Hi everybody I'm sort of new to this, I have a 90 Civic Dx Hatchback and I'm having a problem with my Blower or at least i think that's what it is. I recently tried to turn on my air (to get the air within the car to circulate) but it doesnt work at all. I dont know what to do or how to approach the problem, I recently had an security alarm installed in my car, and had a few friends tell me that they might have messed with some wiring but I'm not too sure if this can be true. If anybody out there could help me out or give me some tips on how to approach this problem i would greatly appreciate it.
