Just bought a used actuator and blower motor. Still have clicking noise. Also, still see the two yellow lights blink(in air circulation and ac) when I push the button for the in cabin air circulation. I have a 1998 Volvo S70. Any ideas what else could be wrong? Thanks!

 

You might just need to have the codes cleared.

 

Is the only way to clear the codes is to go to the dealership?

 

most likely.
