Truely.

And, after I poked aruond on mbworld, the question of tire sizes came up. Are yours OEM, or have you changed the sizes?

For interest see the following site which states your comments as true.

After more thought I think a brake related problem can be discounted and I would focus on the speed control switch and the wires and contacts from it. The PCM being presumably OK, hopefully.

You guys rock. Thank you SO MUCH for helping me out with this. You are leaps & bounds smarter than me!!

Failure of this spring would allow the pedal to drop and imitate the pedal movement that switches off the speed control, that would be a doubtful reason though, but who knows.
As the speed control switch appears to accellerate the car, I would think that what is stopping the system from setting the speed is something to do with a signal that says the brakes are in use, the minimum speed has not been reached, or that the car is in park. Is there something amiss at the throttle body motor which presumably is the component that holds the speed? I shall keep looking, but I can see it is a real puzzle.

Funny story though. I was putting my intercooler back on my SRT4 one day. The IC was sitting in the garage for months. I didn't even think to look in it. I spent 11 hours putting the car back to stock. IC was last component. I even test drove it after I did everything except the IC. Worked great. So I swapped the IC at 10:30 at night (had to work at 7am the next day). I tried to start it at 11:30pm and bam. stalled immediately. Wouldn't stay started. Had to get a rental car for the next work day and have the car towed to the dealership. I'm sitting talking to the sales guy about a new car and the service tech comes up to me with a dirty packing peanut in his hand. It hit me before he even said something. "Any idea how this got wedged into the throttle body's idle motor?" "Uhhhh... Nope! Must have sucked it in while driving!" "You mean you sucked it THROUGH THE AIR FILTER!!?? Gee! How'd ya do that!?" Yeah, I looked like an idiot.

Re: Cruise Control won't turn on!!
OK, looking through these last few posts, I might rule out the throttle position motor as it seems to work OK when driving normally.
The MB forum suggests that if the front/rear rolling ratios are off, it might exite/confuse the traction control which, for safety/obvious reasons will disengage or prevent the cruise control from working.
Do you still have the OEM tires and wheels to put back on for a test?
Just a thought...

I'm having an issue with the cruise control. Am I correct to assume that all you need to do to turn on cruise control is either move the lever up or down to SET it at the speed you're currently at? I did that, and it never SET. When I moved the lever UP to the ACCEL/SET position, and you could feel the car try to speed up (ACCEL). But it never locked in the speed.
The only thing I can think of is that I currently have my winter wheels/tires on which don't have pressure monitors. So technically the car thinks it has 4 flat tires, right?
Anybody seen this before? I have seen it work before, but havent' tried it in months. Any help would be greatly appreciated. Thanks!

The cruise lever does go up for accel set, and down to decrease and set. Now look at the very top and it says off. With or without the key on pull the lever toward you. Now try your cruise control again. I pulled the lever 2 or 3 times mine works fine now. I'm a dummy but it works. Good luck and let me know. 2005 C F Ken

Re: Cruise Control won't turn on!!
I don't know if you have fixed your cruise control issue or not. I have a 2004 Crossfire and I finally fixed mine today. I feel kind of stupid, but it was simple.
