My 2000 Eldorado is having HVAC issues. When I call for A/C, the driver's side does so but the passenger's side generates heat. When I call for heat, the driver's side does so but the passenger's side generates cold. Took it to a local dealer yesterday (4/4/22) and after a few diagnostics it turns out the passenger actuator is toast. Part has been ordered and will be installed tomorrow. I was told by the service advisor that I will receive a Senior discount...yahoo! The Eldo is 22 years old with only 80K miles on it.
