I gather that the car sat for a while, meaning the problem could be multiple vacuum components for the heads light. I recomment looking into electric conversion. for less than 200 you can eliminate the vacuum all together. PM me.

Are your headlights raising and lowering?

go to Wilcox and down load their head light drawing. it will help with all of your questions.

Light wont come up at all can i use a conpressor and try to push air into canister would that make healight go up

No! Most of the time if the headlights won't come up it's because the 'seal' (grommet) is leaking and needs to be replaced.

Here's another trouble shooting guide.
