More than likely, your blower motor has failed. It's also possible that you control unit has failed or you've simply blown a fuse.
Is the control digital? If so, do you get any readings on the display? If so, then that's probably good as well as the fuse for that circuit. If yours isn't digital, then it won't be the control. Your blower motor operates off of its own fuse. So check that next.
As a certified tech, we have a diagnostic procedure that we perform step-by-step before replacing a suspected part.
This would include probing the control unit, the wiring leading to the unit from the fuse box, the wiring leading to the blower motor, and all the connectors in between.
If you're handy with a multi-meter, I suggest doing this before replacing the blower motor. The last thing you want to do is replace the motor just to find out it was only a loose/broken wire.
If you aren't, and don't have the money to take it to a mechanic, then you should purchase a repair manual for you vehicle. It'll give you step-by-step replacement procedures for your blower motor. And it'll come in handy the next time you have a problem, which all vehicles will sooner or later.
Finally, we are a company that depends on donations to keep us up and running. If you're able, something as small as a dollar could help. Thanx!
