Remove the lower blower motor cover retaining screws.
They should be 7mm bolts, not screws. If you click "View Full Image" on the images above, you'll get a larger, close-up view. I've given these directions before to several other customers with great success.
Tell you what... I will opt-out and forward you to another Tech who may better assist you. Sorry for the inconvenience. Sit tight one sec, some will be right with you...
Ok, there was a slight change in design. The plugs you see are what are called heat stakes and have to be cut off with a chisel. The new blower motor is supposed to come with 2 retaining screws that will be installed in their place. Give me a minute to upload full procedure
Ok, below are full directions:
Important: Cut through the case as straight as possible because the motor cup must be reused. In order to prevent damage to the component, do not cut any deeper than necessary to remove the motor cup.
Notice: Refer to Fastener Notice in the Preface section.
Tighten Tighten the nuts to 2.4 N·m (21 lb in).
Tighten Tighten the screws to 1.8 N·m (15 lb in).
I am another expert. Did you not read my two posts explaining that there was a slight design change and that there are 2 HEAT STAKES(plastic rivets) that you have to cut off with a chisel?
Here is the post again:
The design change was mid production and so not all manuals show this, and not all 2005 cobalts are like this. some have the plastic rivets and some have the bolts
Do you have any other questions on this since getting the new directions?
