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 ?
Do you know how to do automotive electrical testing ? How to read an use a wiring diagram ? Do you have manual or automatic climate control ? Automatic has a control processor (electronic )
You would need to take Rear Quarter Trim Panel off- Right Side (TrailBlazer, Envoy, Bravada) To get at the blower motor for testing electrical circuits . This video i have posted is for the front blower motor , you test the AUX . blower motor the same . Blower Motor Problems Auto Repair Help
It could be several thing's, fuse's , circuit breaker's , broken wire's inside the rubber boot from the car body to the door , this happens a lot on older vehicles from opening the doors over the years . The drivers door is the master switch . You need to find what fuse's , circuit breaks Power these systems . You can find that info. here http://bbbind.com/free_tsb.html . check for B+ voltage with a volt meter at the door switch an also check grounds . There are videos on youtube - basic automotive electrical trouble shooting , how to read wiring diagrams (if you don't already know) . I'm looking at a wiring diagram now , I also see that a BCM - body control module is shown on the diagram . Do you know what a BCM is ? You can google it .In automotive electronics, body control module is a generic term for an electronic control unit responsible for monitoring and controlling various electronic accessories in a vehicle's body. Typically in a car the BCM controls the power windows, power mirrors, air conditioning, immobilizer system, central locking, etc. The BCM communicates with other on-board computers via the car's vehicle bus, and its main application is controlling load drivers - actuating relays that in turn perform actions in the vehicle such as locking the doors or dimming the salon overhead lamp. If you are not familiar with these thing's your best bet would be to take your vehicle to a qualified repair shop that does .
Check the circuit breaker on the bottom left corner of the machine. It is under the machine. You may need assistance lifting the laminator a few inches to get your fingers under it. Push on it and listen or feel for it to click. If it continues to open after you plug it in then you may have a problem with the machine electronics. I also have had weak circuit breakers that needed to be replaced.
Each heat shoe has a small thermal fuse, if either fuse is blown, the laminator keypanel will not operate. 99% fix everytime, just follow the wires from each heat shoe (right side of laminator) cover off. Ohm each set of wires and look for an open circuit. replace fuse (TCO) and it will work everytime...... Westco Laminating Service 405-324-6092
