This 2004 Pontiac Grand Prix came in with a complaint that the blower had stopped working and the customer saw smoke from under the passenger side of the dash. Inspection at the under hood fuse box found a blown 30 amp fuse.
I replaced the fuse.
The new fuse is the square pink fuse second from the left.
I checked and found the blower would work but made a terrible noise and would not turn off.
Time to change the blower motor and blower motor speed controller. I started by removing the passenger side lower hush panel by removing several push pin retainers.
I removed the courtesy light from the panel.

Then I could access the motor assembly for removal. Three screws and a harness connector and it was out of there. The blower motor speed controller was put on at the factory by melting retaining bosses to hold the assembly together.
I had to use a screwdriver and pry the unit from the housing and installed the new one with screws to hold it in place.
I also checked and replaced the dirty cabin air filter which is probably what helped cause this problem. Click here to see that post.
I have something like this going on. My 04 Grand Prix about a month ago started intermittently cutting off (air). Most of the time it would cut on after a couple minutes. Sometimes as I was driving it would cut in and out. Now it’s not blowing at all. It never smoked though. What should I check first?
I am afraid it was just a coincidence or there is a poor connection in the fuse/fuse box. Fuses are not directional. Well only if you tend to be a little OCD like myself.
That fused you switched, I simply turned it around and put it back in and my blower started working.. Totally weird.
reason why I did that was because the number on that fuse was opposite way of the others..
Still mean the fuse is bad?
Great information,best I could find on the net.
