Why would the GMC climate control (dual control) on the driver’s side suddenly switch from air conditioning to heating on a 2004 Sierra 1500. The most common cause for this to happen is an issue with the driver’s side temperature actuator.
Where is the actuator on the GMC climate control?
If it loses its internal setting it can jump from hot to cold on its own or even go to heating when cooling is set. If this is the cause the actuator will need to be replaced. The actuator is located under the dashboard on the bottom of the heater box on the passenger side.

Why is my blower not working on my GMC Sierra?
When you switch to high,the blower motor relay coil circuit is grounded and voltage is now applied directly through the relay to the blower motor; bypassing the resistors. So, I would look to see if the relay is ok. It is a five terminal relay.
How can I Make my Chevy heater blower fan work?
You have a fan resistence it should work in high speed only or not at all check all fuses to be sure you should have a 30 amp for the motor and is the motor new or used try the motor at the battery first to see if working before going further You can’t post conmments that contain an email address.
Why does my Silverado Sierra have no fan?
The failure mode on these is one or two of the resistors blow and you end up with just a few of the fan speeds or as previously mentioned the connector burns up and you have no fan speeds. Powered by phpBB © phpBB Group. phpBB Mobile / SEO by Artodia .
What to do if your blower fan is not working?
You need a new resistor block, or just the thermal fuse. For this car you need a 192°C, 250V, 10A thermal fuse. If you have the same problem on your Vw Golf 4 / Bora / Skoda Octavia 1, the repairing method is similar. You need to dismantle the dashboard to reach the blower fan and fan resistor.
