    Blower motor,relay question

    Hi,

    I have a 93 wagon with no blower operation at any speeds. The AC does come on and trigger the cooling fans when the fan switch is moved. I read the help section but the pictures are down. The 7.5amp and 30 amp fuses are good.

    Im testing the yel/black and have power with the key on but the blu/red apears to be grounded where my book says this is power ?



    I pulled this relay and jumped both post with no blower operation and testing the same. I also replaced it with a similiar relay i found under the dash same results.



    the harness with the multiple blue wires which I assume is the blower resistors its the same the larger blu/red is ground?



    Im just going to assume from the search here that the blower is bad but Im not really sure why I am getting the testing that I am getting. Ill take any advice at this point or a way to jump the motor to test it.

    Thanks

    OK answered some of my question. The blu/red runs thru the resistors to ground so it should be grounded.

      There is a connector there, with 2 wires, its the main power for the blower motor. If you connect just that one (without the other 2 connectors) it should turn on when you put the fan to an On position, and they key to Accessory. If it doesnt do that, it would appear to be the blower motor. If you give the bottom of the unit a wack with your hand and it starts, replace the motor, its bad.
