How To Replace A Blower Motor In A 2005 Chevy Trailblazer

I assume the fuse box locations for a 1997 Olds 88 would be the same as for a 1999 - which are: (1) In the lower cover panel below the instrument cluster just left of the steering column - with a snap-off cover. (2) Passenger side 'kick panel' - side panel under the dashboard just forward of the door - lower cover panel underneath the dashboard and next to the firewall must first be removed. (3) Under the hood on passenger side on the firewall - need to remove black plastic outer cover (1/4 turn finger latches) then two black plastic inner covers (side spring latches).

Remove lower kick panel passenger side, blower motor in inside heater case, very close to the passenger door, behind glove box. From under the glove box look up to find a circular bulge with 5 (7mm) bolts around it, remove the 2 wire connector (black and purple). Remove the five bolts, drop down the blower motor, transfe over cage if new one doesn't come with one, reverse to reassemble.

NO NEED TO REMOVE WHOLE DASHBOARD!!! REMOVE TWO7MM SCREWS FROM THE BOTTOM OF STEERING PANEL & PRY AND REMOVE PANEL.
NEXT REMOVE TWO 7MM SCREWS ON BLACK PLASTIC STRIP THAT YOU SEE AFTER REMOVING STEERING PANEL....PRY THIS STRIP OF PLASTIC OUT JUST A LITTLE AND CUT IN THE MIDDLE .
NEXT REMOVE TWO 7MM SCREWS FROM AROUND TOP OF INSTRUMENT PANEL (BY GAUGES ) PRY PANEL STARTING FROM AROUND VENT ON LEFT BY DRIVERS DOOR ""THIS PANEL WILL STAY IN PLACE LOOSE... NO NEED TO REMOVE!""
NEXT YOU WILL SEE 0NE 7MM SCREW BY GEAR SELECTOR AREA.. BEHIND THE LOOSE PANEL REMOVE THIS SCREW.. ALSO IN SAME AREA BUT LOWER THERE IS ONE 7MM SCREW THAT NEEDS TO BE REMOVED THAT HOLDS LOWER DASH PAD ITS FOUND BEHIND LOWER CORNER OF DASH PAD.( LOWER DASH PAD GAS PEDAL AREA )
"DON'T"!!! REMOVE THE FOUR 10MM BOLTS!!!! IN SAME AREA
NEXT REMOVE RADIO /AC CONTROL TRIM WITH THIN SCREW DRIVER OR PANEL TOOL IT HELD IN BY SIX CLIPS...NO NEED TO DISCONNET ANYTHING IT WILL STAY THERE HANGING!!
NEXT REMOVE TWO CENTER CONSOLE LOWER LARGE PLASTIC CLIPS BY FLOOR MATS. NEXT UNDER SQUARE BLACK RUBBER AT CENTER CONSOLE REMOVE ONE SILVER SCREW. MOVE SEATS FOWARD AND REMOVE TWO 8MM SCREWS FROM SIDES OF CENTER CONSOLE FROM BACK SEAT.
PRY CUP PANEL SECTION THAT WAS HELD DOWN BY SILVER SCREW ...PRY UP TOP HALF OF CONSOLE STARTING FROM SECTION WHERE ARMREST DOOR IS.. DISCONNECT LIGHTER PLUG AND REMOVE PANEL .
NOW YOU WILL SEE SIX SCREWS STARTING FROM BELOW RADIO TRIM WORKING BACK TO ARMREST DOOR

Yes. It's under the glove box, behind the plastic cover. On the very bottom ther will be three screw (7mm) take those out next there will be a thin plastic cover that has another 7mm screw in the back towards the firewall. The filter will slide staight down, and there are two. Slide the first one out then slide the second one out.

Remove air intake hoses to throttle body, remove battery tray, remove washer bottle attached to battery tray, remove clutch slave cylinder and compensator from the top of the tranny. Remove tranny gearchange control cables and hang up to one side.
Jack car up as high as you can and remove the wheels. DRAIN the gearbox (24mm not on bottom side).
Now go under the car and remove the starter motor, remove the exhaust front pipe (can unbolt from front CATs and let hang down), remove frame member and remove the plastic covers from the passenger side wheel well to get to the frame member. Remove the lower control arm bolts on both sides and let the control arms hang down. Disconnects both sway bars at the wheel hubs to allow the drive shafts to be pulled outwards. ease the drive shaft on passenger side out with pry bar and have someone pull on the hub to pop the drive shaft out. On the drivers side, you have to first remove the intermediate bracket on the block and then do the same thing with the drive shaft to pull it out.
Support the tranny with a jack.Remove the four bolts holding the tranny support bracket (covered with four grommets in passenger wheel well). Remove the three bolts from the top of the tranny and remove the bracket.

Now work your way around the tranny and remove the bolts holding it to the engine (there is a 10mm phillips screw/bolt holding a dirt sheild in place under the rear of the tranny, the other bolts are more obvious).

Tranny is now ready to be lowered to the floor using the floor jack.

Installation is the reverse of the above. Good Luck.
