AC/heat on 2003 Chevrolet Monte Carlo

My ac/heater will not blow out any air, but I can still feel warm or cold air coming from the vent. I recently had a tire blowout on the driver side, which dented the fender and knocked my signal light out could this have broken the ac/heater fan.

Not likely - It is not uncommon for the blower motor resistor block to fail on 2003 Chevrolet Monte Carlos like yours. The blower motor and resistor block are located under the passenger side of the dash. Proper diagnoses is recommended before replacing any parts!
