Ram 1500 heater fan quit

I started backing out of drive with a/c on and blower running fine. All of a sudden the blower just stopped. Checked fuse and it is good. What do I look at next?.

What year is your Dodge?

2003 Ram 1500. I've read some post that say maybe ign switch?

There are a few things that can cause your problem.
See if you can download this 2003 service manual then look at page 2801,

I read on a post that tilting the wheel may help. I started truck, turned on fan, no fan, tilted wheel and fan came on. Not sure what that means, but kinda scary. Bad/loose wiring?

I looked at the YouTube video. Looks pretty simple to replace. I would never have suspected the ign switch, Thanks for all the help
