Cruise Vacuum Component Locations
Slowing working through the list of to dos on my '93 vette. The next item on the list is the cruise control. I found that I have no vacuum at the servo or the source that feeds the vacuum tank/servo. I checked the source at the tee and no vacuum. The service manual shows that the line goes to a check valve then on to the source. Can anyone tell me where the check valve is located and where on the engine is the source? My manual does not have this data being a preliminary version.
After this, then on to the headlight followed by the antenna.

There's a tee/check valve that's located under the passenger side fuel injector cover. I deteriorates from the heat. Also, if the vacuum release switch (works off the break pedal) is misadjusted you'll have the same condition.

Re: Cruise Vacuum Component Locations (sraft)
Thanks for the info. Finally had time to check out the valve. The valve was shot. Replaced it for $3.88 and the cruise control now works. Cheap repair.
