Alright, if you haven't gotten it removed yet, you can do the following. This method came back to me from my old Pontiac days., but nt until after I had already tried the old needle-nosed plies :/
If you have access to compressed air, use an air nozzle with a rubber tip and place it into the port where the hose manifold bolted up (RH Upper), it's the one with the small opening into the compressor. Use your thumb, or if you have someone to help - there thumb to plug off the LH Lower side - this is after you have installed the blak plug/ & snap ring into the port you were able to remove the other switch from. Clean around the switch very good to remive any crud if you haven't already, and make sure the snap ring is removed. Place a rag over the switch to pad against it when you apply pressure (it may take a couple of long applies, and you may have to push the switch back down a time or two, but the air will push the switch up & out.
Note: Be very careful when doing this, as the switch will become a projectile if not controlled/caught in rag. Wear a pair of safety glasses too - you only get one set of eyes.
Still cheaper than buying replacement
...and thanks for the P/N's
