Last weekend I installed factory cruise control, which I picked up on eBay, on my '91 245. The process went well and works perfectly thanks to the info I found on this board. Following the installation of the cruise, the blower motor ceased to work. I didn't have much time to dig around and try and find the problem. I plan to dig deeper this weekend but, before I do so, I am hoping that someone my have an idea of where I should begin.

Here is what I verified last weekend:
• I checked the fuse, cleaned the contacts, and verified the voltage on both sides of the fuse.
• Looked through the mess of wires under the knee panel, where I did the cruise work, to try and find a disconnected or broken wire. When I found nothing here, I took the center dash trim off.
• Verified that I have power in and out of the rotary fan switch, which confused me, as I assumed I had interrupted power between the fuse block and the fan switch, where I had done the cruise work. I didn't mess with anything during the installation between the switch and the blower motor.
• Verified the grounding point of the blower motor.

Based on that, can anyone suggest places to look that I may have damaged while installing the cruise? I did all of the work on the cruise with the battery disconnected, as well.

Thanks on advance for you help.
