well today i was driving and i got hit by this one lady that ran into.It was the whole drive side fender and broke my corner light.Anyways after i got bak into my car and started it up i noticed that my heater was blowing as it should.It was set on 4 but it feels like its blowing like its at a level 1.Do you guys know what the problem could be?

 

hmmm, maybe the impact jarred a wire loose?
