Jarebear Posted February 18, 2016 Posted February 18, 2016 I have a problem with my blower motor on my 98 LS400. I noticed that, intermittently, the blower motor will kick down from the speed its at to a very low speed mode. Eventually while I'm driving, it will kick back up to the speed its supposed to be at. When it kicks down, it usually only lasts a few seconds and then goes back up. Anybody have any idea what might be causing this. I've already seen some discussion on this issue, where some suggest it might be a in-car phone wiring issue. I really don't think this car had any dealer installed phone, but I'm not 100%. There are no left over components from a phone that usually accompanies an old car phone installation. Is there any chance this might be a blower motor resister issue? I replaced my blower motor a couple years ago, but not the resister. Let me know your thoughts.
jamesm182 Posted February 19, 2016 Posted February 19, 2016 There is a common fault with the LS400 regarding the blower motor not changing speeds - not sure if this is linked with your issue but may be worth taking a look at the following thread: http://us.lexusownersclub.com/forums/topic/52682-blower-speed-mystery-solved/
Jarebear Posted February 19, 2016 Author Posted February 19, 2016 Thanks. I think on the 98-00 models, all of the relays controlling the fan speed were integrated into one (expensive) component (the resister), so I think the linked thread you suggested MAY be addressing an older model.
Jarebear Posted February 19, 2016 Author Posted February 19, 2016 Nevermind, there was a relay for the blower motor under the hood. I replaced it and that solved the problem :)
