Pull the radio and check to see if the fuse in the back of the radio itself is blown. There is a small clear-plastic carrier that pulls straight out from the back of the radio with the fuse in it. Be careful pulling out the plastic carrier. They can be brittle and easily break. Replacement fuses can be sourced at Radio Shack.

Good luck Alex
