I have the base base model. The blower motor will not run properly unless I am pressing it in and holding it there. I thought it might have been the plug itself so I bought a new one, connected it, and got same result. I do not know what to do next. Would it possibly be the resistor? Also, what is the easiest way of getting to its location?

Hello, I am Danny.

It is usually a little bit easier to replace the blower motor resistor by removing the actual glove box to gain easier access. I have attached a picture of its location. Be sure to look and see if any wires on the harness look burnt/melted that is usually what happens. Hope this helps and feel free to ask any questions if needed. Thanks for using 2CarPros.
