![]() If the refrigerant leaks out of the system, eventually, there won’t be enough left to cool your Trax. If you add too much coolant to your vehicle, you can cause more leaks in the AC system. The most common reason for your Chevy Trax’s AC not blowing cold enough is low refrigerant levels, followed by a dirty evaporator or condenser issues (bad or clogged). If there’s no voltage, test the resistor (YouTube). If voltage goes to the blower motor, it’ll need replacing. A simple test light will usually do the trick. We recommend testing the circuit for voltage at the blower motor first because it’s almost always easier. You can tell if the blower motor resistor has failed by testing for voltage where the harness plugs into the blower motor. Here’s how to test a blower motor with a multimeter (electrouniversity) Blower Motor Resistor Blower motor resistors come in many shapes and sizesĭepending on how your particular model year of Trax’s blower motor resistor question, it will still be able to turn on the blower motor when you turn the speed all the way up. If air starts blowing at full blast, suspect the blower motor resistor. If all the dash lights are on, the climate control system looks like it should be working, and no air moves, you should suspect the blower motor.īefore replacing it, turn the fan up to its highest setting. Bad Blower Motor (Most Likely)īlower motors are known to fail without warning. If you don’t hear any noise coming from the blower motor, the air conditioner not working check these two items. However, there are a few less common reasons as well. When there’s no air flowing through the vehicle’s cabin, a bad blower motor usually causes this scenario. If your Chevy Trax has no air moving through the climate system at all, that’s a lot easier to diagnose than the air that is blowing not being cool enough. AC Blowing No Air at All Usually the culprit There are just too many variables otherwise.ġ. Knowing whether or not the system has a charge is vital to a proper diagnosis.When the cooling system is suddenly not blowing cool enough, check the condenser up front for debris (quick and easy).No air moving at all is usually a bad blower motor.The other two deal with air temperature, and there can be quite a few causes for a failure to cool condition. The first section, not blowing air at all, is pretty straightforward. Jump straight to the one that best describes what is going on with your Trax. This article is broken down into these three sections to help save you time repairing your Trax’s broken AC system: There are A LOT of issues that can cause your vehicle’s air conditioner to fail. If your Chevy Trax’s AC system is not working, it can be uncomfortable and downright dangerous on a hot day.
