Location fuse cigarette lighter fuse

Heater fan, electric mirrors and electrical outlet (cigarette lighter) do not come on/work at all. I think all fuses are checked but any advice could be helpful and is much appreciated.

I have a 2003 Dodge Grand Caravan with 71,000 miles. My stereo and cigarette lighter quit working. The digital clock will still display if you push the time button on the stereo. I am hoping it is a blown fuse. I took the cover off the IPM Fuse & Relay Center and all the fuses look good. There are several larger black fuses that don't really look like fuses. The fuse diagram does not list one for the stereo, so I am just wondering if you know which one it is or if you know what it would be called? Maybe the accessory relay? If so, how do you change this one? It is one of the larger black things that doesn't look like a fuse. Does it just pull out or do I have to take it in to the dealership? Help! Thanks !

Radio, Clock and Power outlets just stopped working. I replaced the accessories relay and no change. Hoping it is just something simple so I won't have to take it in for repair.
