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.
I recently replaced the blower motor in my 1992 LS400 with a after market part, the install was clean with all connectors and fuses reattached. When I went to start the car the blower began to work however, the car would not turn over as if the fuel pump was turned off. I did not disconnect the battery before doing the install. After several attempts of starting the car I disconnected the battery cables for approximately 1hour hoping that it would reset the computer, well that didn't work either. I checked all the fuses and there were none blown. Prior to fixing the blower there were no problems with the car starting at all. There is fuel in the car, and when I turn the ignition I can hear the clicks from the FP relay, but cant get no action........Need Help....Any suggestions?
