Final video about the HVAC system I repaired on my C3, 1978 Corvette. In this video I discuss a custom solenoid bracket I made to kick up the idle on my engine for use with the AC compressor. A bit of a challenge to get this all done but I'm about finished with this project.

What did that bracket come off of? I want to purchase one, I have a 4150 double pumper with the same aluminum throttle cable bracket setup as yours, i have the same issue you were having with the ac.

Hi, I just started researching this very same problem with my Holly carb, and I not only amazed myself for getting this far, but finding your video really opened my eyes. I must admit I envy your way of doing things in a tidy manner. Thx again.

Great video, but where did you pull the signal wire from on the AC for the solenoid it’s self? I have the Edelbrock AVS2 with Edelbrock intake. Running a thumper cam. When I originally did the cam I had the stock intake and Quadra jet carb. The throttle kickdown stayed energized after key was turned on, setting the idle by when I turned ac on it would drop. I never had this issue prior to pulling the engine for the cam work. Thought I was getting air through the intake so I swapped everything. I’m ideling at 850 without ac and it drops to 500-550 with ac. It’s driving me nuts.

I use the feed to the AC clutch before all the pressure switches. This way the idle will be kicked up as long as you have the AC turned on. The AC clutch may turn off and on but the idle will stay up. If the AC is off the solenoid will drop out. this way if the clutch turns off and back on the idle will already be kicked up. Sometimes the solenoids are not strong enough to kick up if your at idle.

I know this video is somewhat old, I have this issue with mine, bought 2 Holly brackets and neither will work with the holly carb I'm using for the idle compensator for my A/C .. this is an awesome remedy.. If you don't mind what is the part number of the Jegs kick down bracket you are using on this engine.. thanks !

Looks like you have a beautiful car there.I have a 78 vette, but living here in CA. We have some tough smog laws. So we are very limited On what we can do with our cars.Which is practically nothing. What is that rod with the heim joints connecting the upper control arms?

Hi, Thanks for the comment! The rod you see in the video is a spreader bar to stiffen the upper frame and "A" arm mounts. Made by Vette Brakes and Products and goes with the high performance suspension I have on my car. The bar only works with electric cooling fans. You cannot use it with an engine driven fan.

Really Nice work. Your engine has a very similar layout than mine. Do you happen to have the item number for the bracket you ended up using? Keep up the good work.

Thanks for the nice comment!! I ended up making the bracket in the video. I couldn't use the Holley brackets because the QFT is a little different and because of the throttle linkage I'm using.

Nice clean engine but the only thing I saw was you covered up your emergency hood latch access with the vacuum reservoir

I just viewed your video on the C3 AC project that involved the Idle Compensation Solenoid. If possible I'd like to have a conversation with you as I am having difficulty getting the AC in my '75 to work well. I hope to hear from you.

Nice work on this engine! I have to step up my wiring game it seems... Quick question: it appears as if you have the Quick Fuel 49-148QFT solenoid? Does the solenoid housing spin after the nut has been tightened to the bracket? Mine does this, and it just doesn't seem right... Beautiful job on your car man!

Solenoid is a Holley 46-74. Solenoid would not normally turn in the bracket because it is a "D" hole. My bracket that I made is a round hole so it just goes in and the nut tightens up to prevent rotation. Thanks for the nice comment. I appreciate!!!
