Cabin fan, not much air blows in

Hey guys, I'm new here cause I just got my truck. I have a 1998 tacoma Sr5 , 4cyl automatic.
My problem is I'm getting very little air into the cabin. The ac is cold, heater is hot. You can feel it in the dash. Just the air is not pushing it out. I can hear the fan blowing. Need help
Thanks in advance.

 

your cowl/venting might be getting clogged up or the blower motor may be failing. there is no cabin air filter on that year model

 

The fan works. Its the air coming in. Its not enough. I think coming is blocking the fan from outside in, if that makes sense

 

If something was blocking it from the outside, your truck would essentially just be running as if you had the recirculation button activated. Is the fan working at all speeds?

 

If it has a Cabin air filter, change it. It will make a difference, because it's clogged with debris and dirt. Worked for me.

 

the blower fan is under the passenger side dash. I bet the plastic tubbing just fell off. take an hour or so and pull the dash and make sure all the tubes are connected.
