To be more specific. Yes, you have a problem that cannot be fixed by just replacing fuse.
Fuses blow because:
1) Some lame ass previous owner fogot to connect all grounds to factory connections. See also anyone else who failed to document disassembly steps and does not work on vehicles 24/7.
2) Do not feel bad if this is you; we have all been there at some point. Consider it a paid lesson in automotive education. It is how you move on that counts.
3) Become thoroughly famaliar with the use of a muti-meter. This is the last thing most techs learn. Learn it now and reap the benefits.
