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.
How to identify a faulty car AC?
If your car’s air conditioner isn’t working, there are a few things you can check to troubleshoot the problem. First, make sure that the air conditioner is turned on and that the temperature setting is correct.
Also, check to see if the air conditioner’s filters are clean. If the filters are dirty, they may be blocking the air flow and preventing the air conditioner from working properly.
Finally, check the air conditioner’s compressor to see if it is working properly. If the compressor is not working, it will need to be replaced.
Why does my car’s AC randomly blow hot air?
There can be many reasons for this problem, as we’ve identified so far. So any of these problems are not ones that can be repaired on your own, and you will need to find a repair person for the job.
Problems in the electrical systems.
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.
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.
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.
How to fix the AC blowing warm air?
There could be a few reasons for your AC unit to be blowing warm air. One reason could be that the unit is low on refrigerant. Another reason could be that the air filter is dirty and needs to be replaced. Finally, if the unit is simply malfunctioning, it will need to be repaired or replaced.
How much does it cost to fix a cold AC in the car?
The cost of fixing a car’s AC can be expensive because the AC system is made up of many different parts, and each part must be working properly for the system to function correctly. If one or more parts are not working properly, the entire system may need to be replaced, which can be costly.
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. This could be caused by a dirty filter or a leak in the AC system.
Why Is My Air Conditioner Not Turning On?
There are several reasons why your air conditioner may not be turning on. The most common reason is that the air conditioner is not receiving power. Check to make sure that the air conditioner is plugged into an outlet and that the outlet is working.
If the air conditioner is plugged in and the outlet is working, the air conditioner may be tripped.
Check for a switch near the air conditioner that may have been accidentally turned off. If the air conditioner is still not turning on, it may be low on refrigerant.

Why does the fan blow cold air in the car?
There could be a few reasons why the fan is blowing cold air in the car. One reason could be that the car’s coolant levels are low and need to be topped off. Another reason could be that the car’s thermostat is not working properly and needs to be replaced.
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.
