Review on 🔧 Enhanced Performance: Cardone 73-70012 Remanufactured Relay Control Module (RCC/RCM) by Kevin Bigelow

Perfect fit for my 2000 3.8 Mustang and worked great. Just in time for summer, my air conditioner is blowing cold again. Obviously, this isn't the only part that can affect your air conditioner, but it is one of the parts that are more likely to fail. Especially if your car is older as the relay that controls power to the compressor has been constantly cycling on and off over the years and is prone to failure. Like every relay in this module. I considered buying a used CCRM but felt it was a much better choice since it was redesigned with new components. A used CCRM may work, but depending on the age of the CCRM, it's susceptible to the same glitches as the original. Here are some simple checks to determine if this is your problem. This is for a 2000 Mustang 3.8L, but basic troubleshooting is the same for most vehicles. If the check engine light is on, check the DTCs to make sure none of the codes are affecting AC.2. Check the continuity of the A/C pressure fuse (20 A) in the engine compartment fuse box with a multimeter (S fuse). fuse hood.gif3. Check fuses F2.2, F2.23 and F2.24 in the under dash fuse box with a multimeter http://diagrams.hissind.com/wp-content/uploads/2011/06/2000-v6-dash.gif4 . If all the fuses are good, use a wire or paper clip and insert them (one at a time) into both sides of the AC low pressure switch. I used solid bell wire stripped on both ends and slipped easily into the back of the jack. Make sure there is enough cable and that it fits in the connector. Start the car, turn on the AC and check for 12 volts on both sides of the switch. If there is voltage on only one side, the switch is defective or there is little freon in the system. In this case, remove the connector plug and connect it with a wire and see if the compressor turns on. In this case, turn off the vehicle and connect a pressure gauge to the low-pressure AC connector. I have actual pressure gauges, but you can buy an inexpensive pressure gauge and a can of AC as a unit for less than $20 that will allow you to check the pressure and add Freon if needed. Start the vehicle without removing the low-pressure bridge. The compressor must be running to check the pressure.5. Check the high pressure switch in the same way as the low pressure switch.6. If the low pressure and high pressure switch test passes, connect a 12V jumper directly from the battery to the A/C compressor. The plug has only two wires, a black one that is grounded. Jumper 12V to another wire. Again I used a long bell wire stripped at both ends and slipped easily into the back of the jack. Start the car and touch the other end of the cable to the positive battery post and see if the A/C compressor turns on. If this is the case then this is an important check as it will confirm that the compressor is working properly. I didn't ground the black wire to the battery, but I would if the compressor wouldn't turn on.7. The CCRM is located under the front fender on the passenger side. Remove the front bolts securing the fender and remove the fender. You don't have to remove it completely as it is flexible and can be peeled off and pushed aside. Disconnect the wire harness from the CCRM, then unscrew the CCRM bracket. Connect the wire harness to the CCRM. Use stiff wire or a paperclip (I had to use a paperclip) to test pins 12 and 24 on the CCRM for 12V. With the car running and the A/C on, if there is voltage on both pins, that's a good sign. Then ground one end of the long, solid cable to the battery and thread the other end through the hole in the fender. It must be long enough to fit into pin 22 of the connector. I used a paper clip and stuck it into the back of the connector and then wrapped the wire onto the paper clip. Start the car and turn on the air conditioning. If the compressor does not turn on, the AC clutch control relay in the CCRM is most likely defective and the CCRM should be replaced.8. Here are a few more things to consider. There is still a very small chance that the Power Management Module (PCM) could be the cause of the problem, but a faulty PCM will most likely lead to many more problems than just AC. When you turn on the air conditioner, you should hear a slight change in RPM and turn on the cooling fan. These are also good signs as they indicate CCRM performance and PCM control.
