Been having some problems with the AC blower in my wife's 1999 LX. The fan just makes a clicking sound when you try to turn it on. It used to be that you could bang on the dash and that would get it to turn on, but that's not working anymore. Is there some sort of relay or resistor that needs to be replaced? If so, where are they located?

Also, the car is regularly parked under an oak tree. I'm afraid that the AC intake ducts are clogged with leaves. What's the best way to clean them out?

 

my guess would be that the fan switch is bad - based upon that you could bang on the dash.

i would think that the best would be to remove the cowl under the hood to see if there is any debris in there.
