Ok heres the deal replaced the blower everything worked fine. Then noticed a small leak in the heater core replaced it. Then blower worked a few times and no longer will blow on any speed. I tested the blower with a hot wire and it still works fine. I thought maybe it was the actual switch in the dash so I went to the junk yard found one in perfect condition replaced that still not working. So a local auto parts store said it could be the blower resister. Well I bought it and cant even find it in the vehicle. Does anyone know where this is located or have any other ideas as to what might be wrong.

Big or small Blazer?
If no blower at all check fuse and power to blower switch.

Does the high blower relay have power to it?
