At first when the A/C was on my passenger side kept leaking into the floorboard for about 2 weeks. Then no water at all for a week. Now no air at all hot or cold comes through the vents. When the heat is on my car still heats up, just doesn't blow.

So if you don't have blower operation, we have a number of things that could cause this. The relay, switch, resistor, or blower motor. I would start with testing for power at the motor. If you don't have power then go backwards in the system until you find where you have power. At that point, you will know where the issue is.

I included the wiring diagrams that will provide the detail you need to do this testing. Let me know what questions you have. Thanks
