my motor....

I'm hoping to have my Certs all by the time I finish school and get a job. I'd like to do some more work on the car but the repairs are catching up to me since I just don't have the money.:( The list of things needing to be repaired or replaced is
AC Compressor
Wiper Motor ( If I ever find out what is wrong.)
Replace the passenger side wiper arm, it cracked while I was putting it back on
New Battery (I've found out it's almost dead)
Muffler (welds broke off around the pipe)
I'd also like to replace the speakers since I lost my factory ones and toasted the pioneer ones. I was kind of hoping to do some mods to the engine (possibly pacesetter headers since I would be doing exhaust work anyway) but that might now have to wait another year.
