My CC on an 99 300Ce works intermitantly. Checked the contacts on the 14 prong connector on the amp and seems good. Any other suggestions?

The curise control amp most likely needs to be resoldered.

I had given up on mine ('86 420SEL); I changed the timing chain this spring, got it all back together (whew!) and, It's a Miracle! my cruise works perfectly.
Guess I jarred something or made contact when I took the actuator off to get it out of the way. Who knows? sometimes we get lucky.

Try this link. I had a similar problem. The GDL website is good cause it shows you how to test all the cruise parts. Before I went through the tests on the gdl website I actually called the guy, described the issue, and they virtually assured me it was the amp. Told me not to even bother testing the other stuff. Popped in a used amp and problem solved. You can get them used for $50 bucks shipped from www.europeanautomotivegroup.com. That's the lowest price I found on the internet and they give you a 30 day guarantee. The first one surged a bit and they were real good about sending me another one. That one is working great.
