Hi,

Can anyone provide any insight on blower motor replacement on an '84 E150? I've managed to locate the blowermotor (under the dash in front of passenger seat) and remove the hardware. At this stage the wires are holding it in place and they run through a grommet that doesn't seem to come out. Anyone with experience with this that could explain how I'm supposed to remove the wiring from the old motor and re-wire the new one?

Thanks

 

This goes back a bit,
Check carefully if that rubber grommet may be a plug in connector.
If not ,pay attention to colors and if no difference make sure ,if you can, as to which direction the motor turns when facing the squirrel cage attached to the blower motor shaft.
You can always cut the wires and connect the replacement motor insuring it rotates in the same direction (clockwise/counterclockwise). It helps if you have a long T handle allen wrench to loosen the set screw holding the squirrel cage onto the motor shaft Make sure you set the blower wheel (squirrel cage) the same distance from the housing and shaft end. You should confirm the motor responds as the blower settings require. When the motors pulled excessive current they had a tendency to cook the contacts and connections on the blower motor switch. worth checking for excessive heat damage
.Did the motor quit working altogether or was there another reason you are replacing it?

 

Thanks for the info, I'll check this out when I get home. Replacing it due to loud squealing noise coming from it, would still turn, but obviously not well. I think splicing the new wires to the old and soldering is our game plan after sleeping on it. Will update.

 

It it is squealing , it is pulling more current and that can load the switch assy and create some damaging heat and the push on connectors get hot and corrode and then get hotter until the connections on the switch just won't take any more and melt Good move to at least check them .
