Hello everyone, i have a 1997 Dodge Ram Station Wagon, and my air vents dont seem to put out much pressure. these hot summer days are getting the best of me. some people i ask, tell me that my cabin air filter is clogged but from my research and personal inspection, i believe i dont have a cabin air filter in this model. What do you think it could be??? bad blower motor? flapper door? or Clogged AC condenser? the air thats blowing out is cold and you can hear the blower running at full speed, but when you put your hand close up to the vents there is barely any air pressure behind the vents, it is just barely seeping out. all fan speeds work with the lever. If anyone could help me out that would be awesome. Im a mechanically inclined being but cant seem to figure this one out.

 

Not sure how hard it is to pull the blower motor on your van, but, an evap core packed full of leaves and other stuff that finds its way in there, wouldn't surprise me.

If you put it on max a/c, does it get any better?

 

So I went through this recently when I replaced my dead blower motor and blower switch. So in my van's case, the vacuum lines are what make the doors inside the ducts move from defrost to dash vents. So if you have a leak in those vacuum lines, or the check valves in those lines no longer work, that compromises the vacuum and the doors won't open. Usually that means great air flow in defrost but not dash vents. I patched my line and replaced both check valves, but what really happened was I knocked a line loose under the dash to the actual control switch in the dash. Once that was reconnected it blew correctly in dash, feet, and defrost.

Removing/replacing the blower motor is pretty straightforward if you know where it is. In mine it was three screws and one plug in electrical connection. The difficulty lies in how easy is it to access.

I tried to look it up but I don't see a 97 station wagon, only the 97 Wagon which is effectively a van. If you have that, our models are probably close enough I could refer you to the thread where everyone helped me fix my issue or show pictures/diagrams where thing probably are.
