Could it be my AC/heater blower motor?

Numbers 1, 2 and 5 on my temperature controller do not work on my 2003 TB. I replaced the controller thinking that may be the problem but still those three levels do not work. Could it be my blower motor? Thanks

Welcome to AF, common problem on these trucks, the blower relay/resistor attached to the blower case up to the left of the back of the glove box, remove r/s lower dash close out to access. Watch for a burnt connector on the relay, also.

That was the problem. Thank you so much!
