I have a 1999 Grand Caravan that suddenly started having a problem with the fuel gauge and the power locks. The gauge will randomly drop out with the fuel light coming on and chiming. Sometimes it will bounce right back up and repeat randomly other times it will stay down. At the same time that this started happening the door lock switches also stopped functioning. The locks also randomly start and stop functioning usually along with the gauge, but the problems sometimes happen at different times. Any help would be appreciated in solving this issue, have been driving myself nuts trying to figure it out.

Ck the fuses in the PDC for the IOD fuse,that would be the top fuse. Make sure its push in all the way.If that doesn't fix the problem. you may have codes in the BCM. Or in the cluster.
