I tried to turn on my air this past weekend and noticed that my air compressor won't come on. And, I got up one morning and noticed my rear defrost doesn't work! Does anyone knows what could be going wrong? I did blow a fuse when I was doing my signal light mod by mistakenly taping a hot and ground together. I replaced that fuse. So I am wondering could it have blown a fuse for my compressor and rear defrost, even though I checked all the fuses and they were fine.
