Cruise Control Poll
I've picked up in recent months we forum members have ongoing problems with cruise control in our C3s...I'm curious how bad it really is. If you've got cruise control and wish to participate...please do so

Re: Cruise Control Poll (hunt4cleanair)
I tore mine out. The one time I inadvertently pushed the button, the car started accelerating like a bat out of heck! And where exactly am I supposed to put my right foot if it isn't pressing the accelator anyway? :smash:

I use a brick :lol: :lolg: seriously though those late 70's type cruise controls never did seem to work properly even when new, they solved the problem with the computers, throttle position sensors, etc.

Re: Cruise Control Poll (hunt4cleanair)
I installed an aftermarket cruise control in my 73. I love it. :thumbs:

Re: Cruise Control Poll (hunt4cleanair)
I have cruise control. It works sort of, so I clicked on the have cruise but does not work choice.
I get my car up to speed and push the button. I can feel the cruise take control of the gas pedal. It will stay at speed for about 10 seconds, then it gradually slows down. Uphill or downhill. The thing I have noticed is that if I touch the pedal, it will go back to preset speed, and the whole ordeal starts over again. Sometimes, however, if I touch the pedal, it will speed up and keep speeding up.
Think a new transducer will help?

I've got it but it didn't work when I bought the car in October 2002. I really love cruise so it will be another project for me. :cheers:

Mine works fine. Of course, if it doesn't, the speedometer is usually going nuts so I have to replace it. However, next time it dies I'm going to pull it and swap in a '84 Vette cruise control unit instead. (You have to have all the EFI stuff to do it though.)

Should fix & a new lower speedo cable may be needed as well.
Wait, I don't currently have cruise, nevertheless expect you will find the above accurate.

Re: Cruise Control Poll (hunt4cleanair)
My '77 never came with cruise. Over the past six months I was able to find all the NOS parts to install it. $700 later I now have the $88 option. I learned a lot about how they work and it is not rocket science. Trouble shooting them is a pretty simple task. If your speedometer works you know the cables are fine. If your brake lights do not come on within a half inch of pedal travel then the cruise circuit probably has an open circuit. This setting is critical. The same goes for the vacuum switch which is mounted above the combo brake/cruise switch on the brake pedal. If the vacuum switch is set too far out then you have a constant vacuum leak. You can test the servo by applying a vacuum to the line going to it. If all those test out then the problem may be in the transducer. The most frequent problem with these are dirt in the vacuum venturi. The venturi is the brass vacuum fitting on the right side. Do NOT take the venturi tube out as you will damage it. Just blow it out with an air hose. The dirt is generated from the wear on the spinning magnetic disc. If you have to pop the side off the transducer just note the position of the cover so that it goes back in the same position on reassembly. Once again the reason most cruises stop working is because of the improper position of the switches on the brake pedal. That is the very first check you should make.

Re: Cruise Control Poll ('79ProwlerOrange)
2 vettes- '93 and '77- neither cruise control worked. It's okay, I don't want to use them anyway. I prefer to keep my foot on the pedal where it belongs!

Re: Cruise Control Poll (Captain_Kaboom)
Mine works pretty good (wood :smash: ). Just recently took a 30 mile interstate drive each way and used the cruise the whole way. The only problem that I have is that I have to press the cruise button around 2-3 mph lower than the speed I want because when the cruise engages, the car speeds up 2-4 mph. During the 30 ride the speed slowly increased around 4-5 mph over the 30 miles. SO, I guess mine works pretty well. Can it be adjusted to not speed up or is that normal.?

2. If car cruises below engagement speed, screw orifice tube outward.
3. If car cruises above engagement speed, screw orifice tube inward.
Note: Each 1/4 turn of the orifice tube will change cruise speed approximately one mph. Snug up locknut after each adjustment. The orfice tube is the brass vacuum fitting on the right side of the transducer. The lock nut is 7/16 and the fitting is 3/8.
