Title: New to Corvette
Post by: stuclark on May 18, 2014, 06:47:35 PM: Sorry, I have been trying to find some posts relating to 2 issues I am having.

I have only just got my first rebuild/ restore/ US car. '79 C3. 2 issues, Horns sounding constantly, something not right with horn switch on steering wheel, any pointers please, is there a repair kit you can get? Also idle is very rough. I have vacuum lines disconnected and blocked and one from under the air cleaner that has broken off. It is small diameter and have white plastic joiner snapped off inside. I have searched and searched and cannot find where it goes/ comes from, but seems to have little to no vacuum when you cover with your finger. Does anyone have a diagram of the vacuum plumbing or Emissions systems for stock '79 C3 350? Only had the car a week and sorting the obvious stuff first... Appreciate any help :huh:

Could also be the lower horn ring grounding out the column - http://willcoxcorvette.com/product_info.php?products_id=24018 (http://willcoxcorvette.com/product_info.php?products_id=24018)

Post by: stuclark on May 19, 2014, 06:42:47 PM: thanks for the replies, both have pointed me in the direction I need to go. Looks like I need to get the steering wheel off to see lower section. BTW, on the link for Jim Shea's he talks of a host website to download images of steering columns etc. Does anyone know the host website?

My location is Western Sydney near St Clair.

Post by: Vettech on May 19, 2014, 07:06:04 PM: Is the horn constant or pulsing on / off - if on /off then it's the on board factory alarm, remember this was originally switched on the left door. If constant then the steering column - use the web or a Builders Book - I like these as they give great exploded diagrams - well worth the dollars if you are looking for originality and want to be buried in the car.
The next club meet is at the brekky this weekend - I can bring it along it's for 78, but should be relevent for 79.
