I have a 98 Lexus GS300 and earlier this year the fan/blower stayed on high regardless of the speed the blower was on. Well today the blower or fan is not blowing; the heat/ ac seems to work because I hear a clicking sound when I change the fan level or the temperature...do anyone know about this and what I should have replaced? On a fixed budget need all the free advice on this I can get. Thanks, Lexus driver
