Do you also have a vacuum hissing noise on the light switch when you turn it on?
or is it definitely defective?
Should not hiss. I would check the hoses that attach to the valve in the switch first. If the are not leaking then you have a problem with the switch. Hope this helps.
Tom,
There are at least 12 different places that noise can be coming from. However, if you can hear it while inside the car and not outside, I would suspect the headlight switch has a hose that has split. Easy fix. Same with all the other hoses.
Do he doors open and close ok?
Is one slower than the other?
Thank you!
I'm currently putting it together. The lamp motors only run when I switch the valve.
Based on your expertise, I suspect that a hose on the light switch is leaking or the light switch itself is defective.
An easy way to check out any vacuum operated system for leaks is with a smoke machine. You can plug (or T it) it into any hose in the system, turn on the smoke, the entire system gets pressurized, and the leak (or leaks) shows up quickly. It produces less than 1 PSI, so nothing gets hurt. Most auto repair shops have one, so if you have any problems finding your leak, it can easily be checked.
I would pull the switch-should take about 5 minutes. You'll be way ahead by removing the left.
Thanks, I'll report back
I applied light air pressure to the line and it got lost at the switch. I installed a new one, thanks
So is it fixed?
Yes it works good. would like to load up a small video. but how? :)
