The Most Common Problems With Having Low Refrigerant Levels In Your Car Ac I’ll assume you’re here because you added refrigerant, but your car’s ac still isn’t working. you want to diagnose and fix your car’s ac system yourself but don’t know what to do next. that’s what this article is about; helping you with a step by step approach. to find the root cause of the problem, you’ll need some special. Here are the tools you’ll need to troubleshoot your car’s ac problems professionally. you’re kidding yourself if you think you can diagnose car ac problems with just the gauge on a diy recharging kit. at the very least, you need to see the high and low side pressures and compare the readings to the outside and center duct temperatures.
How To Check Freon Level In Car Signs Its Low An ac diagnostic at a shop can cost as much as $400. however, with the right tools and tips, you can diagnose and fix your car’s ac yourself, saving a considerable amount of money. this guide will walk you through the essential steps to troubleshoot and repair your car’s ac problem on your own. Diagnosing car ac problems. 1. check the refrigerant levels. low refrigerant is a common cause of poor ac performance. you can check the refrigerant levels using a pressure gauge. if the level is low, it might indicate a leak, and you should consult a professional to locate and repair it. 2. inspect the condenser and cooling fans. The fans should turn on when the a c system is turned on. the easiest way to start diagnosing the problem is to turn the a c system on and watch or listen for the radiator or condenser fans to also turn on. you can do this without driving the car, but just have it running in your driveway. if the fans don’t turn on, the fans are either faulty. Step 1: to begin an ac recharge, start your car and turn your ac to max or high. step 2: the next step for an ac recharge is to determine if the ac compressor is engaging. an ac compressor is a device driven by the ac accessory belt that converts the refrigerant from liquid to gas. the compressor has a clutch at the end of it that should be.

Check where the hoses are crimped onto the fittings. check the schrader valves.check for pin holes in the condenser. check where the evaporator drains condensation with uv light. sometimes oil or dye can be seen. note: the dye check will not work if the system is too low and the compressor is not cycling. Attach vacuum pump: connect the yellow hose to the vacuum pump and turn it on. open manifold valves: open both the low and high side valves on the manifold. evacuate system: run the vacuum pump until a gauge reading of 29" hg (inches of vacuum) is reached. continue running the pump for 20 minutes.
