most likely the resistor module for the fan (if you have the manual blower and not the Digital one).
Usually 1 or 2 speeds go out. but not unheard of all the speeds to go out.

Its about $25 part. can be changed easily-
its behind the glove box.


It could be another problem--- but the resistor module is fairly common

The rear seat A/C has its own blower, mounted under the dash, on top of the transmission hump and behind the floor console.
