Ok, this will help understand how this thing works.
I took this image from the steering lock thread. What you see here is our IPDM. The ONLY relay that's removable is the black one, that's the starter relay.
Inside this beige board are many more. (wiper, fog, a/c, etc.) But i've not been able to find any pictures of what it looks like inside there. I'm a bit reluctant to crack mine open to see if it looks like we can replace one or even clean them. Most of the ones you have to solder as typically fragile and you risk breaking them if you try to open them.
