The Service Manual provides the part numbers for most of the connector terminals, but nothing in regards to the fuse block. The cost of a new fuse block, at $312.91, US DEaler price, would be nearly prohibitive in Canada. BLOCK-UNDERHOOD BEC. Fits: CANYON, CANYON Crew Cab, CANYON EXT CAB, CANYON EXT LENGTH, COLORADO, COLORADO Base, COLORADO Crew Cab, COLORADO EXT CAB... | Nalley Buick GMC Brunswick
Maybe you could find one in a junk yard. I don't know what differentiates the fuse blocks from one year to the other, except the size changes of the relays from "Mini" to "Micro". It appears that the part number of the block (25933296) was only applicable to the year 2008.
