1995 LS 400
On Tuesday I fixed my car. I found an old post on this site and they said if you had a Lexus dealer installed phone that might be your radio volume problem because of a feature for the phone mutes the radio when a call comes in. The post said to disconnect all the connectors to the phone ECU located in the trunk on the far right side and to take the 2 connectors that come from the front of the car to plug those 2 together and viola I got my radio volume back! So then I did a lot of searches for the blower motor problem and finally found something on the lexus owners site that said if you had a Lexus dealer installed phone that might be the problem because the phone system also mutes your blower fan to its lowest setting. But the instructions to fix it were the same as the radio fix to disconnect the phone ECU since I already did this fix to fix my radio problem I was stumped because the fan was still stuck on low. So I was sitting in my car with it running at my house thinking I will disconnect the battery for a while and that would clear things up and the fan would work....no it still did not work. I was convinced it had to be still related to the phone so with the car running I opened up my trunk and disconnected the 2 connectors that I had connected when I was trying to fix the radio and Bingo my fan was working again! So my advice is if you have one these phones in your car make sure it is disconnected!
Thanks everyone for the help and for the previous posts for me to find.!

Glad you found the problem and that it was so simple. And thanks for the summary (solved) info above. Might make it easier to find in the future...

I never had you problems but I disconnected the phone and plugged those connectors in the trunk a long time ago. I just recently pulled the whole system out and put an ipod in the space the phone used to occupy.
