Fortunately, there are things you can do before wounding your wallet
It’s January and that time of the year when outdoor temperatures hang around the 30 degrees Celsius mark. Inside the car is even hotter. Unfortunately, your AC has been acting up. During the cooler December days, you possibly did not have too much to worry about. You simply lowered the windows and cruised. Now, however, you fear you will be hit by the mother of all heat waves if you try that. Possibly, there is also too much dust swirling all over and you do not want to get involved. If you cannot handle the heat, then get out to a garage, and get your AC fixed.
Most problems with the air conditioning system are best left to experts with the knowledge and proper equipment. There are, however, a number of problems that you can check out yourself. See the table.
