06.5 A/C keeps blowing fuse

[Foots]

I have an 06.5 that keeps blowing the under hood A/C fuse. A while back, I hit my knee on the climate control knob and broke the trace in the motherboard behind it, making it where I couldn't change the temperature. A mechanic I worked with soldered the connection back together, and everything worked fine all summer. Last week, though, the fuse blew. So I pulled apart the climate control unit again to find that the soldered wire had come loose. I went ahead and bought a new climate control unit and replaced it, but the fuse keeps blowing. I have also noticed that my temperature adjustments skips 61 and 62 degrees and goes straight from Lo to 63 degrees and vice versa. It did this right before replacing the unit and also is doing it after. Does anyone know where the fuse under the hood leads or where I can find a wiring diagram?
