Answer
Hi Orville -

There are 2 things you can check.

1. Check your cabin filter (have to remove the glove compartment to get to it). If it is clogged, you have restriction.

2. Check the A/C door. This is within the duct center under dash. This door directs air either to the defrost vents, floor, or center vents. Could be stuck in a prtial position.

Hope this hyelps -
