I have an a/c but its been below 70degrees here for the last few months and haven't had the chance to use it. I got in wreck while back and it bent radiator support a lil bit. the radiator and condenser are fine but the condesner clips on top came off. I checked all of it and nothing there was loose or broken. Its too dam hard to tell what it is. I have had it looked at and everything. i drove it around with mechanic in it and heard nothing. after i left it started. I am about to just fix the front and sell it and get a new Si.
