Headlight Problem
My 75 coupe is acting very strange when I shut off the car the right headlight will rise all by itself along with the left side,they take turns.
I then have to start the car for them to drop. I have new headlight actuators installed.Any help much apprecdiated.

check valve located in the vac line right on top of the intake manifold.
It's supposed to be a one-way valve, when it begins to leak/goes south the headlights will pop-up as will the wiper door either upon engine shutdown or sometimes when you floor it.

I know I got one just like it from Corvette-101.com.The port closest to the **** (#2)is the main vac source from the manifold.The other port(#3)goes to the pulldown.Here is one from a 69 that is correct at the switch.
