Speedometer Not Working

[utkayaker]

Neither speedo works (digital or analog). I have read there could be a connection with the ABS and with the speed sensors at each wheel. I found some specs on check for resistance through the speed sensors and they seemed fine. It may be important to note the ABS light on the dash is always on. It may also be connected to another problem I have - the spoiler doesn't go down (one time it went down but it seems frozen in the up/extended position).

Any ideas?

Is there a central ABS controller that could be the culprit?

Thanks!!!
