My heat will not blow very much but if i set the temp to 60 degrees cool air blows great

What is your question?

I just put in a new blower motor and on heat I only get very little from defrost blowing but when I turn it down to 60 degrees it blows cool air good from the dash. On 90 degrees I get nothing from the dash and very little from defrost.

What makes this problem better or worse?

Bad all the time

How long has your 1994 Cadillac DeVille had this problem?

Since I've had the car
