3-5 Reasons Why Your Car’s AC Broke And How You Can Fix It

The dog days of summer can linger on to be unbearable and uncomfortable when your car’s AC decides to go on the fritz. Before you are ready to throw in the towel and take the car to an automobile professional, there are a few things to check on to get you feeling the cool breeze from your car’s AC.  These tips are great for a do-it-yourselfer car enthusiast.

Take It To The Max

While the car is safely in park mode, fire up the engine and turn the AC dial onto Max.  A light should be visible to ensure that the AC is turned on high. If the light begins to blink or does not come on at all, it is a definite indication that there is a potential problem with the AC.  Look at the fuses and wiring to troubleshoot any issues that could be causing the malfunction.

A malfunction with a fuse needs to be re-checked after repairing to ensure that the AC is functioning properly.  A malfunction with wiring can be picked up on a digital code reader.  A certain code will go off depending on the issue with the wire.

Unclog The Pipes

Like a human beings, the delicate mechanical parts of a vehicle don’t run properly if there is a system malfunction.  If the AC does not feel cool or sounds a little rough around the edges, it may be time a check for blockages in the cooling system.  Assess the bumper, grill, air filter, and condenser for any kinks or blockages that can prohibit strong air flow.  Clear the parts of any debris that has collected and recheck the AC for maximum air flow quality.

Buckle On Down

An automobile has different belts that serve many functions.  For example, most cars are equipped with a specific belt for the AC compressor.  When the AC is on the fritz, make sure that the belt is in proper working order. The best time to check if the belt is working properly is when the car is not running. With the car turned off, pop the hood and locate the AC belt. A loose belt can cause a malfunction with the AC.  Evaluate the situation with the belt.  Make the necessary repairs to get the AC back in business.

Stop, Look And Listen

When your car’s AC is not up to par, there is a chance that the compressor may not be up for the challenge.  With the engine running, crank up the dial on the AC.  First, listen to make sure that the blower motor is in full force.  After checking on the blower motor, focus on the compressor.  There is a clutch mechanism on the compressor that operates a pulley to keep the compressor running.  Normally, the compressor will go through on and off cycles.  Unfortunately, a problem with the compressor will be evident when the compressor does not run at all or will shut off quickly an on cycle.  If a problem with the compressor is detected, AC fluid replacement needs to be done.

Plug Up The Hole

Underneath the hood of the vehicle are pressure points that monitor the function of the AC.  When the pressure points are out of whack, the AC will not provide the cool comfort you are in search of on a sweltering day.  These pressure points serve as a clue that a leak may be present.  Most leaks occur where the condenser is.  Typically, the leak is created because debris and other elements get lodged or propel against the grill that is positioned near the condenser.  Sometimes, leaks can start at a pipe or fitting.

After a leak has been detected and repaired, the car will require another re-check.  This re-check needs to include a full replenishment of necessary fluids.  Sometimes, a thorough flush of the system may be required to ensure the proper replacement of fluids is sufficient.
