So I drove up to wisconsin this week and my cruise started acting up real bad. When I set it it would surge real hard and then back off and so on...... and then after a while it didnt work at all. So I checked the vacume line and replaced it with a new one. Still does the same thing.
Also anyone have the wiring Diagram for the cruise modual.

Thanks again.

Which line did you replace? I replaced all my vacuum lines with silicone hose and it solved my cruise and vent issues. I'd continue lookin' into your vac lines just to be sure.

The controller should be under your drivers side battery, there is a line running off of that to a "T" fitting that runs down toward the lift pumps direction. It continues towards the firewall. There are several more "T's" that run to various places and there is a line running across the engine, this is the typical culprit because the turbo heat tends to cause it to crack, all these lines are plastic and get brittle. I replaced all mine with silicone hose and I've had no problems so far.
