From the sight glass on the dryer tank, it can be observed that when the air conditioning is operating normally, if there are continuous and slow bubbles in the sight glass, it indicates insufficient refrigerant. If there is obvious bubble flipping, it means the refrigerant is severely insufficient. Add refrigerant.

As a long-time owner of the Cadillac SRX, I've encountered similar sudden air conditioning failure issues. This is usually caused by several factors: First, insufficient refrigerant or leakage – you can check the AC lines in the engine compartment for oil stains; Second, compressor failure – listen for abnormal noises when starting the car; Third, fan malfunction or blockage – poor heat dissipation also affects cooling; Fourth, blown fuses – check the AC-related fuses in the fuse box; Fifth, electrical issues like relay damage. My troubleshooting experience suggests starting with the simplest checks – fuses and fans first. If those are fine, then test refrigerant pressure, and visit a professional shop for refrigerant recharge or part replacement if needed. For prevention, regular AC system maintenance can reduce such problems. Don't ignore minor issues – they may damage core components over time.

As a regular in the car enthusiast circle, the non-cooling issue with the Cadillac SRX's air conditioning is really frustrating. Recalling the last time I dealt with a similar situation, the causes were varied: refrigerant leaks are the most common, especially during the high temperatures of summer; if the compressor is seized or the belt is loose, it won't work; don't forget to check the fan, as a clogged condenser can lead to cooling failure; also, check the fuse, located in the fuse box near the driver's seat, to see if it's blown; a faulty temperature sensor could also be the culprit. I recommend starting with some basic troubleshooting: confirm the AC temperature setting is correct, then check if the fan is running. If that doesn't solve the problem, take it to a shop for pressure testing and electrical diagnostics. Don't just add refrigerant randomly—if there's a leak, you'll be wasting money. Regular vehicle maintenance can save you a lot of trouble in the long run.

When the air conditioning in my SRX is not cooling, I usually start with the simplest troubleshooting steps. It could be due to insufficient refrigerant, causing the system to malfunction; a faulty compressor may produce unusual noises; a malfunctioning fan can reduce cooling efficiency; check the fuse box for blown fuses; or poor electrical connections like loose plugs. My approach is to first check the air conditioning settings and fuses, then see if the fan is operating normally. If the issue persists, I recommend taking it to a professional repair shop promptly to check the pressure and refill the refrigerant. Remember not to delay to ensure safe driving.
