I have a 2005 pontiac grand prix. The car has had no mechanical problems except recently when I turn my air conditioning or heat on, you can hear the ac click on, but no air will blow from the vents. Sometimes it will come on, but its inconsistent. I can get very little air blowing through the vent or it comes on full force. I had someone tell me to check the fuses and the relay switch. The other day it wouldn't turn on and I opened the glove box to get something and shut it...the impact caused the air to blow. Any suggestions?
