Ok, had all the linkages off the other day adjusting valves and the arm out of the servo (thing that pulls the linkages to do the cruise control) is just limp. I don't remember if it's supposed to be that way or not, anyone know?

And no, my cruise doesn't work and something looks fried in the amp... I'm wondering if this could have caused it.

I believe the servo is limp when it is not activated. It is possible that a bad servo caused the cruise amp to fry but from what I understand it's not very common. If you get a new amp it wouldn't hurt to get the servo checked too.

ok, thanks, that's what i needed to know. I'm going to try replacing the fried component on the amp if I can find it.... I don't want to fry it again because something else is bad too.

If that doesn't work, try some Viagra. I understand that after amp surgery it is sometimes necessary.

I've got no interest here except as a consumer but you may want to check out these guys. If you ask them to they will test your servo and amp units and give an estimate. They rebuilt my amp and servo about 4 years ago and I've had no problems since. There are some good pages on this website to answer common questions about both the Cruise and Climate Control electronics. Good luck.
