Need a better description of the problem.
If you describe the face of the radio, I can suggest some fixes. There is one model of cassette player and one model of cd player, both built by Chrysler that have microprocessors built by North American Philips, (NAP), the same people who build the really crappy Magnavox and Sylvania tvs that I worked on for 35 years! These microprocessors have a 100 percent failure rate. I have the equipment to replace them, but then the software must be burned in. They will never sell me the equipment to do that. These radios have three tone controls with yellow leds. The cassette player is model number 56038518. All I can remember of the cd player is the model number ends in a "67".
There is a long list of common problems, but the most common ones are the yellow leds flash on and off with a thumping sound in the speakers, and no display, or, the radio goes dead momentarily when moving the volume or tone controls. It is not cost effective to send these radios in for repair, but there are other models made by Mitsubishi for Chrysler cars that are very reliable. There's a direct replacement for the cassette player that looks exactly the same, has the same three lighted tone controls, and will run the same remote cd changer if you have one. The only noticeable difference is it has one extra button for "Scan". These sell for more than 70 bucks on eBay because used car dealers all over the country are looking for them for their used cars.
If you have the Chrysler-built cd player, I'd recommend upgrading to a cd / cassette combo. These are also built by Mitsubishi and give very little trouble. There are cd-only units but most of them are built by Alpine. Alpine is the only company that will not allow the authorized service centers to sell me parts or service manuals. I can still fix them, but I don't promote products for companies that pull this selfish nonsense.
Some of the other common problem are intermittent FM, intermittent AM and FM, and intermittent display, but these problems usually occurred on older 1990s radios. Once these problems are fixed, they're usually fixed for life, meaning they won't occur again.
If you have access to another radio, install it and see if it does the same thing. If it does, suspect a loose fuse in the fuse holder. This is not common in Durangos, but is very common in '96 and newer Caravans.
If just the sound quits, but the display and push buttons still work, suspect something related to a remote-mounted amplifier or its fuse. If only the display goes out but you still have sound, that's a radio problem and usually not too difficult to repair. It just takes a long time to take it apart to get to the problem.
If you can pull the radio out far enough to find the model number on top, holler back with the number and a list of symptoms and I can give you a better idea of what it will take to fix it.
