The fuse you have seen is for the fans, common problem and the circuit needs rewiring, as does the fuel pump!
As with anything the fuse most likely is not the problem (or if it is there is a reason for it blowing) in any case fuse 24 is for the windows (30 A)
You probably have just disturbed an adjacent fuse, therefore look toward fuse 20 (Has the indicator symbol respectively)
