I keep blowing fuses, I replaced the aux fan because the original one was pretty noisy, the new one is much quieter, however as I suspected it still blows the fuse. It even melted the fuse box a little behind the contact. It will work fine for a day or two then blow, which leads me to believe it's not a short somewhere, could a bad relay cause this?

I'm kind of leaning towards rewiring everything, new relay, new fuse and just bypass the fusebox, however after browsing the forum I am a little confused, some people say the w123 fan has a cooling sensor and a freon sensor, looking at the wire diagrams I only see the freon sensor, so I'm pretty sure that the aux fan is only a/c based, but want to verify.

Like I say I'm really leaning towards replacing the relay and all the wiring and putting in an inline fuse. Unless someone thinks a bad relay could cause fuses to blow?

Thanks again guys!
