Hey guys, I just wanted to say hi, I have been reading this forum for some time now and really enjoy the information and experience’s you guys share with each other. I have been registered for a while but could never seem to get logged on. It seems the problem is with my zone alarm fire wall…when I have it running I cannot get logged in, when I turn it off I can get right in…anyone else with this problem?
I have recently purchased a 1977 Tan Corvette and as soon as I get it back together I will try and get a picture of it on this forum. As of now it runs good, just got it to pass inspection (New Jersey) and I am finding out all the different ways I can spend money on this car.
I am currently trying to get the heater/defroster/vent control to work, it seems it is controlled by vacuum, as far as I can tell I have no vacuum getting to the control switch and one of the lines appears to be missing. To make matters worse (things with this car are always worse) my driver side vent is missing, (this would be the vent by the kick panel) I am guessing that the car was in an accident and it just didn’t get replaced. If anyone has worked on these vacuum lines and can offer any advice I would appreciate it. Thanks
Welcome. Congrats on the 77, a very good choice of years. See my website 77 Facts.

The problem is that heater is the default position (no vac. or vac. leak) due to being designed in the north. Vent should be default. Very safe bet the problem is 1 OR 2:
1) The vac. line from engine is damaged from heat - a small plastic tube that goes in below the hood theft switch into wiper valley. Replacing most of engine side w/ hose will fix. OR
2) The vac. switch itself is not switching due to vac. leak as the usually plastic rivet is not holding the 2 main switch parts together well. Besides replacing, it is also possible to tighten this &/or lube w/ white lithium grease or vasoline to fix.
3) If you have a heater, the hose underhood probably also needs replacing. Block w/o heater.
PS The design problem comment is not intended to be offensive to any of our northern friends. :cool:

I replaced the one on my '78. The line that was on it actually looked like a white electrical wire. Searched and could not find the tube. NAPA recommended, and I used, air shock tubing. It worked fine but, I am keeping an eye on it to make sure it is not heat affected.
If you don't already have it, get a copy of the AIM (Assembly Instruction Manual). It has diagrams of how everything should go together, is available form any Corvette Vendors (Zip, Mid-Aermica, Corvette Central, Ecklers, etc) and is only about $25 with the index.
Well I found out what the problem was, I will be getting a copy of that AIM guide asap. I was thinking this was a vent that would provide a little floor circulation. This car is hot as hell even when I have the tops off…I though the floor vents were not working…I guess this car doesn’t have floor vents…I finally got this vent to open when I put the AC switch to the max position. This must the recycle vent to put cabin air back to the AC. Oh what fun! Thanks for your suggestions…I took everything apart and cleaned it, the switch has plenty of vacuum now. Can anyone tell me how to post a picture?
Welcome Paul! It's great to build up our ranks of small block C3's. We've been losing some of the small block members of our C3 forum lately to a highly contagious and frequently terminal illness. Alas, poor Bence, he was such a good kid. :nopity
Hey Paul, we're neighbors! I just moved from Hopatcong to Roxbury last year. Welcome to the forum.
If you're not already planning to attend, think about driving up to the Ramapo College Corvette show on June 9th. Lots of guys from the forum will be there.
welcome paul,congrats on getting it through new jersey inspection thats the biggest thing so far its all downhill from here. :yesnod: theres plenty of mods to do on a vette.
welcome aboard Paul- Heck move to South Florida and you can cap off those fresh air vents and run the A/C 24/7/365. No emmisions testing either. A corvette hevean. Just kidding- welcome aboard. Now for the real advice- forget about the vent and install a cam.
