I'm working on fixing my headlights and have a question for y'all. When I pull the headlight switch I get the sound of rushing air. What could cause this?

Early on I had the same problem, the over ride switch had a crack in it where the previous owner jammed a golf tee into one of the ends....I guess he was too cheap to fix the vac line or buy a 10 cent vac cap......LMAO!!!!

Just a thought, what condition is your dash in and your speakers? 
 
The reason for asking is there is a lot of things that go on under the dash that can be fixed eaier if the dash is out. 
 
Do not pull it unless you indent to replace it as it most likely will not take the bending with out cracking it takes to get it out.  But if it is cracked and you plan on replacing it make there is lot of thinks that become easier to do.

I see in the pic that the headlights are up..do they ever go down...if not start looking for the leaks..sounds like the leak is somewhere after the switch but I wouldn't say its the only one..

If the leak is at the light assy... rebuilding the headlight assemblies is not a bad job and not tooo expensive for the kit.... Will make a hell of a difference too.
 Good article below for that
