First - Power door locks dont work.
Second - Horn doesnt work.

I have a haynes manual but it doesnt say anything about them both. I've looked online but couldn't find anything. Any suggestions? Thanks in advance.

 

1) fuse...switch...relay - check with tester i.e. "fluke"
2) fuse....horn button....horn itself...again check with "fluke" or equivelent

 

Could you give any info on the p/lock relay? Color? Location? Thanks

 

for the horn check the relay. If not the cheapest and most effective option is to get an air horn. You can get one at AutoZone mad cheap.

 

generic universal horns are like $10

 

horn is probably a blown fuse
and here is a link to fix the power locks its a really easy fix and will save you 80 bucks
