Heater fuse.

[WotDa]

So, last night my sister wanted me to take her out, the car was a bit frosty, so I whipped the di-icer out, then turned the heater/fan on to get rid of the mist on the inside.

This is when the fuse went, for the second time. So, is it something I should get checked out, or can I just whack a 30amp fuse in instead of a 25?

Thanks in advance.

Never put a higher rated fuse in, all that will do is cause the wiring to burn instead of the fuse to blow, oh and if discovered your insurance will be invalid(if the car combusts and you have to claim)
