You can get white lithium grease spray.

The center port may be best as the double "piston" tries to seal center to bottom & center to top.

Another thing I forgot to mention is while silicone is rubber safe, some silicone sprays actually use a rubber-attacking propellant. One way to check is to spray it on a styrofoam cup. If it eats away the cup, then don't spray it on any rubber.

the 3in1 brand silicone spray



is safe


CRC brand ...



is not

I have used the white lithium grease in tube for many years on the rubber vac. AC/VENT/HEAT switches in several cars as well as reg. etc.

I wasn't sure what part needed to be sprayed, so I sparayed silicone on several moving parts, thinking "what could it hurt?" Both lights immediately stopped working. I just started laughing. My luck is so bad I could fall in a barrel of ***** and come out sucking my thumb.

Hey Ganey,

on tha pic you posted, are you spraying the lube in the square hole on the end or one of the vacuum hose ports?

I have a light that is sticking from time to time and getting lazy. I haven't started looking at it yet but I need to....sux at a cruise in and one light doesn't open without dicking around with it.

To spray I suggest the center vac. hose port.

After having removed the passenger side actuator, I have decided there is no spray for a seal that fell out in pieces.... The rebuild is under way for both. Slowly but surely I am making this car new again, one piece at a time.
