Help with Relay switch housing (corroded)

Hello gentz, basically on the driver side fuse panel under the hood i had a relay switch go oout, well as i was pulling them to test one of them which is a 4 prong switch only had 1 prong, 3 other 3 pins broke off in corrosion into the housing.
So, i am wondering how i can fix this, i got a new switch, i just gotta figure out how to get the corroded ones out. Can i take a tiny drill bit and drill down from the top or drill up from the bottom and be golden? Then maybe spray some electrical spraqy in there or something.
Any hints are much appreciated as i am about to head out to do the brakes id like to get all this done in one shot. The switch that is corroded is the abs relay. So far no big deal but i do got 2 brake lights on in the instrument panel.

Thanks again.

i would get a spray that helps loosen and disolve corrosion, and try thin needle nose pliers or something from the top, you drill em you are going to ruin the part inside. Be sure to disconect the battery first

This is not uncommon. The UEC is not protected on its underside, and may be subject to corrosion.

If you cannot remove the contacts with pliers, you can disconnect the battery, remove the UEC, and push the contacts out from the underside:
