The CC amp is right above your feet. Just unclip/screw the panal and you will see it.


Resoldering the amp is pretty pointless. I pulled mine apart, the connections can be tested with a meter. Don't see how they would break.

More likely then not you will need a rebuilt amp, about $200 a company called GDI does them. I don't have the website handy.

I suspect the circut card gets messed up somehow on these.

Thanks.
I looked up there and didn't see a little box. (what's it look like? )
Cruise works fine sometimes, jerks at others and kicks back in when least expected...I thought a faulty connection.
$200...sounds like I'll be using foot cruise control...as I never get to go on any long trips...doesn't stop me from setting up my cars and bikes like I go 'touring' all the time!

Did you remove the panal under the dash? The CC amp has a big plug sitting on top of it and is held to the firewall on a metal bracket? Block box says Bosch and some other stuff on it.

Thanks!
One of the threads I read said it was a metal box so I didn't look for anything black.

It's an aluminum box on a black bracket attached to the brake pedal attaching
bracket.

Cool I was looking for that link. My next project is sending my CC amp off to them for a rebuild.

People have found that tightening the linkage can stop the "surging". You might want to try that first.

Could you elaborate a little more on "tightening"? All my linkage moves nice and tightly with no play that I can detect but I do have some surging so I guess I've got some adjusting to do.

(Thanks Pat!)

It seems to lie in the last linkage rod in the chain that connects to the cruise actuator.

It's not that they break, they "go cold" after years of just conducting electricity in dirty environments.

I used to get cold solder joints on my main frame (telecom) all the time....you just heat it and let it get cool again...just like new after that and ready for 25 more years.

Lot cheaper than $200, as long as you are careful and don't cause problems with the PCB or components. Use a heat shrink on anything near where you are soldering, if possible.

I'm doing mine soon...I have one of those new soldering pens that get cold in seconds..

I tested mine with a meter, they all conducted real nice.

I also resoldered mine in 45 minutes and it worked great.
