Is the engine operating temperature reading normal?
Do you have a volt meter? You can do this check yourself if you do.
Passenger side where the feet would be, right above there, remove the sound insulator panel under the dash. You may need to pull the carpet away a little. You should see the bottom of the fan motor with the fan connector. Remove the plug and turn the fan on and see which wire is the positive. In the wiring diagram I have they both are black. Then you would match that to the motor. Then take 12v positive and a ground and touch both pins on the motor to see if the fan motor spins.
Do you have dual zone climate control?
Does the air come out the same in all the other vents too or is it stronger say in defrost or on the floor but not the same on the dash vents.
You also may have a blower motor control module.
If you can do any other checks on the system that would help. That is in high heat with the selector on defrost, the fan works the same in all speeds or not in some or never goes on high but the other speeds work okay. Then on vent do the same test etc.
