I have done a search on here but have not found the answer that I was looking for yet, so I am coming to you guys for help. My cruise control was working until I done a plenum fix. The green cruise light wont come on or anything. Everything else is working properly as it should. Is there some kind of electrical connector or something that I may have left unplugged that would cause it not to work? Is there a fuse or relay that is just for the cruise that may have blown when I put the battery back in and hooked it up? Thanks in advance for any help yall may have for me...

 

not sure if this helps much, or you already knew this. I dont know much about the relays and such, but your cruise control module is the little can looking thing underneath the battery. So if you removed your battery when doing the plenum, make sure you didnt drop it back down and cut a wire or anything below it. I dont really know without going outside to check on my truck if there's sensors in it or not, but i guess i'd assume theres at least one wire to it, besides the vacuum hoses.

 

Even if the cruise module got borked doing the intake, the cruise should still power up when you hit the on/off button.

Check fuses.... maybe you trashed one.

 

I pushed the cruise button on the steering wheel today and the green cruise light came on this time but still no cruise control. I am assuming I messed up a vacuum line at some point during the change. I think I got them all hooked up but I will have to see if I cracked the plastic one that goes from the intake to the servo. I pulled it across and back out of the way so it probably broke somewhere in the plastic sleeve. I will check it out real good tomorrow and let yall know what I find. Thanks for the input guys.

 

Well here is an update!! I checked the line out and indeed it was broke. I put a new line on it and still no cruise control. I started looking around and found that there was a vac line unplugged on the fire wall. It was a green air line with a funny looking end. I plugged it up and hoped that would work and nothing. The green light still comes on and all. I am gonna pull the battery tray off tomorrow and check under there.

 

Uncap that green vacuum line. That is the vent line for your front axle engagement.

 

What plugs on that nipple that comes out of the firewall that is about the size for a vac line to plug to?

 

I don't think its a plug, I think its a filter......

 

Ok! There is a end sticking out of the firewall on the driver side like something is supposed to be plugged onto it but I dont know what goes there. Any idea?

 

Drivers side? Can you post a pic?
