Remove the blower motor relay. Disconnect blower motor. At the blower motor connector, check for continuity from the BN/OR wire to the battery negative post (or a verified frame ground). Likely it will show zero ohms or low impedance (a few ohms)

If true, likely there's is a short somewhere along the length of the cable BN/OR wire to chassis.

Comment for further assistance.

Question corrected for clarity.

The Passenger Compartment (steering wheel) box does 2002 to 2007 according to these. HOWEVER, although the same layout, so do different things depending on the year like this one.

Cavalier radio removal

sounds like u have a whole in a turbo boot the sound u r hear is the turbo trying to **** air through the whole in the boot

No you have to find out which wire is the hot 12v to the old radio. and connect it to the red 12gage wire coming from the new radio. also you could try buying a connection plug from circuit city so there is no wire cutting involved, also the old fuse could be blowen.
