ToddMic Posted September 3, 2010 Share Posted September 3, 2010 I'm having a problem with my Lexus - been a great car for the past 5 years so I can't complain. Last week, when I would turn on the car and the fan would turn on for 4 minutes and then shut off all together. Now, the fan won't turn on at all. For the air conditioning, everything else turns on but the fan. Any ideas? Quote Link to comment Share on other sites More sharing options...

There is also quite a bit of info at the following link.

There is a 1999 RX 300 manual at http://us.lexusownersclub.com/forums/index.php?showtopic=52026 that could be helpful for troubleshooting. You might start by searching "blower motor control relay" (include the quotes) to get an idea where to start. Good luck! Quote Link to comment Share on other sites More sharing options...
