2003 H6 Outback (Auto Climate Control)

 

Was driving on the highway yesterday (Car was well warmed up)

 

Heat had been working fine, then all of a sudden no air at all was coming out of the vents. Blower motor was on high and it still sounded like it was working properly, just no air at all (not even cold air) was blowing out of the vents. I kept switching between floor vents and front vents and window vents. Turning the fan on and off. Eventually after 20 minutes it started working again.

 

I had a similar thing happen about 1 year ago and some grey foam shot out of the vent after and it started working again.

 

This time nothing came out of the vents, but I'm wondering if it's somehow possible I have an obstruction in the vents somewhere ?

I bet you have a whole family of critters somewhere in there.

Grey foam? dry? Liquid?

Since you get no air at all, i presume the blockage is in the air inlet to the blower motor. You could have a look there. The motor is behind the glove box and accessible without removing the box in my car. In yours?

Good luck!

No liquid, dry grey foam pieces (the kind you see that seal around the vents)

 

How hard is this to get at? I'm not great at removing panels/dash stuff, I usually end up busting plastic pieces, clips etc.

On my 96 Leg, you can access the blower motor with some contorsions. Have a look just under and behind the glove box and you'll see if the motor is accessible without removing the globe box. If you have to remove it, get a Haynes manual or wait till someone tells you exactly how to proceed.

 

Edit: have a look at another post on this page or on the preceding one: «blower motor makes whirring noises».

Perfect thanks, I will see if I can locate it tonight.

Had a chat with my subaru guy he thinks it maybe the air divertor was closed(vacuum powered on top of heater box)or blower motor fan cage had let go and was slipping for a few minutes.

 

When it wasn't working I couldn't even feel the slightest feeling of heat from any of the vents, and then when it started working again it was blowing out really well, almost makes me think maybe it wasn't an obstruction.

If you had it on Recuirculate it has to suck the air from somewhere in the car, typically from behind the glove box. Maybe it sucked something out of your glove box and into/onto the inlet for the blower? This actually happened to my wife in her 2005 Pontiac Vibe. Sucked Napkins out of her glove box.

It wasn't on recirculate, was just on outside air, although I switched it back and forth a few times when the problem was occuring, but it didn't help.
