Hello!
First thanks for The Bathtub Admiral for giving me the suggestion to check around the PCB for all the solder joints for this problem. Before I start to do that, anyone has any other ideas on my car problem so that I can try to do them together when I take the car apart? Thanks a lot.
Intrepid 97, 130K miles.
Problems:
1) windshield wiper starts as soon as I start the car, will not stop. 2) the interior lights do not work. 3) Gas and speed meters (sometimes other meters join the party too) on the cluster panel seem funny and shake around even the car stays still on ground. 4) Power door locks do not work. (power window work) 5) The sound from engine sounds like running not stable (sometimes faster, sometimes slower). 6) If I drive it, some kind of "choking" sound from the below of the car, and the car drives like hitting a rock every several seconds. 7) If I take off the BCM and start the car, the meters on the cluster panel have no readings, and all other problem exist.Have checked:
1) multi function switch and the headlights switch, seem OK. (all problems still exist even if I take these two off). 2) changed the BCM (got one from junk yard), all problems still exist. 3) all fuses seem OK. I also tried to switch the relays in the power box to see if anything will happen, seems no difference. 4) I checked the battery and its grounding, seems OK.A small painfull video is here if you like to have a look (each about

So, any other suggestions?
Thanks a lot and have a great weekend.
