Odometer and Speedometer Not working-99 Windstar

russcheri · 07-15-2009, 08:43 AM

I am having a problem with my odometer and speedometer gauges not working. I have checked my fuses, put in a new #10 fuse, but yet it still does not work. Am I replacing the right fuse? The owner's manual wasn't too clear on which fuse works those gauges. Please help????

There is no simple answer for us folks outside the group of Ford electrical designers. That is a close-knit society ... who don't want us to know very much. I'll share what I THINK.

I would take a voltmeter and check the tops of all fuses in both boxes ... at the battery and inside the cabin near driver's left foot. You may or may not find any problem with fuses.

The "output shaft speed sensor" on the tranny feeds info to the PCM. The PCM communicates directly with the speedometer/odometer thru the "twisted pair". (I think).

russcheri, my speedometer was only reading half speed and the cruise was not working either. I replaced the speed sensor on the tranny and the brake pressure switch under master cylinder, neither solved the problem.It ended up being a bad abs wheel sensor on the drivers side.

abs wheel sensor on the drivers side. hmm.

maybe that,s what is wrong with mine.

i have the same prob. checked the fuses,

so far none blown or close.

no error codes at all, might be the other fusebox under the dash,

the abs light & brake light is on,

I have a VSS, (Vehicle Speed Sensor) fault code. I hear its not that hard to replace but I cant seem to find it on the tranny. Does anyone know its location? My speedometer is off as much as 10 mph at 60 mph. It reads slow. Cruise Control is not working and when I slow down for a red light the trans shifts down and then back up in a jerking motion.

Are these problems that a bad VSS would cause? Thanx

Thanks to BroncoJoe19 for the tranny pix. I don't know if my 3.8 has the same tranny as in your pix, but I'll look to see if the vss is as shown in the pix. Do you know how to determine what tranny one has?
