Does anyone know if the whole heater housing has to come out from the inside, or can the motor be removed from under the hood? Or is there anyway I can try & lubricate the bearing?
You can just see where the motor is by the firewall on the right hand side, from under the hood.
Looks like a big job! :uhoh:

Don't waste your time putting the piece you have to cut back on. Mine crumbled in my hands in places anyways.

I agree with b1lk1...don bother with the cover, it will crumble to pieces.

Thanks for the quick reply! I was afraid I was going to have to remove the complete htr housing from inside the vehicle!
It's in the middle of winter here in Canada, & I have to work outside, so I'll leave the repair until spring.
The other morning the htr was screeching as normal, (until it warms up then it's quiet.) I decided to try a quick fix!
I could clearly see the motor housing on the right side of the firewall under the hood. I carefully drilled a 1/16" hole into the plastic housing right in the centre of the heater housing, in the little bump where I thought the bearing might be. I then squirted a bit of 3 in 1 oil into the hole and ????
Instant silence!!! The motor has remained silent ever since. :smile:
I'll keep you posted how long the repair lasts!
