Im trying to replace the blower motor switch on my 1993 190e .,.

i took the two screws off under the wood panel..

i see the two screws on the bottom of the center vents too..

do i need to remove those screws to get to that blower switch.. i also see the two screws that hold the switch in place.. do i need to remove the entire push button assembly to replace the blower switch?? if so if anyone has done ths before i sure would appreciate
any ideas in how to get that switch and or unit out

thanks in advance@@
