Blower Speed Mystery Solved

[A. Gaessler]

If your AC/Heater Blower speed always runs 1) low or 2) high, see attachment for fix.

The most likely cause is the linear controller module for 1) , and the resister (resistor) for 2).

It is rarely the $850 electronics module in the dashboard.

This is poorly documented in the available publications and even Lexus service was confused and provided incorrect info.

I will be happy to provide info in pdf, but was not able to attach. If you tell me how, I will.

I have this same problem, blower only runs on high. It started after someone stole my stereo and so kindly cut all the wires to the AC control head. So I had to get the plug ends from a salvage yard and re-wire the whole mess, not to mention a new control head. Now the blower only works on high speed. Yes, it is wired correctly. However I did get it wrong the first time because there are several wires that are color coded the same. So I may have caused something to "burn" out. Anyway if you could send the file to me I will greatly appreciate it. marioanest@gmail.com

I too would like to get a copy of the pdf.... I have a vintage 93 ES300, and have no clue what has been repaired in the past except for the obvious evidence of someone being there before me...... stripped and missing hardware...LOL

thanks

Capnfred57@yahoo.com, if anyone has any other advice for a newbie lexus owner I would appreciate it.... if I figure anything out I will post it here. Also if you have not gotten it yet I strongly reccomend that you get the facory service manual... see the very first post on this board.

On my Lex LS400 '99, I recently replaced my Nakamichi head unit in the dash and now my a/c blower only operates on low, regardless of the display incl automatic. Can I get a copy of the PDF file referenced?

I wish I had found this months earlier, I have this same problem.

[BoaR]

instead of posting all your emails,

just upload the PDF to a service like this -> http://www.2shared.com/

then LINK it into the thread.

that way everyone can grab it and it will stay live.

thanks.

[mmart33]

I have the same issue with the "LOW". The blower runs, but the speed doesn't change on AUTO or MANUAL changing of the speed. It is always a low speed. I changed the blower resistor, but it was not the case.

Can I get this PDF also? My email is mmart33@gmail.com.

Or if anyone else knows what to do, please let me know.

Thanks!

Hi,

I just got my son a '98 ES300, and he is having all sorts of cabin heat problems. If anyone has this PDF please send me a copy. I'm sure it will save me a ton of time troubleshooting.

My air is stuck on low (linear module) could you please send me the PDF on that issue. Thank you. Dmalmed@yahoo.com

[jfblex]

I have the same problem: the blower on my ’97 ES 300 blows only on low. My independent mechanic ran a diagnostic, checked the Lexus documentation, and told me that a ~$900.00 control module would need to be replaced. If there is a less-expensive option, I would very much appreciate the documentation. My e-mail address is: jfbcoun@aol.com.

Thanks,

John

[foxt]

I know that this thread started about two years ago, so I am wondering if anyone has been able to fix this issue? I replaced the blower motor resistor, but my blower is still stuck on high.

Tom

[malmed]

i have replaced the resistor, now i am trying to replace the A/C Blower Motor Linear Controller but i cannot find a part number anywhere to order one or a place that sells is online. Please, if anyone knows any helpful information as to where i can get a A/C Blower Motor Linear Controller please e-mail me t david.malmed@gmail.com

Please send PDF file my ES300 blower motor runs on low speed onlysend to A026643@allstate.com

THE BLOWER MOTOR STOPPED WORKING ON MY 97 ES300 ALSO. ANY IDEAS ?
