The fuse you are blowing is the 15 amp fuse for the VCC, a/c compressor and for the power steering switch. The VCC is for the trans, when this fuse blows you only have 2nd and 3rd gear. you have to find the short in the caddy that causes it to blow. I have to find mine as well. if I turn on my defrost it blows, if use the A/c it blows but sometimes not for a day or 2. but with the defroster its immediate. I think my problem lies in the climate control. you will have to find your shorted wire.
