Hello. It sounds like you have a voltage issue. When the power in the vehicle drops below a certain level these lights will come on as a warning. Since they come on when turning on the blower that means that the blower is drawing just enough power to cause a drop which is turning these other warning lights on. It may be due to a failing battery, alternator or maybe a bad connection. These would all have to be tested to find the issue. If you are going to have this electrical issue checked, consider YourMechanic, as a certified mechanic can come to you to [diagnose why the abs and brake lights are coming on] https://www.yourmechanic.com/services/abs-light-is-on-inspection
