Review on 🔌 ACDelco GM OE 15-81727 HVAC Blower Control Module by Mark Kolipano

I bought this after my fan motor had a bearing problem. This in turn resulted in an excessively high current which disabled the fan motor and control module before the fuse blew. If your fan is always on, this is what you need. I had to save a few self tapping screws to attach the control module. I used two 10" x 3/4" stainless steel screws. The control module has been drilled with both holes required for its proper installation. The location of this unit made installation more difficult than I would have liked. That's a GM issue, not the part itself. I ended up using a flex shaft accessory on my drill to help install the screw. Installation time was about 10 minutes after removing the other control module. It could be less if I started with a flexible shaft for a drill press. ;-) After installation, the device worked perfectly, I can highly recommend this product.
