yesterday my car was driving fine. I drove it home in a bunch of snow.
it kept snowing. today i leave fo work and my speedometer was jumping all over the place -- everything else was working fine tho. while idling it was going up and down fairly quick. several hours later im on my lunch break, still not working. Could ice have been on it, melted, and maybe got the contacts wet? did it just up and die? Other gauges are working fine and dash lights come on so its not a fuse. Any help appreciated -------------------- QUOTE (Azncelica @ Mar 4, 2012 - 11:43 PM)  I started with what I know to do, I swap engine into my car, I knew it was too much work to make it a AWD. I kept it FWD. Went to take a crack at doing the wiring conversion. Than, I realize, shoot, this is out of my league. |

Speedo sensor is probably dead, they're plastic and will eventually give out.

Seems more like an electrical problem -------------------- QUOTE (Azncelica @ Mar 4, 2012 - 11:43 PM) I started with what I know to do, I swap engine into my car, I knew it was too much work to make it a AWD.

Then again the internals of the sensor could cause the electrical problems

The gear slipping would. Not sure why the gauge would arbitrarily stop working without recent tampering, but it's possible too.

Also, i understand what you meant by the gear slipping -- but how would that happen while the car is parked? The diff wouldn't be moving at all -------------------- QUOTE (Azncelica @ Mar 4, 2012 - 11:43 PM) I started with what I know to do, I swap engine into my car, I knew it was too much work to make it a AWD.

I didn't see that. Being it's electronic and not mechanical it could be.
