ford focu 03.. luggage release switch & remote switch don't work?

hi, i have an 03 ford focus. today i replaced the fuse for my rear wiper as it kept blowing the fuse and failing. in the process i removed water that had managed to get into the reversing light unit, which i suspect may have been why the wipers kept fusing. anyhow, since doing this the luggage release switch on the dashboard and the key fob don't open the boot although it did work twice after completing the original job. i have searched through the owners handbook to see if/where the fuse is located for the luggage release switch but there is no listing for it, not even as a shared fuse.
could it be a fuse that has caused this problem too or something else? i thought i may have dislodged a wire when removing the reversing light unit but looking at it now, the only wire there is the wire to the light unit.
please help, it's driving me crazy.

guess i got used to the laziness of switches instead of the old fashioned way of using the key to open things. i would like to know how to fix this and if i may have inadvertently caused it.

what gets me is the boot was functioning after all the work i did and then suddenly stopped!
