On my wifes 2000 durango, the rear wiper, radio, and the dome light quit working. Fuse or is there a relay some where that controls it? The fuses look good, not saying they are. Thanks.

Do a continuity check on the fuses? Or call Decker!

I don't think there's a relay for any of that stuff, so definitely check the fuse with a meter, or swap with a good known fuse to troubleshoot.

all the relays are for things like the transmission, fuel pump, ASD circuit, head lights, horn, etc. I don't think any of the intnernal accessories like the radio, overhead domes, etc use relays. the heater blower motors MIGHT, but I'd have to check the diagrams again.

There is a relay for the wiper in the Power Distribution Center under the hood. The wiper relay is next to Joint Connector no 1 and is by itself. There are twelve relay sockets (3 rows of 4) next to Joint connector 3 and the 13th one by itself is the rear window wiper relay. Not all sockets have relays in them.
In the Junction Block next to the driver side A pillar two fuses run the radio. Fuse 18 is switched 12V from Start/Run. Fuse 3 is from the battery. Either one will kill the radio.
I would check the fuses first.

Here is a thought if the dome light and radio stay on after the key is turned off then it's being controlled by a relay or control module, i had one one go bad on a 2001 cady that was doing the same thing.

Just my two

Most likely you have 2 seperate problems? the dome lights and radio is probably a fuse,could be on the same circuit. The rear wiper should not. The wiper will be ignition power, while the dome light should be battery constant power and the radio needs a battery constant power also. most likely related. Are you sure the rear wiper went out at the same time?maybe just didn't notice it before?
