Ford Climate Control

With no snow, ice, and frigid temperatures to deal with, summertime driving is supposed to be pleasant and easy. Most of the time, it is – except when you can't stay cool. A broken air conditioning system is one of the most unpleasant and frustrating experiences you might have on the road in summer. Furthermore, a non-working part can cause the surrounding parts to work harder, which in turn leads them to burn out faster than they should.

Because the cooling system is made up of many moving parts, AC problems can range from a quick and simple fix to a more serious problem. Since it's not always easy (or possible) to figure out an AC problem on your own, your best bet is to bring your car in for service by an expert mechanic, like you'll find at Grapevine Ford. While you might not be able to fix the problem yourself, here are some symptoms to look for that will help your mechanic understand where the problem is starting.

What if the air conditioning system only blows warm or hot air?

After a few minutes of turning the AC on, the system normally blows out air at the desired temperature. If you find that the air doesn't get cold, or gets just slightly cool, there may be a problem with the system's condenser. The condenser is a component that intercepts refrigerant fluid as it enters into the AC system. The refrigerant fluid starts out warm, and the condenser normally cools it off before sending it into the cabin. If the condenser doesn't work correctly, however, the refrigerant fluid won't get properly cooled. This can happen if one of the condenser components stops working, such as the coils or fans. The coils help cool the fluid, while the fans blow the normally cold air into the cabin. A defect with either part can prevent cold air from reaching you.

What does it mean if the AC unit blows no air at all?

Sometimes, the AC system fails to blow air through at all. This can happen for several reasons. One possible cause is if there is a mechanical problem somewhere in the system. There are a number of components in the AC system, including the expansion valve, compressor, condenser, evaporator, and tubes. Additionally, the components have many fans and blower motors, which can burn out and stop functioning. The fans and motors might stop working if they break, but they can also become clogged with dirt or dust particles. In that case, they just need a thorough cleaning to start working again. Your vehicle may also be equipped with a safety device that shuts down a component in the AC system if it's not working correctly. Some cars also have a sensor that makes the entire AC system turn off if the pressure is too low.

What causes the AC system pressure to drop?

Ford Rear Climate ControlsA drop in the AC system pressure can signal a more serious problem. One common cause for low pressure is inadequate levels of refrigerant fluid in the car. This sometimes happens in the spring, and it's due to the fact that your car can use up to 15% of its refrigerant fluid during the winter time. That's more than any other season! Other times, a crack in a valve, seal, hose, or condenser can cause a refrigerant fluid leak.

A fluid leak can be detected by the presence of an oil puddle beneath the car. A mechanic can also diagnose a leak in the AC system using special black light dye, which shows where the leak is starting when it's illuminated beneath a special light. Since leaking refrigerant fluid can get into the engine and cause damage, it's best to get a leak fixed right away.
