How do you replace the front blower motor on 2007 Nissan Quest?

Answer 1

These instructions are for a 2007 Quest with Nav and Dual Climate Control. It appears from the parts book that this is applicable to all models, but I can't guarantee that. I have pictures of this process from start to finish if needed. This is a little tricky and took me a few hours to figure out, but can be done in a couple hours easily.

1. Remove cover behind Nav system. This is done by using a plastic or other soft tool to pry at the front, closest to the windshield, and working around. It should pop up easily.

2. Remove the tray that holds the GPS antenna unit and small speakers. 4 phillips head screws. Remove the 2 screws holding the GPS unit.

3. Lift up this tray removing the GPS antenna, and unplug the two speakers.

4. Remove the Nav screen and computer by taking out the 4 phillips head screws on the brackets behind the screen. Then pull up and the unit should pop up. Unplug the computer and the Nav screen from the harness.

5. Remove the two black 8mm hex head screws holding the defrost ductwork. Now here's a tricky part: you have to remove this duct which is a real PAIN. pull up hard on the front, closest to the windshield, until it pops past the connection to the windshield defrost outlet. You have to deflect it a lot, but it will come.

6. Now looking down you will see the top of the blower motor and double squirrel cage fan unit. There is a large two-wire harness that you will unplug.

7. Now remove the four silver 5.5mm hex head screws (or 7/32") that secure the top housing of the blower motor unit. It helps to have a 1/4" drive with a Universal Joint to get to the front two screws.

8. Pull hard upwards on this top housing to break the sticky seal and this unit will come out along with the motor. You may have to work it slightly side-to-side to get it to come out of the ductwork. Also, you have to roll it and force it slightly to come out of the hole in the dash left by the Nav removal. It likes to get hung up on the defrost outlet duct opening, but it will come out.

Now you can test the unit or replace it. Putting the motor assembly back in requires a little forcing to get it past the defrost duct opening.

The real bugger of putting this all back together is getting the defrost duct back in place. There is a wire harness jammed in the same area, and the duct will really want to hang up on the silver 5.5mm screws that hold the motor unit in on the rear, away from the windshield. I found that using a long, plastic pry tool will help pop it over these. Also, the duct wants to tuck slightly to the driver's side, not centered in the hole. You'll just have to work at this to really force it in, but eventually it will pop into place. Then adjust it so it lines up with the front defrost outlet duct and you're in business.

Reinstall the Nav system (don't forget to plug everything in). The screen harness runs up through the mount bracket on the driver's side.

Reinstall the tray and GPS antenna.

Snap the dash cover back into place. Viola.
