Heater Blower Motor Replacement Continued.
This picture is important. I spend a good 20 mins trying to move the orange clip to unlock the power plug. WRONG. After nearly breaking the connector, I grabbed a mirror and took a good look at the power plug. See the X in the picture. Push there to release the plug. A mirror is a good thing to have handy. It's really tight in there.
New blower vs. old blower motor. The power connector is on a wire on the new motor. It makes it much easier to plug in.
Here is the new blower motor. There are two rubber plugs on the replacement motor. Only remove the the smaller plug. There is a bypass hose which plugs in here. It must be used the keep the motor windings cool.
You can see the blower motor plugged in. The air bypass pipe is visible here. That will plug into the hole in the picture shown above.
All bolts in and the wire harness clipped back in place. The new blower sounds as quiet at the old one. I don't know if I could have cured my problem by just spraying some lube into the open bearing port in the old motor. If you have one, you should try that first. If I get 8 years out of this motor like I did the first, I'll still be pretty happy with my decision.
Everything back in its place. Looks like a pro job!
Here is a close up of the oil port on my old motor. Right in the center of the spindle.
You have to bend a few metal tabs to get the housing off. The spindle on the end was very dry. That may have been where the noise was coming from. Hope this information helps you with your blower problems.
