Electrical problem

My 98 Durango's panel lights go on and off, when this happens the blower goes on and off too along with the automatic door locks and cigerette lighters, seems to go on and off if I hit bumps I know it's a loose connection somewhere just don't know where.All help will be appreciated

If you don't know where too start, then you will have to start from scratch. Tracing wires with a ohm/volt meter.

Sounds like a loose connection at the fuse box inside the cabin or maybe one of the other main connectors under the dash on the left side. Before breaking out the ohm meter, you should go under there and start wiggling wire harnesses and connectors to see if you can make it happen.

It could also be a power feed from under the hood, so if you don't find anything under the dash, start wiggling things under the hood between the power distribution center and the firewall.

when that happened to me, it was the main power wire going to the fusebox under the hood.

Sounds like a connection to the BCM, this controls all these functions. I'd also check the ground between dash and battery, you should have little or zero ohms for a good connection

My Durango had a gremlin of a problem like this...Look on the passenger side in the kick panel area and up behind the dash for ground bonding points. I had one that was loose and it caused all kinds of havoc. My heat/ac would work sometimes, doorlocks worked when they wanted to, and one time I shut the truck off and it continued to run with the radio on. Other times the radio would remain on until I shut the door and I guess the shock of the door closing broke/made contact to shut the circuit off. Theres another couple of bonding points behind the driver side dash/instrument cluster area that you could check too. Good luck!
