2004 Trail blazer windshield wiper fuse location number

SOURCE: where are the sparkplugs located on a 4.2 inline 6

Under the top of the engine there is a cover. Remove this plastic cover and under you will find an individual coil on each cylinder held in place by a bolt. Unplug the coil, remove the bolt that holds the coil in place and twist apull up gently to remove the coil boot. Under the coil is the plug. Use platinum plugs that are rated for about 80k miles so you don't have to do this procedure but once every few years. Hope this helps, good luck

SOURCE: rear windshield wiper stopped working, its not the fuse

Their on the frame rail, passenger side, midways. I just changed one on an envoy two weeks ago, which is basically the same type of vehicle.

Fixed the wiper problem which was identical to Brad's by changing out the wiper module which is also called a pulse module or something of that nature. Pretty easy fix. You have to remove the grill that the wiper blades protrudes from in order to get to the motor (4 clips in front which can be removed by hand, remove radio antenna, a center push down retainer, two plastic end caps which pop off and then 1 star type screw on each end under the end caps). Getting the blades off seemed difficult. I used a small puller to pop them off after removing the nuts.

You can't buy this module at a regular parts store. I had to get it from the dealer so be prepared to spend $130 to $140 for the part or go to the salvage yard. Works great now.

SOURCE: M y radio stopped working on my 2004 trail blazer

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.
