I have a 1995 LS400 the blower only works on low speed everything else appears to work fine has no codes.

 

try 2 clean TB.

 

Please explain

 

Did this problem just start ... i.e. was the blower working properly until recently?

My first question when I hear about this problem is ... has this car ever had a dealer installed Lexus phone system? The Lexus phone system automatically turned the blower speed to low during a phone call. Sometimes the old phone systems go a little crazy -- even when no longer used -- and set the blower speed to low. Also, improperly uninstalling a Lexus phone system can make the blower operate only at low speed. If your car never had a Lexus phone system, then disregard everything I just said.
