Hi,
Well things have been pretty good here in 1998 K3500 land! Until today, that is.
I noticed one of my rear tires low, so I refilled it and went to take a shower and came back and it had gone all the way flat! I guess it was time for new tires anyway. So I jacked up the rear end from underneath the middle of the rear differential, and changed out the tire for my spare. No problem. Well, the jack let off a bit fast while I was lowering it, but no real problem.
Then I went to drive and discovered that my speedometer doesn't work! I only drove a few blocks, and never above 30 or so, so I don't know if the shifting was doing anything weird. It didn't feel like it.
In carcode, I don't see any relevant codes (security code that I cleared from when I last jump started the truck, and some random misfire codes during warm up, but nothing VSS related.)
I know very little about carcode, though, and might just not be looking in the right place.
Well, for that matter I know very little about the VSS either. My only guess is that the jolt from the jack letting the back end down quickly dislodged a wire or something? I hope so!
But where to start looking? Any thoughts are much appreciated. I'm going to start digging into this more in the morning.
Thanks!
