Past winter i did a s13sr red top into a s14 with A/C. The harness was from wiring specialist. So i tried to turn the A/C on and i heard the fuse blow in the bay.so I checked the compressor for seized clutch but nothing, looked at the harness for shorts but nothing came up. So i put in a another fused and tried again. But this time i notice when i clicked the A/C button the defrost also turned on for a sec. So i pressed the Defrost button and somehow my A/C is blowing cold air and it still had a blown fuse in the holder. ![http://forums.nicoclub.com/images/smilies/wtf.gif](http://forums.nicoclub.com/images/smilies/wtf.gif)

Any idea why my a/c system is acting like that.

LMFAO. u should be a comedian bro. somehow ur wiring is messed up.

case a; ac turn on. = ur switch wiring to fuse/pre-relay messed up.  
case b; ur defor turn on then ur wiring harness after relay/fuse box messed up. i dont have a diagram. upload so explain better(no access to any right now)
