defrost blower '93 Pathfinder

Humboldt · Post by **Humboldt** » Thu Dec 16, 2010 3:58 pm

I've got something caught in the defrost blower for my Pathfinder. It sounds like it's straining, I can hear something caught in it, and want to fix it before it overheats the fan and burns it out.

Any ideas how to go about this? Not sure if I need to remove the console or not.

Any advice appreciated, I haven't found anything online yet.

Thanks

Good suggestion, have been meaning to pick one of those up for years.

If I remember correctly just take out the glove box and that will give you access to get to the blower motor. Remove the 4 screws and see what you get on the other side.

Thanks for the advice, Rainbow.

Would that be just the glove box itself (everything that swings down including the door) or the portion of the console that surrounds the glove box door as well?

There are no directions in alldata just a picture. It is a .9 hour job for a skill level B tech, so it is fairly easy. Looks like through glove box opening. Also there is a TSB.

Thanks for the help, I appreciate it.

If it stops raining I'll be out there today.

2 questions...when you say through the glove box opening, do I open the glove box and that gives me access to the screws I need to take out, or do I take the glove box out completely. I'm guessing neither method involves removing any of the console.

Second, what's a TSB?

thanks again.

Technical Service Bulletin. Open the glove box, it should be clear, I would think. Have not done one of these recently.

Well that was fun...took 2 hours and 3 beers.

Taking the glove box out, seems straight forward unless you avoid breaking those damn pins that hold the corners in. Are they supposed to be one use?
Beer

Took the blower out and, what a surprise, it's jam packed with dog food

Could've used a little Asian hand to get that 3rd screw, damn

Before I put it back in I felt what it drew from to make sure there's no food that could fall in to clog it again.
Beer

Story 2: big ass black box with an opening leading into the blower motor. Sat just to the left of it. Had some filters in there that I guess filter the air it draws in before putting it through the blower. Filters to the left, huge open space full of dog food to the right.

No clear way to remove the damn thing. All bolts off and it wiggled a bit but wouldn't come off. Ended up pulling an access port off the front (electrical plug of sorts).

Cut a short section of small diameter PVC and duct taped it to a shop vac. Vacuumed out the space and cleaned the filter best I could.
Beer

Put it all back together.
