Front air vents not blowing

The air vents stopped blowing a few days after a small piece of plastic about the size of a dime in the shape of a triangle fell in it.

Would that cause the vents to stop blowing?

I also spilled coffee on my dash about a year ago. The controls stopped showing on the display but continued to work, I just have no way to tell the temperature because the display went out.
Would that cause the vents to stop blowing?

I checked the fuses, everything is fine there. And I purchased a new blower motor and installed it and it still doesn’t blow.

Does anyone have any suggestions or advice?

I have so many miles on the truck I didn’t care to replace the dash controls unless necessary as I can’t find the part for under $250.00. Right now I just need it to blow. The back works fine. I found out that the piece that fell in most likely did no damage because the doors open and switch directions of the air. The problem I m having is that even with replacing the blower motor and checking fuses the blower motor still isn t blowing.

Any suggestions?

We got the blower to come back on.
First we replaced the blower motor. That wasn’t it.
Then my husband put a new resister in it. Turns out the resister they gave us was the wrong size. When we installed it at first it didn’t work.
Then my husband started tapping on the other parts underneath and all the sudden it kicked on ( I assume the piece that fell into it got dislodged, but I don't know).
The problem was the resister the store gave us was the wrong size and when I shut off the motor and opened the door the vents still continued to blow. We ended up putting all of the original parts back in and they worked.

The problem I have now is the ac compressor is not kicking on.
It worked before when the blower was not working. It literally stopped when the resister was on.

My husband already tried replacing the low pressure switch and it still won’t work. He jumped it and it still didn’t kick on.

Any ideas?
