Where is the main computer located? The fan controls erratic
What is your question?
Air always works but thru defrost only. Stops/starts without warning. Date on computer unavailable, three dashes where temp shows. This is so erratic and frustrating
RepairPal Certified shops can diagnose and repair your 1999 Oldsmobile Aurora. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
The air door actuators are controlled by the HVAC programmer. The programmer is located under the dash on the passenger side behind glove box. I would recommend having diagnostic's performed.
