QuestionI have a 1990 Cutless Supreme Euro edition quad 4. the problem is with the ventilation system. It is stuck in the defrost mode. It will not go to the bi-level or floor mode. What is the cuase of this problem? |
ReplyPossible causes are that the vacuum hose for the vent is not connected or the vacuum switch in the dash is defective.Angelo Silverado Auto Service |
