My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
The blinking light generally indicates a fault has been detected with the heater/ac system.What will need to be done here is to have the fault codes checked with a scan tool that can read all computers in your vehicle to see what codes are set.Once this has been done the codes can then be diagnosed to properly locate and correct the fault.
The system may just need re calibrated after the servo was replaced or repaired to correct this here.
Thanks Pete
