Blower or gnition problem?

My right hand blower fuse pops when I start the car, I can remove the fuse and start the car then put the fuse in and all is good? With the car off overnight the battery dies, the fuse doesn’t pop when I turn the car off? Thoughts?

Sounds like you need to do a draw down test to see what circuit is drawing current while the car is asleep.

Does the fuse pop with the blower switch in the off position when starting the car ?
Was / is the blower making any more noise than usual ?
With the car turned off have you listened to see if the right hand blower is still running ?

yes,no, and no.
