I just purchased an 89 C4 and drove it back from its old home 650 miles. Great fun and great car except several
Central Information warning lights while cruizing displaying the Interlock light and brake light. Pulling over and
restarting would take care of it for up to 150 miles but it would come back. Obviously I have a problem. All seemed
well except for the lights. I will take it in soon. Any ideas? Brake fluid is full.
Thanks for any help. I have had 2 other earlier 911's and no "brains" to worry about..
