Question about 2001 Dodge Grand Caravan
Yes you are ru=ight about cold solder joints. as you might be handy working on cars youcan try to fix it yourself, But if your not handy with tools andintricate things you best leave this work to those that are. Remove the instrument cluster, leavingthe wiresconnected. turn the key on and push on the electrtrical connecteras you watch the gauges that are/nt working. If the serial bus weren't makig a connection then the check engine light would beon, or is it? Wigh the key off disconnect the electrical connector and the pins that plug in I scrach them by pulling lightly on the with treaded needle nosed pliers slipping off till they are all a little ruoghted up. Reconnect and try again. Sometimes afterhavingthe cluster disconnected ou may needto disconnect the battery sothe ECM will look for the cluster again. This is a common problem but ther's many varaitions of reconnecting including using a true scanner to cycle the gauges in an output test.

I had the same problem with a dead instrument cluster. No tach,speed, temp,or gas reading. I removed the cluster and found that the solder where the main connector attaches to had a faulty ground cracked solder, I resold erred it and reinstalled it, it is now working fine. There are very instructive videos on YouTube to guide you. Good Luch! German Garcia( Miami, Florida)
