The reason your car isn’t blowing cold air is because your car is losing refrigerant gas. So first you will need to find your refrigerant leak.
To find and fix your AC leak, here are the steps you will want to take:
- Start at the compressor and follow the hoses coming up.
- You may see an oily substance on one of the hoses. This is because your air conditioner contains both refrigerant and refrigerant oil. When there is a leak, oil will leave a trail on the hose, most often in the place where the leak is located.
- Once finding the leak, you will need to locate the hose that you will need to remove and hook up a set of air conditioning gauges to it. You will then use a refrigerant recycling machine to collect the old refrigerant, but if it has all leaked out you will not need the recycling machine.
- On-bolt both ends of the hoses, and it should easily pop off. Then follow the hose down to the compressor to remove that bolt as well.
- You will then need to get your new hose and lubricate the O rings with some AC oil.
- After lubrication, snap the hose back into place and bolt it in.
- You with then need to use a vacuum pump to vacuum the system out for about an hour. This will get rid of all the moisture in your AC system.
- After it’s done vacuuming, you will need to add refrigerant. On the top of your car hood, it will typically tell you how much you will need to add.
- You will then need to use a digital scale to see how much you are adding. Start your car and turn you AC on full blast until it reaches the designated amount.
