About a week ago my fan stopped blowing completly. I have no idea what to do. It blows cold or hot air whichever is turned on but its the same air flow whether it is one low or high. i just had to change the water pump yesterday (not sure if the problems are related) and nothing changed. I also checked the fuse box and everything is in order. Not sure where to look next or if this is a common problem. Again the heating and cooling works just not blowing it in the cabin. thanks in advance for your imput.

 

Does the sound change when you pick a different speed? If so, then you might just have trash in the blower box. If it stays the same, maybe you've got a bad resistor Resistor - Climate Control Blower Motor (Genuine Part # JGN100011) or Resistor - Climate Control Blower Motor (Genuine Part # JGN100010) depeding on VIN.

 

has no sound what so ever. like i have no blower at all

 

Look under the glove box. You should see a hole in the cardboard trim. The blower motor sticks through the hole. Give it a good firm tap and see if it kicks on.
