Okay this may sound stupid at first but it has me alittle dumb founded.

On my 03 SXT Caravan, i swapped my cluster with a tach model, Well it works just fine besides some idiot lights being on as mine doesn't have ABS etc but i expected that, well anyways the problem is afew of the cluster lights don't work, You have the 3 in the speedo, 3x tach, and the other gauges, well there was 1 in the speedo and tach that wasn't working so i thought burned out bulb so i went to change them out and still got nothing out the bulb so then i was thinking bad socket well i swapped one from a good working location in the cluster to a non-working location and it worked fine but any new light i try to install or out my old cluster doesn't work and it has me rather confused.. Anyone run into this before?
