My AC will no longer turn on unless you are pressing very hard and continuously on a specific spot near the AC dial.My mechanic said it might be an HVAC problem or something electrical. Before this, the AC would work, but only on Max AC.
Sounds like you are having a problem with the a/c control unit. On some vehicles the switches are separate, but on most it is a complete unit and must be replaced as such. The unit can develop internal connection issues causing it not to run the a/c. Problems like these are not typical but they do occur. A certified mechanic will help pinpoint the problem with your a/c. Checking the unit and the wiring is important to make sure the unit is in fact the faulty part.

Reasons a Dodge Stratus AC Isn`t Working. The most common reasons a Dodge Stratus ac isn`t working are a refrigerant leak, an electrical climate control issue, or a problem with the air conditioning compressor. You may not realize there`s a refrigerant leak until the air conditioner stops blowing cold.
Dirty air filters are usually the most common problem that air conditioners face. Faulty motors are another common issue that air conditioners face and that can impact the cooling system. If the AC stops cooling suddenly, the thermostat should be checked.
Your car`s air-conditioning stopped working most likely because of a freon leak or a bad compressor. While these causes may be the simple to spot reasons that your air-conditioning isn`t cooling in your vehicle, a dirty cabin filter or a bad belt could also be the problem.
AC Works Intermittently: When the air goes from cool to warm to cool again, you`re experiencing intermittent problems. This is often due to a clog in the system, a failed compressor or compressor clutch, a faulty condenser fan, a clog in the system, or the actuator directing airflow has failed.
Dodge Ram climate control reset instructions
Step 1: Turn your fan to the lowest possible setting. Step 2: Hold down the climate control/conditioning button for 10 seconds. Step 3: Let go of the button, then press and hold it again until the lights on the button start flashing. And that`s it!
You might be low on refrigerant or have a worn out motor or a dirty evaporator coil. Not all AC problems demonstrate themselves with loud sounds or funny odors coming from your system. Some of them simply reduce the AC`s ability to run, and all you notice is less cool air in the house.
The most common causes of broken air conditioning leaks or compression issues. If you are feeling cool — but not cold — air, the issue could be a clogged filter, a problem with the cooling fan, signs of radiator trouble, or it could simply mean it`s time to recharge your AC.
Check to see that the cooling fans on the condenser or radiator are running when the air –conditioning is on. Look for any restrictions like leaves, bugs or dirt that would keep air from passing over the condenser. Check the cabin air filter to ensure that it is not clogged.
Your car`s AC stopped working most likely because of a freon leak or a bad compressor. Though these causes are the simple to spot reasons for your AC not working inside your car, it might be anything as simple as a dirty cabin filter or a bad belt.
Look for it first around on the exterior of your machine, especially along the bottom edge near the ground. An AC`s reset button is typically red and visible, so it should be easy to spot. If you don`t see a reset button on the outside, it could be located inside the unit behind the service panel.
Your air conditioner`s internal circuitry needs some time to reset after you turn it back on. This can take approximately a half-hour, so sit tight for about 30 minutes. Turn your air conditioner back on at the thermostat. After 30 minutes have passed, turn your air conditioner back on at the thermostat.
After turning off the circuit breaker linked to the AC unit, wait for a full minute. Set a timer for 60 seconds and then return power to the AC unit. As a safety precaution, it may be a good idea to inform everyone in your household that you will be resetting breakers.
Here`s the thing: It`s normal for your AC to run continuously during hot summer months. You see, on extremely hot days—we`re talkin` high 90s to 100s—your system needs to keep up with the incoming heat. To do that, it will run longer in order to maintain a constant, desired temperature in your home.
Air leaks and poor insulation are a common cause for making your house feel hot, even when the AC is working, as they can allow the air your air conditioner has worked so hard to cool to escape, leaving your house hot. Humidity can interfere with your thermostat`s ability to track temperatures and also traps heat.
A car A/C blowing hot air is often the result of a refrigerant leak. Refrigerant is a liquid that circulates through your car`s A/C system, expanding and contracting as it removes heat and humidity from the cabin. None of the other A/C components will function correctly without proper refrigerant levels.
When an air conditioning stops blowing cold air, it`s typically because the thermostat is set incorrectly or was altered. Children often play with thermostats they can reach. If this is the case, simply reset your device.
Generally speaking, when cool air blows during early morning hours, and then blows warmer as it gets warmer outside, it can be due to a few possible sources. First, and most common is that the AC vent is set to draw air from the outside and not through the cabin.
This can be caused by an electrical fault in the A/C compressor circuit or the magnetic clutch that drives the compressor. Another cause could be an internal obstruction inside the refrigerant circuit that is preventing refrigerant from circulating inside the A/C system.
If, on inspection, you hear chattering, whining, squealing, chirping, or rattling sounds coming from the AC compressor, it is time for AC service.
A car`s air conditioning should be recharged every two years or so. However, if you notice any signs that your AC needs to be recharged, it`s important to take your car in as soon as possible. Taking care of your car`s AC is important for several reasons.
The short answer is yes, coolant can affect air conditioning performance in a number of ways. Typically, coolant can affect your AC`s temperature, humidity, and airflow. Your AC`s temperature may be affected by the proximity of your car`s interior to your engine.
Some air conditioning systems have a reset switch, which is a small, red button. Typically, the button will be on the outdoor unit. If you have a problem locating it on the outdoor unit, you may find relevant details on the equipment`s manufacturer`s manual. Press the red button for three seconds and release.
The HVAC control board is where the thermostat wires connect to your heating and cooling system. In most cases the control board can be found at your furnace or air handler.
The method to reset your thermostat will vary depending on the model. Common methods for resetting a thermostat include installing the battery backward for five seconds, pushing a recessed reset button with a pin or paper clip, or shutting off the breaker to the thermostat for 30 seconds.
