2. The 4 by 100 relay and the 4 by 400 relay.
Under the hood in the aux relay box number 1, it will be marked C1008 and its the larger of the two relays on the left side of the box........
The CCRM is a set of 4 relays in one module. The relays are : 1. Relay for the PCM (Powertrain Control Module) 2. Relays for the high and low radiator fan speeds. 3. Relay for the fuel pump. 4. Relay for the Air Conditioning clutch on the compressor.
Check all of the following................. 1. Freon level in system. 2. Pressure switches and relays. 3. Controller head. 4. Power and ground going to the compressor clutch.
Check all of the following................. 1. Freon level in system. 2. Pressure switches and relays. 3. Controller head. 4. Power and ground going to the compressor clutch.
Check all of the following............... 1. Freon levels. 2. A/C compressor clutch, coil and harness. 3. Pressure switch. 4. Control panel. 5. Sensors and relays.
most of your relays should be located under the hood. on the 93 Nissan there are 2 black boxes, 1 is behind the battery and the other is located at the front drivers side, near air filter. the tops of boxes should have description of fuses and relays inside. hope this helps!
Here are many air compressor out there, and all of them have up and downs. The air compressor need a tank to compress air and for a nail gun a 1 gallon compressor may not do the job because the compressor is constantly compressing the tank, a big compressor will take up more room. For a small job you may want a oil free compressor $100~200, for a large job you may want a $300~500 oiled compressor.
The air conditioner/compressor sits on the front passenger side on top of the fender. Remove the water reservoir and then you can disconnect and remove the air compressor. I do not know yet how to remove the air dryer as I cannot see how to remove the air lines from the dryer. I did remove the dryer from the compressor though, by removing a single screw then turning the 1/4 turn and pulling it out of the compressor....so at worst I will be able to put my new compressor in with the old dryer.
A standard air compressor hose is on average about 25 to 50 feet in length. These hoses are typically 1/4 of an inch in width but sometimes 1/2 inch too.
The compressed air discharged from an air compressor is hot (fig. AC1-1). Compressed air at these temperatures contains large quantities of water in vapor form. As the compressed air cools this water vapor condenses into a liquid form
Under the hood near the air compressor. it is mounted to a bracket on the rh side. it will look like a square box aprox. 1 inch square. 2 Relays will be mounted side by side will be green or brown at the base with a black plastic upper cap portion.
Check the following.......... 1. Power and ground to the compressor clutch coil.. 2. Pressure switches and relays.. 3. A/C -heater controller.. Without the year, make and model its very hard to narrow it down..
