Ac not blowing hard enough thru the air vents.

2004 jeep grand cherokee 4.7 v8 4×4.
Ac not blowing hard enough, but the little air that does come out feels cool. I was able to see that the fan blower is turning counter clockwise. So i believe its blowing the opposite direction. After research online its a common problem. From what I read the Solution is to reverse a green and black cable that connects to the blower itself. I bet its an easy job but i dnt have much knowledge on electrical things. Does this sound like it can be the problem? Again the blower is turning counter clockwise.

Hi There,
It is usually very unlikely that the blower fan motor would turn counter clockwise unless you or someone else has purposely reversed the wiring to change the polarity. You may want to also check the air vent paths to be sure there is nothing impeding the flow of the air through the vents. I would suggest having a professional from YourMechanic come to your location to take a look at your blower motor.

The fan is what blows air in and out of your home`s vents. Lots of things can cause your blower to have trouble, especially if it gets too dirty. A fan clogged by dirt, a stuck wheel, broken motor, or a loose fan belt are all common problems that reduce the amount of airflow you feel coming from your vents.
Problems like a fan clogged with dirt, a dead motor, a loose fan belt or a stuck wheel can all cause your blower to not work properly. These problems can keep the blower fan from blowing enough air out of your vents to keep you cool. Your evaporator coil needs air to blow over it to complete your AC`s cooling process.
Nine times out of 10, weak airflow is caused by a clogged up cabin air filter. Over time, this filter catches all dirt and debris, which can build up and slow or stop the flow of air. It`s typically located under the dash on the passenger side or inside the glove box and should be cleaned or replaced regularly.
Here are some of the most common causes of why air doesn`t flow out of your vehicle`s vents: Your air intake is clogged, meaning that air isn`t getting in from the outside at all or isn`t circulating properly. There is a blown fuse in the ventilation system. Electrical issues such as a bad relay.
Ideally, your system needs 400 cfm per ton (+/- 50 cfm) for proper operation and efficiency. So if we have a 2-ton system, you want about 800 cfm of airflow through your air ducts. If it`s 2.5 ton, you want around 1000 cfm, (2.5 x 400).
Weak Airflow from the Vents

There are a number of possible reasons why this is happening, including dirt and dust buildup, bad capacitor, and an aging motor. If your blower motor is dirty or has a bad capacitor, you can call in an HVAC technician to fix the problem.

air conditioner not blowing air from dash vents, but blowing air from side vents
ANSWER : A few different items can cause the air to not blow out of the dash vents. The most common are a blend door or a control switch. The best method for the AC diagnosis feature can be found in the vehicles owners manual. I recommend having your AC checked by a qualified technician, such as one from YourMechanic, to have the problem diagnosed and repaired correctly.

My heater is blowing air through the driver side air vents but is blowing cold air through the passenger side and rear console ven
ANSWER : Hi there:

Climate controlled vehicles have multiple electrical relays that open and close vents to maintain the desired temperature. In some instances, these relays can wear out overtime. However, it’s also common for debris to clog up vents (especially side vents) which may restrict the flow of cool air. The best way to determine why your AC is not working efficiently, it might be best to have a professional mechanic complete a AC inspection; so they can pinpoint the source of your issues and recommend the right repairs.

Ac compressor. Blowing hot air through front vents and cold air through rear vents.
ANSWER : It sounds to me like you have a blend door actuator problem. The blend door actuator is responsible for controlling the blend door. The blend door is responsible for blocking off air to the heater core when your air conditioning is on. I would recommend having your blend door actuator tested using the manufacturer’s recommended procedure. Once this has been done, a qualified mechanic will be able to inform you of whether the actuator will require replacement in order to resolve this issue. If you need help with this repair, YourMechanic offers a repair and diagnosis service preformed by a certified mechanic that will commute to your location to look inspect your heater and AC problem.

Overheats When Blowing Warm With Heat & AC But Not When Blowing Cold AC
ANSWER : Hello, thank you for writing in. There are so many different codes being triggered, that it is unlikely all of these systems are having issues at once. We need to focus in on the fact the engine is overheating at all. You will want to check the level and condition of the coolant and the overflow tank. If the level is full then you may have an issue with the thermostat, radiator cap, or water pump. These can all be tested and changed relatively easily. If the main cooling system is okay, you will want to look into the heater core and climate control module. For more diagnostic help, contact our service department to schedule an appointment.

everytime I turn my car on the ac starts to blow air even if I switch it off. it won’t blow cold air or heat.
ANSWER : Hi there. Based on your question and input, it looks like your AC control switches are damaged, causing the vents to activate even if the switch is not activated. This is sometimes an electrical problem, as it could be triggered by a damaged electrical relay. You might want to have a professional mechanic complete an AC is not working inspection, so they can determine what is causing this issue you’re experiencing and recommend the right repair.

Problem with AC/heater – 2005 Ford Explorer
ANSWER : Hello. The problems you describe with the front system may either be a faulty control switch or faulty vacuum motors for the air blend doors. The problem in the rear is likely the rear heater control valve, which regulates the flow of hot coolant to the rear heater core and air duct system. The clicking noise may be a broken vacuum motor for that valve (integrated in the valve).

I would recommend having a certified mechanic, such as one from YourMechanic, come to your location to perform an inspection of the heater and suggest the needed repairs.

Air conditioner blowing warm air. Heat blowing warm air. Neither hot or cold
ANSWER : If the A/C system is full and pressures are reading correctly, and the cooling system is in proper working order (thermostat opens, no overheating, etc.), then most likely the problem lies with the dash. The climate control head unit may be at fault. One or more blend doors behind the dash may be stuck or broken. If you’re unable to fix this issue yourself, consider YourMechanic, as one of our mobile technician can come diagnose the issue with your A/C firsthand and help you fix it accordingly.
