gas gauge only works when engine is cool

did this happen at the same time or has one failed, then the other??

the fuel gauge could be a bad connection at the sender or dash unit. the locks could be a failed module or grounding issue.

They fail at the same time

I just hit the power lock switch and the dome lights came on. The locks make a little noise like they are not getting enough power.

Strange things are happening. I pulled the 40 amp fuse to the door locks and the ac compressor engaged. Both radiator fans are not working now .

the 40 amp fuse is for the fans.
door locks have a 15 amp fuse
you have some sort of wierdness going on with control systems. diaged it here is impossible without seeing and touching it. you need a good electrical shop that can track down these types of problems.
one problem area is under the battery. the harness melts from battery acid fumes and cuses opens and shorts. thats the only lead i can give you at this time.

I wiggled a couple of wire harnesses and everything came back. I just don't know what I did.

I would look at the bottom of the barrey tray for the harness issue. it is very time consuming and a lot of patience is needed.

Roy

when it starts acting up I'll check the harness under the battery. Thank You very much

good luck

this problem with the door locks and gas gauge happens alot on other dodge cars. Is there any way I can hook up a fused 12 volt wire to by pass the power lead to the power locks?
