Clutch Cycling Switch– AC systems use an electromagnetic clutch to activate the compressor.

Here are the four main reasons why your Equinox’s may not be working: Faulty CompressorĪ faulty compressor will not move the refrigerant through the system properly. If the cooling system works better on the highway (where fans aren’t needed), your Equinox may be having fan issues (blown a fuse, bad motor, wiring harness damage). If your condenser has taken damage or is clogged up, it can’t remove the heat from the refrigerant.Ĭheck to ensure that the electric fan over the condenser is engaging. Check the condenser to see if it’s blocked by debris. Weak airflow to it will reduce its efficiency. Bad CondenserĪn AC condenser is a little radiator that pulls the heat out of your vehicle’s refrigerant. It can be tempting to get more coolant and get back on the road, but unless you find where the leak is coming from, it’ll eventually happen again. In fact, most compressors won’t even cycle on without the right amount of refrigerant pressure (this saves them from eating themselves).Ī low refrigerant level is perhaps the most common reason that your Equinox’s air conditioner is not blowing cold. Your Equinox’s air conditioner will not work if the refrigerant level is too low. Here are the most common causes of an AC system not blowing cold in the Chevy Equinox: Lack of Refrigerant There’s a section on each below.Ĭhevy Equinox Air Conditioning Not Blowing Cold: Causes

If only one heater gets hot and the other doesn't, then the coolant isn't flowing through the heater core.

First, is the engine coolant full? Second, if you have the engine running and the heater on, do both heater core hoses get hot? If they do and the coolant is full, chances are the blend air door is the issue.

Based on your description, it sounds like the blend air door actuator is going bad.
