truck did that when i cut the black tabs off my dome light and shorted something out. then my speedo,wipers,interior light and a few other things didn't work and it was just a fuse. But hey I'm not an expert it's just a thought.

OK it turns out the Cluster does not have total loss of power, it does light up at night, there is also a ABS warning light on. Does this still sound like a ABS sensor or should I get try a new cluster. For $20 it is worth a try, can you reach with your hand?

Thanks to all who replied, I am going to buy a used cluster on ebay, Does anyone know if I can upgrade to one that has a tach on it? The one in the truck now does not have a tach so not sure if buying one with a tach and speedo combo will work.

Thanks

If your cluster has power, the speedometer doesn't work and you have an ABS light, then the ABS sensor on the rear axle is probably bad. 98~2000 Rangers use that sensor for ring gear RPM to the ABS and for the VSS signal to the speedometer. It is not difficult to replace.

Do your know the part number/name and where to look to take it off and replace it? I will try this before replacing the cluster. Thanks for your relply.

The Ford dealer has the P/N. It's right on top of the rear differential housing and costs about $20 or so. Easy to unplug, unbolt and replace.

BUMP

Ok, tried the ABS sensor, did not work, bought a used speedo cluster on ebay, Has anyone swapped theirs out and any tips before I dive into switching the two? I think I can handle it with some advise from you all.

You will need to pull the radio and its bezel, then the knee bolster panel under the column. With that stuff out of the way, you can remove several screws that retain the instrument cluster surround. Remove it while unplugging the headlight and dimmer switches. Then you can unscrew and remove the cluster itself as you release the 3 electrical connectors.

Still not working, replaced the ABS sensor on the rear axel, replaced the speedo cluster today and the ODO and Speedometer still dont work, everything else works.

I hate to bring the truck to the theives (local Ford Dealer), they are the ones that assured me before I needed a new $500.00 speed cluster, I've had other issues with them in the past and even took them to court once, and won for a major screw up.

Any other suggestions? Is there a speed sensor somewhere, I've heard on the Crown Vic theres one under the dash that goes bad.

Thanks

Check the large connector under the truck located directly below the driver's seat. It joins the main interior harness to the rear harness and the speed signal passes through it. Use a socket to remove the central bolt from that connector, then open it up and check for water/corrosion inside.

No, 98~2000 have the speed sensor on the rear axle.

Checked the connection out, Corroded bad, numerous male prongs corroded off into the female side, so you were right! Now, do you know if a person can order just the connections or need all new wire harnesses? Also do I need to take the seat out to get at the top connection?

Thanks again for your help.

Yes, you will need to pull the seat and lift the carpet.

The pins may be available somewhere but I don't know where. Motorcraft may sell a connector repair kit but I couldn't find one in the catalog. You may possibly be able to order one through a Ford parts department. Be prepared for sticker shock, though - Motorcraft repair connectors are not cheap.

That connector is infamous for collecting water and it was finally eliminated in 2004 when the harnesses were revised and rerouted. I have my connector packed with dilectric compound in the hope that it will prevent the corrosion. This is a good idea for any 2003-back Ranger in any environment but especially if you wheel in wet/muddy conditions.

What is this dilectric compound and where could someone get some of it?
