2001 Mercury Marquis AC/heater blower and stereo

I want to thank you for your time, first there is an intermittent problem with the blower makes no different if it is in auto or set to AC heater etc. The Blower will come on then shut off and it does no matter what setting it is on. It does not even work if you manually adjust the blower speed. I also have an issue with the stereo it will come on but no sound, not being a auto expert I am guess it is the amp blew a fuse, not if there is one or if there is where it is located. I would greatly appreciate any assistance that you could help me with. Again thank you God bless and have a merry Christmas and a happy new year.
