Blower motor replacement

That is my first guess, the resister. Check that first. If it doesn't fix it, check for problems with relays. Here is a guide to check the blower motor and resistor with instructions in the diagrams below to help show you on your car.

Check out the diagrams (Below). Please let us know what you find.

Find the blower motor it should have a blue and black wire going into it? If so direct power from the battey to the blue wire-did the motor operate-let me know asap.

here is the blower ACDELCO from Amazon for $76.00

Is the blower motor not operating at all? Or only operating at certain fan speeds?.. Let me know and I will be of better assistance.

You may want to first check the fuses/relays. Another issue may be the blower resister is faulty.

If you feel it is just the blower motor itself that is faulty, below are removal/installation instructions for the component.

REMOVAL:
Remove the right closeout panel.
Remove the blower motor wire harness connector.
Cut out the blower motor using a utility knife in the narrow groove of the lower case (FIG. 1)

FIGURE 1

NOTE: Cut through the case as straight as possible because the motor cup must be replaced.

In order to prevent damage to the component, do not cut any deeper than necessary to remove the motor cup.
Remove the blower motor.

INSTALLATION:
Install the motor blower seal. (FIG. 2)

Hope this helps..

Could be binding within the housing try banging around to free it. If its humming on all speed setting its getting power to it thru the blower motor resistor. Disconnect the blower motor and power it direct-let me know

If the module does need replaced than an estimate is below for that repair.

i suggest having a second repair shop look at it to ensure it does need the module replaced and not just a faulty relay or something else.

What does the unidentified item look like? If it is plastic, it may be a door has dropped from the HVAC case. This would explain the vent issue. Please provide a little more info, and I'll be glad to help. Doc

I will locate and send you an illustration of the HVAC controls and we will figure out where it lived - and a solution. Doc

Pretty much unplug it take the mounting screws out of it drop it down put the new one in mount it back up and plug it back in.
