DIY Auto: Intermittant A/C. Compressor clutch diagnosis on a 1990 Jeep Cherokee.
This apparently is a common problem with these A/C compressors. Symptoms are A/C works when things are cold. When things warm up, the clutch fails to engage. I've had this jeep for most of its life and this has always been a problem. In the early stages, turning the engine off/on would get it to work. Then moving the dash control to vent and back would get things going. Now, a mallet to the compressor housing engages the clutch but only briefly. Not a solution but proof of where the problem lies. I by no means am a professional mechanic but I thought by making this video it would assist other non-professionals help diagnose their intermittent A/C cooling problem. When you are done watching my video, another member here on YouTube shows you how he removed his shim; http://youtu.be/V_s8AOqEMgw





AC Clutch Repair and Noise Diagnosis -EricTheCarGuy
This one starts out as a noise diagnosis that ends up working in an AC clutch repair on a 1998 Acura 3.2 TL. In addition to the AC compressor clutch, we also talk about repairing the AC belt idler pulley and other possible noises during AC operation. So if you ever need to replace an AC compressor clutch or have a noise coming from the idler pulley on your AC system, this video is for you. Here's some useful links.

How To Find and Repair AC Leaks - EricTheCarGuy

Keep in mind refrigerant is a CFC meaning that it pretty much kills the ozone layer and if you don't respect that you WILL cause environmental damage even a little adds up so please follow the precautions in this video when working on an AC system. The other thing about AC is that it involves a lot more than just shooting a can of refrigerant into the system when it's not working right there are many systems that come into play that you need to consider such as; the health of the cooling system, cooling fan operation, the mechanical operation of the components of the system, the operation of the HVAC inside the dash, and the electronics so keep in mind if you're having a problem with your AC it could be much more than just a simple leak.

Automotive HVAC Pressure Diagnostics
Automotive HVAC Pressure Diagnostics... LINKS: http://www.autodiagnosticsandpublishing.com/TransTS.html http://www.autodiagnosticsandpublishing.com/CBT_Auto_Traning.htm Pressure analysis diagnostics is the cornerstone of properly doing a climate control system assessment. As we all know, the HVAC systems is composed of a high and a low pressure side. The orifice tube or expansion valve is the one components in between these two refrigerant conduits. The compressor of course is the one in charge of pressurizing the refrigerant. Pressure analysis is by far the best, and probably in many cases, the only way to properly diagnose the dozens of specific issues with the automotive HVAC system. But first, here are the various scenarios relating to pressure analysis. Before we go into it, it is important to understand what the baseline pressures should be. The normal HVAC baseline is about 39 PSI on the Low-Side, and about 250 PSI on the High-Side. How far away we deviate from this baseline, is what's going to determine our issue. Here are the different analysis scenarios. Case 1... High pressure on the Low Side and baseline pressure on the high side. This may translate to say about ...

Auto Air Conditioning Systems at a Glance
Auto Air Conditioning Systems at a Glance LINKS: http://www.autodiagnosticsandpublishing.com/TransTS.html http://www.autodiagnosticsandpublishing.com/CBT_Auto_Traning.htm Automotive Air Conditioning came about in the 1940's. Since then, technologies such as computerized automatic temperature control, which allow you to set the desired temperature automatically, have added a great deal of complexity to today's modern air conditioning system. Also we now have tough environmental regulations that regulate all tasks, such as recharging the system with refrigerant, evacuating and charging the PAG oil needed by the compressor. Al this due to scientific studies, that have proven the damaging effects of refrigerant to our ozone layer. Today's automotive technician is required to be certified to purchase refrigerant, and repair your air conditioner. The shop must also incur the cost of purchasing expensive dedicated equipment that insures the capture of these ozone depleting chemicals. Basic knowledge of your air conditioning system is important, as this will allow you to make a more informed decision on your repair options. Modern air conditioning or HVAC systems are composed of the following, COMPRESSOR, CONDENSER, EVAPORATOR, ORIFICE TUBE, EXPANSION VALVE, RECEIVER DRIER, or ACCUMULATOR. If your car has an Orifice tube, it will not have ... Get the whole story right here in this video... Enjoy...

This unit is composed of three parts, the clutch plate, the hub and the coil. The clutch coil is the one that creates an electromagnetic field around it, which attracts the plate and engages the clutch. The plate is also linked to the drive or serpentine belt and is driven by the crankshaft. The hub and the plate have to be calibrated to a specific gap using a feeler gauge. The purpose of this video is to illustrate how almost all AC compressor clutches are wires. The actual wiring may contain other components, such as transistors and IC computer chips, but the control itself is the same. In all cases, these extra components are used to control the relay coil, which in itself controls the AC compressor clutch. This simple circuit can also be used to wire an older vehicle due to lack of parts and high costs. Here is how this circuit works. This circuit has one relay, a refrigerant pressure switch, and a micro switch. The micro switch is a W O T or wide open throttle switch used to disengage the compressor clutch during wide open throttle conditions. This is done to protect the compressor from damage at high engine speeds. Electrical current flows from the 12 volt power feed to the fuse. Then current flows to terminal...

A C Switches
A/C pressure switches are pretty straight forward. They are both, electrical switches and pressure transducers. Their purpose as electrical switches are to interrupt the circuit. There are many, many different arrangements that these switches can be configured in an electrical system. So, always be sure to review the diagram for the system you are working on.





A/C CHARGE GONE WRONG DODGE RAM 1500 AIR CONDITIONING COMPRESSOR DAMAGE PROBLEMS
Now I learned the hard way that this method of filling up the a/c can be bad for the a/c-system if you do it the wrong way like I did. My mistake was that I overfilled the a/c. After I did this video the ac compressor was first clicking and then rattling really loud so that I decided to unplug it and go to the shop and get the system vacuumed out and refilled properly. I was lucky that no seals were damaged and no parts needed to be replaced. So be carful if you use this method of rerilling your a/c. Next time my ac refrigerant is low I will only add the amount of r-134a just so that the air coming out in the vents inside the cab is cold again, not more.

A/C Compressor Not blowing cold air , Clutch Engaging, A/C Recharge
A/C Compressor clutch engages shuts off in just a couple of seconds, Freon Charged to the max... A/C Compressor Out of a junkyard but looked recently installed. Have not changed the dryer... I know I should.. Need to see of there are any possilble small leaks i dont know about.. But A/C worked like a Glacier before the compressor blew... I dont think the compressor may be bad. But then again.. Does anyone know what to look for when taking apart compressors? Please help. Thank you !
