Noises and smelly blower motor

Postby C3LOS » Fri 21.07.2017, 18:58

Hi all. I have recently noticed a noise and light burning smell when I turn my heater on from 0 to 1.
It also makes the same noise when the air on is switched on.
Looking at a few posts on LEC and further investigation on my car, it seems to be coming from my blower motor....so needs to come out so I can check it (and empty it of what I think could be the start of a mouse nest)...did have mice in the garage but not anymore!!!!!

I have removed the ECM and the mounting bracket attached to bottom of the blower motor without taking the enter fascia assembly off (don't really want to do this as it's a reasonably big job)
Is there a way of removing the blower motor from the assembly in situ (i.e. 3 bolts as in the attachment) as there seems to be a rigid harness in the way towards the top of the motor?

Any help would be much appreciated

On a LHD car it's a super simple job: you just have to remove the glove box to gain a better access (not even sure it's required though) and then the connector, and finally the three screws. No need to remove the ECU or anything else.

Yes of course, but I do think it's easy too on the RHD cars, because someone told me here that it was an easy fix before I fixed mine.
And it was most probably a RHD owner! :D

If it were my car I'd put the top down, get the engine warmed up, turn the heater control up to 4 and turn the fan speed on max. Leave for 20 mins and see if the smell has gone. If not, investigate further

PS if you park up in a garage for any length of time always put some mouse traps on the floor baited with some tasty milk chocolate :wink:

Well finally got the motor off and as I thought they're was a mouse nest there!
Poison has now been placed adequately in my garage! Now time to put it all back together!!

Last year our bathroom xpelair started making a horrible noise like the bearing was gone. I bought a new one, but when I removed the cover to start the swap-over I found a blue tit. The noise was the fan impellor hitting its head. It was dead.

Didn't smell, though. :-D

The exhaust side of the extractor fan in my bog always smells outside.
