fixing cruise control

[Alienwrkshp6866]

How do you go about fixing the cruise control on a 2g? I searched and all I got was about how to remove it. Can someone help?

Start by making sure that it's plugged in and that the cruise control cable is still connected to the box on the firewall near the throttle body.

I do not have the vacuum diagrams for the cruise control. I looked in my chiltons and it wasnt in there. Dose anyone know how the vacuum lines hook up for the cruise control. Im almost possitive thats what the problem is.

As far as I know, the cruise control system does not use any vacuum lines. The cables that Andy is referring to are mechanical cables which allow the ECU to adjust the throttle plate. The cruise control box has three cables going to/from it: One is connected to the accelerator pedal, a second is connected to the cruise control actuator (which is what the ECU controls), and the third is connected to the throttle body (to adjust the position of the throttle plate). The cruise control box is purely mechanical and allows the ECU to adjust throttle plate position when cruise control is enabled. Hope this helps!

EDIT: There is one short vacuum line which runs between the actuator and the auto-cruise vacuum pump (black cylinder just below the actuator). The actuator is located at the passenger-side of the engine bay.

I see the short vacume line to the vacuum pump , but the pump has two other nipples that look to have had vacuum lines connected to them at one time. I guess I can try to loosen the black box from when I messed with doing the free mod to make sure I get wot.

What's wrong w/your Cruise control anyways?

I lost my cruise control when I blew my radio fuse...

My cruise was working until i put in a new uicp. Now it wanted to stop working. I dont know whats wrong with it. I drive over an hour and a half a day on the interstate and I wish I had cruise.

Does your radio work?

Mine didn't... didn't think too much of it cause I didn't use it tooooo much. Bothered me more when the cruise control didn't work. Try checkin all the fuses?

Yea well this is a daily commute to work and back and its annoying without it. Dose anyone have a picture of all the parts to the cruise system under the hood? That would help allot. I'm looking at it blind trying to figure out where the vacuum lines go.

Try this? It's a visual tour of a 2g engine bay.
