Up until about a month ago my CC worked just fine on my 93 Accord (220K miles). Now when I press the button it appears to have no power. I have checked the fuses and the vaccum lines, everything appears to be in order. I have read a little on replacing the main relay but wanted to put it out there for suggestions.

Thanks,

You say no power. Does that mean the cruise control main switch does not lite when you press the switch? or what? If the light works there is power going to the unit. How about the brake light pedal switch? Clutch switch (manual transmission), set/resume switch on the steering wheel, the cruise control unit? Things to check. Main relay wouldn't have any effect on the cruise control. But it would keep the car and fuel pump from running.
