Default A/C intermittent

I replaced my battery the other day and driving home noticed my blower wasn’t working. I’m not sure if replacing the batter had anything to do with this. Then I started it up and the ac was blowing. I’ve gone a week now and it’s 50/50 sometimes it blows when I start sometimes it doesn’t. This doesn’t matter whether I have it set hot or cold. Where should I start?

sorry i thought you had said that at some point the A/C was blowing... so is it the blower itself that's intermittent or the switching from hot to cold?

getting to the top of the motor is quick and easy, but I just don't remember any wiring or connections to be honest.

I do know that the bottom of the motor is really easy to see/check when you take the glovebox out - I took mine out in around 20 minutes last week its just a case of removing 8 or 9 bolts. Once out you can see all the servo motors and see any sticking, I think the blower has a servo motor as well - that could be sticking which is why I originally mentioned it.

here's a link with some good photos for you:-

and this is the servo motor i mentioned on the blower:
