That's definitely the problem.
Get the new resistor at the dealership. It's located on the passenger side on the firewall behind the glove compartment. I removed the glove compartment for easier access. This is a pretty simple fix.
Unplug the old one.
Remove the old one (a couple screws, I think).
Install the new one.
Plug it in.
I don't think it's necessary to remove the glove compartment, but you don't have to be a contortionist to get to the part if you do.
