2003 Saab 9-3 repair Question radio

u need a radio amp ,this amp is located under your drivers seat ,this amp has a fiberoptic wire going through it which inturn makes all those components u listed work ,u may have gotted the amp wet at some time ,or it just failed .so get a price from your dealer or check goldwing saab.com they will ship anywhere ,note used part for saabs only that is all they sell .good luck.

ho also note that the radio head unit can cause the same iissues too ,to check all this take radio out & unplug connector from back ,now check if u can see a red laser light in the connector if u can then the amp is ok u can also do this at the amp under the seat too check for red light ,do this & post back & i can tell u for sure which component is bad .
