I had mine replaced last year, but quite frankly it SUCKS. The heat gets really hot nice and quick, but it BARELY moves any air on high. Like I can barely feel it coming out of the defroster vent. It sounds like it'* going full swing, but sure doesn't feel like it. Is it possible that there is some sort of obstruction or does the blower just suck?

There could be an obstruction

This is from a 97 SSEi. The pine needles you see accumulating are the beginings of a blocked evap core. This amount however wouldn't cause any problem:


This is the blower housing from my 90. Here you can see a rodent nest. This would cause some air blockage:


This is the evap core. This is mostly clogged with general funk, some of the rodent nest and maybe mildew. This amount of crud can definately block a good amount of air:


You can remove the Blower Control Module and inspect the blower housing for contaminants. You could also use a shop vac and slender tube to remove most of it. As far as the evap core fins go, I've heard of a foaming cleaner that can be sprayed on the core to clean and disenfect. The idea is to spray it in, let it foam up and do it'* thing and then rinse it off. Obviously, you would want to do this in a garage so you don't have an ice build up this time of year. Also, you want to make sure that the evap drain is clear before applying.

The other problem might be that although the ECC display indicates that the air should be coming out a certain vent, it might actually be coming out the defrost vents. This can happen with a loss of vacuum to the programmer. Just give that a quick check before digging into the blower housing.

I cleaned mine on the SSEi and on Jseabert'* SSE without removing the cover. Only the inspection cover on top. Procedure is in Techinfo.

Agree with WW.. head for cleaning first.

FYI: Randman illustrated because he had to pull the evap cores on both cars.

Had issues like that with mine. Went and did proceduere to clean and there was no dirt. You could have a problem with air flow. What vents or doors open. Mine sounded the same way. Blows like mad but no air. Sucked.. I fixed the airflow problem but now my motor ( blower ) went out.

Check to see if when you change from top to bottom to middle etc. That you feel air coming out those places when you make the change... If not your air flow doors arent working properly...
Let me know

The airflow does get redirected when the direction changes. I don't know where I'm going to try to do the cleaning if I need to use water, since my garage isn't heated. Maybe I'll have to go find an underground parkade or something.

Good luck sounds like that is a good path to go...
