Question about 2001 Chevrolet Silverado 1500
Temp control stuck: whatever the setting when starting the vehicle, the temp will stay until vehicle is turned off and sometimes longer, usually in a couple of hours or next day. So if you set the temp to hot then try to set back to cold, boom! the air stays on hot! I have already changed out the ac/heater panel switch control.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Mine has always done this. As far as I can tell it is just Engaging in anticipation of a Person wanting to change the Temp. Computer Signals it to do this.

Have you checked the cowl to see that it is free and clear of leaves and dirt? You may have to take the plastic off to get down into it and sweep it out with a vac. Usually it is right under your wipers.

You have dual zones that are controlled by temperature actuators the passenger side has lost its memory or has gone bad you can put it in self programming by disconnecting the battery for ten minutes then hook it back up start the truck turn the temperature control on but do not touch any other controls let it go thru the self programming for about 6 to 7 minutes then select your temperature you want if it still does not work properly you may have a bad actuator or a bad connection at the actuator

Make sure the radiator pressure cap is the correct one and that the hose is not soft--check the lower hose and heater hoses for softness as well. They should be firm, but not hard or cracking. The temperature sensor is reporting normal operating temperature, so it and the thermostat are working correctly (hot water would blow out of the radiator if it were stuck). Check the cooling fan for free turning and no noise. Check it's grounding connection. Check the fuse box for blown fuses to the fan and to the A/C compressor. Make sure all the relays and fuses are firmly pressed into their sockets. Check the A/C compressor clutch winding for resistance--should not read infinity. Does the blower motor for the heater/A/C run when either is turned on? The A/C switch on the dash may be defective.
