When the Front AC Blows Cold and Rear AC Blows Hot, the back escalator is where your issue is. The air box with the heater core, all the blend doors, and a little a/c accumulation device must be divided in the truck’s back.

Along with it, a brass expansion valve (identical to the front orifice tube) will be included. You can either pull the old one off and clean the small screen that is on the upper side of it, or you can go to Napa and buy a new one for $30. because a plug will be used.

Just to let you know, separating the air box is the difficult part; dealing with the expansion valve is simple. Additionally, you can complete all of this without removing the rear heater core. It took me two weeks to figure out what was wrong with mine, but now it freezes up.

Your car may be spewing hot air due to an electrical problem if all the AC components are in good operating order.

An apparently healthy air conditioner may become inoperable due to a frayed wire or blown fuse. The first step in identifying and fixing an electrical issue is to thoroughly visually inspect the fuse box and wiring in your car.

Damaged compressor.

The compressor powers the AC system in your car. It is in charge of moving the refrigerant around the system. The antifreeze won’t be able to cool the condenser if this component is malfunctioning.

Defective condenser

The refrigerant absorbs the heat and humidity that your AC system removes from the cabin. The condenser’s job is to maintain the refrigerant’s coolness so that the cycle can continue. The method fails if the condenser isn’t functioning properly. A burst of hot air strikes you in the face at that point.

The average cost to repair a car’s AC unit is $200-$500. However, if the AC unit is not working properly, it may need to be replaced, which can cost up to $1,500.

Why does my car’s AC only get cold when I accelerate?

There could be a number of reasons why your car’s AC only gets cold when you accelerate. One possibility is that the AC compressor is not engaged when the car is idle, but kicks on when the car’s speed increases and the engine RPMs go up.

This could be due to a problem with the AC compressor clutch or a low refrigerant level. Another possibility is that there is a blockage in the AC system that is causing the air to flow more slowly through the system when the car is idle.

Why does my car’s AC get warm when I stop?

The airflow over the condenser (the heat exchanger in front of the radiator), which is more prevalent when the automobile is moving as opposed to when it is stationary, is crucial to the system’s operation.

Condenser fans will automatically turn on to maintain airflow when the car is in stop-and-go traffic or is entirely stationary.

Why is my car’s AC not cold when idling?

There are several potential reasons why your car’s AC might not be performing as well when idling as it does when driving. One possibility is that the AC compressor is not engaging properly when the car is idling.

Another possibility is that there is a problem with the AC refrigerant level, or there could be a problem with the AC compressor itself. If your car’s AC is not cold when idling, you should take it to a qualified mechanic for diagnosis and repair.

Why does the AC only work when the car is moving?

The AC in a car only works when the car is moving because the air conditioner is powered by the engine. When the car is not moving, the engine is not running, and there is no power to run the air conditioner.

Why Is My Air Conditioner Not Turning Off?

The most likely reason your air conditioner is not turning off is that the thermostat is set to “cool” instead of “off.” If the thermostat is set to “cool,” the air conditioner will continue to run until the temperature in the room reaches the set point on the thermostat.
