Hi All,

My blower only works in the highest position. I have read about it and also read Bentley's. If I understand it correctly, I have the IHKR system. If that is so, then I have neither the small blue "box" nor the knife. I have a black box that has the part number 64118390122 on it. IT has 3 female plugs Blue, Black and White.

REALOEM shows a different part number.

Am I looking at the worong part? OR the probable source of my problem.

Thanks in advance,
Don

Well...it is fixed. I DO HAVE the small blue unit.
I blew it out with my air compressor.

What do you mean you blew it out with your air compressor?

Is it a resistor array?

If you look at the picture you will see that there is a contact in the Blower Motor Relay. In the case of my BMR it had a lot of junk in it. I assume that it is exposed to pre-filtered cabin air. I used the compressed air to clean it out. (The pic is to small to see the contact.)

I have the same blue unit. Unfotunately, replacing it didn't fix my problem. I need to replace the entire blower. I got a used one from Mr. Project a while back but haven't put it in yet.

Symptom of needing a resistor is the fan operates only in #4.
