Guest PontiacDude210 Posted July 28, 2014 Share Posted July 28, 2014 I just took a 240 mile round trip in my 1990 coupe and I decided it is time to get the cruise working. I have just replaced all the vacuum lines I can find, and I don't even get the dash light on when I click the stalk to ON. I have b672 and b673. Those would be the cruise control vacuum faults. No function when I pull up on the brake either. Do I replace the servo, or is there something I could have missed? Link to comment Share on other sites More sharing options...
raleets Posted July 28, 2014 Share Posted July 28, 2014 My CC on the '89 coupe (115K at the time) quit last summer. After carefully checking out all the vac lines, I bit it and ordered a servo from the Reatta store. Installation was easy and it immediately fixed the CC. It's worked smooth as silk since.Good luck,Bob Link to comment Share on other sites More sharing options...
Guest Mc_Reatta Posted July 28, 2014 Share Posted July 28, 2014 You do need a new servo. Can find new or used easily enough. Link to comment Share on other sites More sharing options...
