I have been trying to find this drain now for 3 days, searching the web, asking on forums, called 2 Dodge dealers (can't believe they did not know for sure where it would be), crawled under my car and looked everywhere for it, pulled the carpet along the fire wall and I have still not found it. No vertical hose or elbow, no horizontal hose or elbow, no just plain nipple, but it has to have a drain somewhere. If you know 100% for sure where it is please, please let me know. I need to unclog it so the water from the A/C can start draining again.

It's driver me crazy not being able to find this thing.


Thank you, thank you, thank you

How air conditioning works:

Auto Service: Air Conditioning, A/C

The air conditioning system in a 2008 Dodge Nitro is serviced when freon gas gets low or when the system does not work.

How often should service be performed:

A recharge of the AC freon gas will not be required until the car has quite a few years or miles. Usually this becomes apparent when the air blows hot from the vents. A fully charged system should reduce ambient temperature downwards of forty degrees. As the air conditioning system ages freon will seep out through small leaks where parts are joined together and sealed with rubber o-rings (a circular gasket). These o-rings begin to dry out and cannot give an air tight seal. The system will still reduce temperature even with half the freon required, just not as well. Therefore as a vehicle ages, a recharge of the system every three years is normal.

What are the symptoms of faulty Air Conditioning:

If this recharge lasts a short period of time, there is a more significant leak which needs to be diagnosed and repaired. Usually, one of the lines, the condenser or the evaporator will develop a hole where the freon will leak much more rapidly. The air conditioning system will also not work if a component has failed mechanically. The compressor is the most common failure item. The pulley on the compressor is in constant motion, even when the air conditioning system is not in use, and will wear out over time. The compressor also contains the most moving parts within the system, so breakdown at some point is expected. In newer cars with advanced climate control, sensor and computer problems are quite common. If a sensor stops working or if it measures incorrectly (either pressure or temperature) the system will stop working.

How air conditioning works:

Air conditioning provides a large amount of comfort when driving. Ambient temperatures and heat generated by the engine can create a very uncomfortable cabin for passengers. Air conditioning does not provide cold air, instead when the system is working well will take the heat out of the air inside the cabin. The freon under high pressure will pass through a valve either called a thermal expansion valve or an orifice tube, which allows the freon to rapidly expand. This drop in pressure creates a drop in temperature. The freon then passes through tubes in a radiator looking device inside the cabin called an evaporator core. The air inside the passenger cabin is pushed through this evaporator core before it exits the vents and has the heat taken out as the freon seeks to regain surrounding temperature. This process also takes all the humidity out of the air in the cabin(think of the evaporator core as a cold can of soda with condensation). This process of drying air also makes the defrosting of the windows in the winter time much easier. The air conditioner will be active when defrost is commanded even with the heat running. This will take moisture out of the air and quicken the defrost of windows.

What can happen if this service neglected:


Neglect of the air conditioning system can lead to some problems. For the most part, a non-functioning air conditioner means no relief from high temperatures and humidity, and accordingly this lack is more problematic in areas of the country where sustained high temperatures are common. However, in colder climates, lack of air conditioning will cause longer times to defrost or defog windows before driving safely. In some cases, mechanical failure may lead to other problems in the car. A seized compressor can break the serpentine belt and leave the car without a power steering pump, an alternator and a water pump. Finally, freon is an ozone depleting agent. Any leaks in the system are detrimental to the environment.

HOW TO CHANGE THE Nitro EVAPORATOR

I HAVE A 2008 DODGE NITRO HOW TO CHANGE THE EVAPORATOR ON A 2008 DODGE NITRO


1. Disconnect and isolate the negative battery cable.

2. Recover the refrigerant from the refrigerant system..

3. Partially drain the engine cooling system.

4. Remove the nut (2) that secures the A/C liquid and suction line assembly (1) to the A/C expansion valve (3).

5. Disconnect the A/C liquid and suction line assembly from the A/C expansion valve and remove and discard the O-ring seals.

6. Install plugs in, or tape over the opened refrigerant line fittings and the expansion valve ports.

7. Disconnect the heater hoses (4) from the heater core tubes. Install plugs in, or tape over the opened heater core tubes to prevent coolant spillage during housing removal.

8. Remove the nut (6) that secures the HVAC housing assembly to the engine compartment side of the dash panel (5).

Bypass AC Compressor on 2008 Dodge Nitro v6 3.7L


Published on Jun 5, 2016

82.5 Belt Required

I used a Dayco 5060825 Belt for 2008 Nitro with 3.7 v6 motor....other years with same engine will probably work.

Modified Diagram Here: http://i66.tinypic.com/2w33ul0.png

Originally broke down 2 hours away from home and spent hours at an auto parts store. I wanted to make a video to save someone time in case this happens as there is no documentation of an AC Bypass for this Nitro on the net. I put the old belt and AC Compressor back on so that I could record this. Idea was taken off of a forum for a 3.7L Jeep close to the same year.

How to Find an Air Conditioner Leak

How to Find an Air Conditioner Leak


HOW TO FIND AN AIR CONDITIONER LEAK IN 10 MINUTES!

Aug 2, 2016
This is a video tutorial on how to detect a leak in a refrigerant system for an automobile. We used a Freon sniffing tool which is available here for around 25 dollars https://www.amazon.com/gp/search/ref=...



If you would like to read about how to do this in more depth here is a link to a written article: https://www.2carpros.com/articles/air...




Leaks

Leaks are the most common problem associated with the air conditioning system.

If pressure is low, then there may be a leak.

Using a UV A/C leak detection kit is the easiest way to find a leak.
Follow the instructions on the packaging to introduce UV dye to the system and UV light to find the leak.
Check around all fittings to verify that they are all secure.
Check hose manifolds on the compressor.
Check the front seal and the o-rings sealing the pressure switches on the back of some compressors.
Check where the hoses are crimped onto the fittings.
Check the Schrader Valves.
Check for pin holes in the condenser.
Check where the evaporator drains condensation with UV light. Sometimes oil or dye can be seen.

Note: The dye check will not work if the system is too low and the compressor is not cycling.

How to Replace a Nitro Expansion Valve


Jun 11, 2019
Dodge Nitro expansion valve in this Jeep Nitro. Recharge AC system with 2 cans of freon, AC now freezing cold. And yes you should do a vacuum on the system to help remove air and moisture but I was in the parking lot of walmart and had to wing it as is.
