Steve2150 Posted March 20, 2013 Share Posted March 20, 2013 1990, when I try to put on cruise control the light on the dash only lights up when you push the button to accellerate, lights up but no cruise, any idea what must be fixed or replaced.

Ronnie Posted March 20, 2013 Share Posted March 20, 2013 I assume you have checked the fuses and vacuum lines to be sure they are in good condition. Here are instructions the check the cruise servo:Cruise Control Servo Electrical Testing - Reatta Owners Journal Link to comment Share on other sites More sharing options...
Guest Mc_Reatta Posted March 20, 2013 Share Posted March 20, 2013 Use diagnostics to pull trouble codes. Several cruise electrical problems will set them. Vacuum problems don't. Link to comment Share on other sites More sharing options...
Guest Richard D Posted March 21, 2013 Share Posted March 21, 2013 I found out that most of the electronics are mounted in the throttle servo. I had a similar problem and Padgett sent me one and all is well. GM used the same servo in 100,000s of cars. It took only about 10 minutes to swap out. Try Jim Finn or Marck for one. Maybe Ronnie has new ones. Link to comment Share on other sites More sharing options...
