94 Cavalier AC/Heat problem....

[jpohlhaus]

Help- I've search the threads and posts and can't find my exact problem!
When the ac is turned on you can hear the fan running- it changes from low to high and you can hear the different speeds- but the air flow coming out of the vents is almost nothing- it does feel cool- but you can hardly feel it. When you switch to defrost it does come out the top and it gets alittle stronger- the heat seems to be the same way. We checked the hoses and they seem fine, and the fan is working.... Any suggestions greatly appreciated....

I would check the ac condencer behind the glove box near the blower motor they get clouged and will restrict the air flow

defenitely sounds like a clogg or duct work has come off/loose
i think main/1st duct closest to blower from your discription

maybe mechanism for switching the vents is not opening/closing right. I haven't checked this car, but I assume this model is mechanical only. Others higher end cars have vacuum operated vents. Loose or leaking lines caused the air to not be directed where you think.

good point the door could be stuck or in default mode

Well the "door" was open- we closed that and it didn't make a difference for the vents in front or the defrost, but I do feel a small amount on the floor now....ran out of day light- will check duct work tomorrow. The air is going somewhere- just can't figure out where-
Thanks for the suggestions!

Let us know what you find.

Well we are at a loss....no clogs we could find- or lose or off hoses! Vacumm lines seem to be all connected and working. Put a new blower motor on just to rule that out... that was advice from a friend- it was only $20 so what the he$$- didn't make a difference. Condensor looked ok.. Got another friend that is gonna look at it this week- if no luck I guess it's pay someone to find the problem- can't have my kid driving it with no heat or defroster this winter! Can't think of anything else to check

if you have good connections on air ducts you changed blower
did it come with new squirrel cage/blower wheel??
the only other poss. is air intake
check fresh air intakes???leaves nest ect

I think my husband took the air compressor and blew them out...I'll check! He did get some leaves and debris, but didn't seem to make a difference. The blower motor did come with a new wheel, seems like the defroster is a bit stronger, and I had the heat on this morning I think that is stronger now, but when it's on the a/c there is hardly any air. This was the first morning it was cool enough to actual feel the heat coming out....most of the time it's been 90+ degrees when we are working on it! Got a mechanic friend looking at it tomorrow- will post an update!
