My radiator fan doesn't work unless I hard wire it to the battery. I've been having a/c issues at idle lately and I think this is part of it. I figured since the fan wasn't coming on at all it was probably one of the relays under the airbox, but I can't find them at any parts stores! I've been to 4 different places and found 1 of them, but it was $40 and they had to order it so I want to make sure there's nothing else I can check before ordering it. Is there anything else I could check that might be causing the problem? The fuse for the fan looks good. Also, do these relays have anything to do with the a/c, because since I've taken them out the compressor isn't running anymore. Thanks!
