I'm looking for a little help on diagnosing a cruise control. It doesn't work :-) I have vaccum to the diaphram and signal from my interior controls. I checked for power as well, so no burnt fuses or bad wiring. This means, correct me if I'm wrong, that the two electronic boxes behind the dash must be the culprit. Has anybody been here before? Can parts store diagnose the boxes if I pull them? How easy are they to get to...ie what else is going to have to come off to get to them? Thanks for the help -Jerod
