Need help with my cruise control help?

[Redwookie]

Ok so I know just about zero when it comes to cruise control but I do know that mine is not working correctly. Some help from you fellas that know this stuff would be great! So the cruise control sort of works here is what it is doing: When I try to set the cruise control it will set about ten mph after I hit the set button. ie. I hit set at 75mph and it catches around 65mph. It was holding that for a while but now it seems to just slowly lose speed. Slower than it would if the cruise wasn't working at all though. Any ideas where to start? Thanks guys

Hope you've got a faster internet connection than I do (now), the factory diagnosis should be some of the "pictures" here:

1990/91 may reference the DRAC, however on the prior ones, back to about 1982 or so, the DRAC functions were handled by the VSS buffer, hanging off the back of your speedometer. Only three wires needed, power, ground, and signal. I wouldn't worry about it yet, since your cruise partially works.

Hope the manual pages help.

Thanks Dorian. The manual pages should come in handy for diag.!
