Chevrolet Repair: rear AC blower, fuse blocks, screw driver

Question
I have a 2004 GMS Envoy XL, same as Trailblazer. The rear AC blower will not blow. All fuses are good in front and rear fuse blocks. Ther is a fuse next to the blower in the passenger side rear. When I pull the fuse then reinsert it the blower comes on for approx 3 seconds then turns off.
Would this be a faulty blower control module?

Answer
HI TOM, THE FIRST THING I WOULD DO IS GET AT THE BLOWER MOTOR, GRAB YOURSELF A TEST LIGHT AND CK FOR POWER AT THE BLOWER MOTOR PLUG,I HAVE SEEN SOME BURNED CONNECTIONS AT THIS AREA..BUT IF WHEN YOU ARE THERE AND THERE IS NO POWER THAN I WOULD SUSPECT A FAULTY MODULE..SOMETIMES BY REMOVING POWER AND RETURNING POWER LIKE YOU DO WITH THE FUSE IT JUMPS THE MOTOR ENOUGH TO START IT. IF YOU DO FIND POWER AT THE MOTOR ALSO CK FOR GROUND,IF ALL CKS OUT GOOD HERE,HIT THE MOTOR WITH A SCREW DRIVER HANDLE AND SEE IF IT STARTS LIKE THIS. [FLAT SPOT ON THE ARMETURE] IF SO MOTOR IS BAD..IF YOU NEED MORE INFO GET BACK TO ME,PLEASE WHEN YOU LEAVE THIS SITE WOULD YOU RATE MY ANSWER,GOOD OR BAD..THANK YOU ,,,TOM..
