The fan only runs on hi speed. I have a new modulator and I want to replace the old one.
How do I get to the old one to replace?

Welcome to the forum, is it the resistor block you want to replace?

I have removed the glove box.
I can see the blower housing.
The top of the blower housing tilts back and the blower wheel spins free.
I cannot find where to put the rplacment part.
It has a 6 prong female fitting, and a 2 by 4 "card" attached that has printed circuits and 4 nodules.
Is that part on the back side of the blower housing?

Thanks,
Craig

I tried to find an exploded view of the system, haven't found it yet. Look at the color of the wiring to the resistor connector. Are we talking about the same part? As far as location, my info just says attached to blower housing.

Yes, we are talking about the same part.
I still can't figure how to get at it. It must be directly behnd the blower housing.

Thanks,

Craig
