I need to pick some brains regarding an odd intermittent problem.
I have a 1993 Dodge Grand Caravan SE with a 3.3 L engine. Everything
works excellently except for the speedometer and tachometer "freezing"
at random intervals. On a perfectly smooth road [no bumps appear to be
a trigger] the speedo and tach will both stop right in their tracks
and stay stuck at whatever speed/rpm I was traveling at the moment,
even if I speed up or come to a complete stop. The odometer will also
stop dead too. The other gauges appear to keep working fine. If I stop
then shut the key off, the speedo and tach will then drop to 0. Upon
an immediate restart, they usually will remain at 0 no matter what I
do. Then, while driving for a few minutes, they will suddenly start
working just fine. At that point the power door locks will realize
that I am moving and will lock the doors, as they are supposed to.
Sometimes, the speedo/tach will "freeze" for a few minutes then
suddenly start working as I am driving, without me stopping or
shutting off the key.
This does not happen often but often enough to be a concern, about
once or twice a week. Today, however, it happened twice within a 15
minute span. Hitting any bumps in the road makes no difference one way
I would really like to fix this problem, as the van is in almost mint
condition otherwise and I would live to keep it for a while.
Any help would be greatly appreciated.
