| Subject: | Poor Heater Performance |
| Models: | 2015-2016 Chevrolet Colorado |
| 2015-2016 GMC Canyon |
Condition/Concern
The customer may state the heater blows cold air. The technician may find that relearning the HVAC doors may eliminate this concern for a short time. Upon inspection the technician may find a cracked or broken shaft on the temperature valve.
Recommendation/Instructions
Remove the temperature actuator and inspect for cracks. If the shaft is cracked in one place, install a #4 hose clamp over the temperature valve shaft as shown below. It is not necessary to remove the door to add the clamp. If the shaft is cracked in more than one place or a piece is missing, the temperature valve must be replaced.
