Default Which switch?

Our host’s catalog G36 on page 172 shows various blower switches for a/c and non a/c cars. The only switch shown for 66-67 is M157H with no indication if it is for a/c or non a/c. Was there only one switch used in 66-67? Need the correct switch for my 66 with a/c. Is the one in these pics correct?

Pretty much had to be different. My A/C 67 GTO had 4 speeds on the fan switch with the bottom position being Low. My non-A/C 67 GTO has a 3 speed fan and bottom position is Off.

I am pretty sure it is the same switch.

Had one of each in my hands when I was restoring car.

Non AC car just didn't have any connection to bottom position, which only function was to control blower motor. Three speeds on blower.

AC car had a switch on upper lever of control panel that turned off all power by controlling a Master relay on firewall. Four speeds on blower.

However, your photo does not look like the switch on my 67. Here is mine;

Here is a burnt out switch that came from my 67 with air. Make sure all your connections are good and snug. I burned up two switches and blew several fuses all because the connection on top of the air box behind the glove box was loose and caused an over heating problem in the rest of the A/C system. Once I secured that connection I had no more problems.
