Chevrolet K1500 Suburban A/c Heater Control

Diagnostics and Quick Fixes for Your Chevrolet K1500 Suburban A/C Heater Control

A truck is only ever as reliable as the parts that comprise it. Now, while an internal component like the a/c heater control in your Chevrolet K1500 Suburban does not directly contribute to fantastic performance nor does it give extra boosts of power, it's still one very important component to keep tabs on-lest you get left out in the cold-literally. The difficulty with internal components like the a/c heater control is that they're neither visible nor is it a simple task to notice any defects with it. There are some things to look out for-you just really need to be vigilant.

Not enough heat nor cool

The first and most visible sign of wear or failure of your a/c heater control is the most obvious: the air conditioning does not heat or cool properly. By "properly", we usually mean that it doesn't work at all. Now, this indicator is not an exclusive symptom of a failure with the heater control-other culprits could be a lack of Freon, a failure of the a/c clutch, or a busted blower. It does give you an excellent indicator and reminder to include the a/c heater control in the inspection as you seek out the specific component at fault.

You'll know that it is, in fact, the heater control at fault when the most vulnerable components of the control-like the blend doors, the motor, or the cores-are inactive or show visible signs of damage. These parts can survive on quick fix replacements-like replacing or jury-rigging the hinges-but at this stage, it's safer to consider replacement.

Erratic air distribution

Another sign to look out for that more specifically tags the a/c heater control as being at fault is when the above symptom is accompanied by inconsistent output from the air conditioning unit. The two symptoms together isolate the problem by eliminating other parts that will manifest only one or the other. Again, the erratic distribution of air from the unit is due to damage with the components that make up the heater control.

One quick fix, is to review the fault codes that are stored in the heater control-as reference when taking it in for repairs-or, if you're up to the task, upgrading the software of the control if it is computerized. Analog heater controls are somewhat easier to quick fix because parts are available in used car shops or discount parts bins.

  • How to Keep Your Chevrolet K1500 Suburban A/C Heater Control in Excellent Shape

    Even in a tough ride like the Chevrolet K1500 Suburban, the a/c heater control is an extremely important component. Ask anyone living in a state with really cold winters-or warm summers, for that matter-the a/c heater control manages both. As with any part, the heater control can wear out over time. What you want to do is take care of it to make sure that it lasts you a long time. After all, you wouldn't want to ever need it, and be unable to use it! Here are the best tips you can follow:

    • Use air conditioning properly.
    • One of the things that quickly wear out the a/c heater control much more quickly is keeping it at full blast and highest (or lowest) thermostat for an extended period of time. It over-exerts the heater control-not to mention the air conditioning system as a whole. Keeping the thermostat and blower at moderate levels is, in fact, enough to extend the service life of the heater control considerably.
    • Keep it clean.
    • Yes, you can clean the a/c heater control. But, no, don't just chuck a pail of soapy water on it! You can actually damage it far worse that way. The proper way to clean you Chevy's a/c heater control is to wipe it down carefully with a damp cloth. Flannel is a good material for this because it is guaranteed no to be abrasive on the surface of the heater control. Avoid using solvents that are too strong as they might possibly damage the a/c heater control.
    • Test run air conditioner every few months.
    • The suggested way to do this is by switching it on and testing the blower and thermostat from the lowest possible setting, and then working your way up. Give ample time for each 'step' along the way to engage and process a change. This will help you to gauge the state and status of your a/c heater control. It is easy to diagnose problems with the a/c heater control-and even the air conditioning system as a whole-via this very simple and practical test.
