Yes, as long as you're using the same short wheel base OR extended wheel base.

that is strange. for the ABS has its own relay and so does the heater blower motor. they do not share the same outlet , I would check the wire at the bottom of the fuse box

if the light doesnt come on the compressor is not engaging the clutch. possible wiring problem. check a/c clutch relay. may be faulty compressor or the system may be completely empty of refrigerant

This vehicle is a chevy trail blazer , doesn't matter yours is in the same place an the samething .

Typically it is a 255/65R/17 or 255/70R/17

maybe a fuse the fuse box is under the drivers side passenger seat . sometimes ive seem them get something spilled on them and i had to wiggle the fuses to clear the corrosion

On 05+ Trail Blazer, the fuel filter is integral with the fuel pump inside of the fuel tank. It is a non-serviceable part. On 02-04s, the filter is on the drivers side frame rail at about the B-pillar. If your trail Blazer is a late 04 which means that it was build close to the 05 Trail Blazer, you may have a non serviceable fuel filter. Good luck and check under your Trail Blazer or look at your manufactured date sticker on the door which would help you indicate if your 04 is a early Trail Blazer and you'll have the fuel filter on the inside frame rail under the driver's door.

The 2004 Trailblazer has two fuse panels, one in the under hood and one under the middle row seats. The radio fuse is marked RADIO fuse # 41 and is a 15 amp fuse located in the rear fuse panel. To access the rear fuse panel flip the seat behind the driver to the upright position, under it you can see the fuse panel and a diagram should be on the under side of the cover. 

Good luck and hope this helps.
