Hello All,

Repost:
I was hoping that someone could tell me how to test the "Cruise Control Pedal Switch". I have the switch out and it looks fairly simple. But is it as simple that when the plunger is fully engaged that I should have a completed circuit.

Thanks in advance,

In a '98 (going on your signature here, I'm a bit confused - which do you have?), the cruise control switch is the one with a vacuum hose attached to it over the brake light switch, which i believe is the one you have removed.

Sorry for not posting more details. You are correct this ride is my 1998 S70. The switch is the one with the vacuum line, above the brake light switch. The cruise has not worked for some time, so I stuck my hand up around the brake pedal and I could feel the switch was loose, I could easily move it. Once removed I could see both of the plastic tabs (facing to the outside) broken. So my thought is that if the switch is functional I will try using couple of tie-wraps to hold in place.

The electrical pins will have 0 ohms or continuity depressed and infinite/open released. The vaccum port is sealed depressed and vented when released.

Maybe the plastic tabs are to keep the switch secure. If you tie wrap it up there you'll probably have to get it pretty close to the proper position and you'll have to reset the plunger. With the switch installed, press the brake pedal down, pull the plunger out (you should feel a click) then let go of the brake pedal. This ensures that the switch is 'made' when the brake pedal is at home position.
