You mean the blower motor stops blowing air , the A/C compressor is still engaged ? The temp gauge shouldn't have anything to do with the blower motor .But stranger things have happened on these systems when they are controlled by a electronic module (BCM )
The instrument panel cluster (IPC) displays the engine coolant temperature as determined by the engine control module (ECM). The ECM sends the temperature data via high speed GMLAN serial data to the body control module (BCM). The BCM then sends the information via low speed GMLAN to the IPC in order to display the engine temperature.
The BCM applies voltage to the blower motor through the HVAC relay. The resistors and the blower motor are in a series circuit. The following list represents the number of resistors in series with the blower motor per particular speed request:
• Low speed--4 resistors
• Medium 1 speed--3 resistors
• Medium 2 speed--2 resistors
When the operator requests High speed, the HVAC control assembly applies ground directly to the blower motor through the high blower motor control circuit.
Do you know anything about automotive serial data communications ? GMLAN Is general motors version of C.A.N controller area network .
Do you know anything about diagnosing automotive electronics ? Using a digital volt ohm meter ? Using wiring diagrams to pin point locations in a electrical circuit for testing ? Do you know what a factory componet location diagram is ? It takes more then looking at fuse's an relays , to see if current is flowing in a electrical circuit .

Then click the search button , then click the first blue link . This is the blower motor control diagram . Do you know how to read a wiring diagram ?
That is the heater / AC blower motor ! There are electrical circuits and relays and blower motor resistor , blower motor etc... Electrical testing is the way to diagnose blower motor circuit . Looking at a wiring diagram to see what controls the blower motor on your particular vehicle would be the first step in diagnosing your problem . Do you know how to do automotive electrical testing , how to read or follow a wiring diagram ? Videos on youtube show how to test blower motor and related parts and wiring . Blower Motor and Resistor Diagnostics by Wells
Kill switch for what ? Fuel pump ? It doesn't matter there isn't one on GM vehicles . Do you know how to do basic automotive electrical circuit testing . If not suggest you go on youtube an watch some videos on trouble shooting electrical circuits , how to test GM fuel pump relay circuit , how to read a wiring diagram . Know how to diagnose be for replacing parts ,
I don't know why your question is bound to this special breaker.
If your question is common, the wye/delta is a way to reduce the starting current of a large three phase asinchronous motor. When a three phase motor is first connected in wye (star), the starting (peak) current is about 3 times less than this in delta. When already in motion the electromotive force will make the peak current when turned in delta much less, than that with a stopped motor.
Here's a link to the online manual.
As far as that diagram....didn't you label the wires?
Take a look here, it may help you. circuit wiring , especially the paragraph that begins: "Knowing that electrically common points have zero voltage drop between them is a valuable troubleshooting principle." Also read about resistors. That speed control knob is one.
Hope that helps...
