Re: is this bad?

i didn't know i had cruise control (just got the truck a couple of weeks ago)...where is the switch? i've got a button at the very end of my turn signal lever, could that be it?
 
Re: is this bad?

yeh thats it, also there should be a for lack of a better term, slide lever lookin thing on the end, and words like off, on, set/resume my words are worn off but are shiny so u can see em still at the right angle. My cruise dont work i gotta fix it, but those are the controls.
 
Re: is this bad?

Not on a '76. They use the old style, just a button on the end of the turnsignal lever. I know they changed it sometime between 1980-85, just don't remember the exact year.
 
Re: is this bad?

so i take it the pics are of the cruise control? i'll hook it back up and see if she works (hope the engine don't blow-up!)

thanks guys
 
Re: is this bad?

thats right, /forums/images/icons/crazy.gif , i 4get they didnt use the same one all the time. Losing my mind as we speak lol
 
Re: is this bad?

Uh I sorry they used Both type switches on 76.........76 was the year that had split year parts. I have a 76 now and have had 3 others all had different styles of cruise control switches. Thats the facts Jack!

Cruise. My 79 has the same set up. Press the button once to set it. Press it and hold it and it's Acel quick tap and it's off. If you had set it then hit the brakes it shuts off. It you tap the button then it's Resume.
There is a couple switches on the brake peddle. One is the cruise and one is the brake lights. thos switches often get screwed up with age. Check those for age. The way it's wired the switch is pressed when your foot is off the brakes. If the switch is not pressed then the cruise will not engage. That was what was wrong with my 79 when I got it. once I fixed that it has worked great.
If your on the hwy and you come to a stop after using the cruise. Get going about 30 MPH and hit the resume button that sucker will hit passing gear and punch it up to speed. Freaked me out the first time I did that. Though the throttle stuck and hit the brakes and it stopped. LOL hit it again and sure enough as soon as it got back up to speed it took it easy.
 
Just took a good close look at the second picture. The other thing with the vacume hoses comming out of it is the Crusise control speed pick up. Looks the the Cable is off it. The speedo cable routing will be from tranny to that modual then a second cable runs up to the speedometer. If the speedometer works then at some point a cable broke or the Cruise contorl modual locked up and it was by passed with a speedometer cable from a non cuise equipped truck.
Look in your glove box and there should be a build sticker that shows all the options the truck came with.
 
hey grim,
i found it interesting your info on the cruise control. i recently purchased the complete (or so i was told) cruise control kit (used) to put in my blazer which doesnt have cc. is there any way you could email me detailed pics of your complete system and tell me more about the break pedal switches. im not sure i have those, or is it just a wire to plug in ? ive kept all info related to this subject pertaining to our vehicles year i have come across on ck5. any help is greatly appreciated. thanks.
 
Is the setup you bought from the same year as your truck? You sound like you aren't sure what year it is, and if its electric ('85 up?) it will be totally different from a '79.
 
nope,nope. its not newer. its a 78' and is the same. i just have to buy a new push button wand. just need to know exactly where everything goes and how everything works and relates to each other. thanks.
 
Re: is this bad?

I've never seen seen the new style on something that old that wasn't swapped in. My '80 and my old '78 both had only the button in the end of the stalk. Maybe the one with the big end was an option?
