SOURCE: bypass ac compressor 2006 dodge ram 3500 5.9 L

The easiest method to do this is to go to an auto parts store and buy a belt designed for a truck with no air conditioning. The belt will be the right size, and you just install it as normal, and bypass the compressor

SOURCE: A/c compresor quit blowing in

2006 Dodge Ram 2500 Diesel 5.9 Cummins

There is no relay. The pressure sensor sends signal to PCM, then the PCM sends signal to the TIPM or total integrated power module which is sort of self contained fuse box but really a micro computer that controls many things. The Module has had known issues that can affect one of many things. I lean to bad module. Here is the diagram for compressor.

tdisline_749.jpg The Integrated Power Module (IPM) is a combination of the Power Distribution Center (PDC) (1) and the Front Control Module (FCM) (2). The PDC mates directly with the FCM to form the IPM. The PDC is a printed circuit board based module that contains fuses and relays, while the FCM contains the electronics controlling the IPM and other functions. The IPM is located in the engine compartment, next to the battery and connects directly to the battery positive via a stud located on top of the unit. The ground connection is via electrical connectors. The IPM provides the primary means of voltage distribution and protection for the entire vehicle.
The molded plastic IPM housing includes a base and cover. The IPM cover is easily opened or removed for service access by unscrewing the cover retaining nut and has a fuse and relay layout map integral to the inside surface of the cover. This IPM housing base and cover are secured in place via bolts to the left front fender support assembly.
Replaceable components of the IPM assembly are broken down into the following components:

  • The Power Distribution Center (PDC)
  • The IPM cover
  • The Front Control Module (FCM)
  • Complete IPM assembly that includes all three parts
All of the current from the battery and the generator output enters the integrated power module via a stud on the top of the module. The integrated power module cover is removed to access the fuses or relays. Internal connections of all of the power distribution center circuits is accomplished by a combination of bus bars and a printed circuit board.

SOURCE: 2007 dodge 5.9 diesel, ac

is the condensor fan working? also check the pressure on the system, high pressure due to low coolant level or insufficient air flow through the condensor will shut the system off. also the pressure transducer may be malfunctioning and not allowing the compressor to come on.

Where I find AC.fuse/Relay on dodge ram07 2500 6.7

George, I am pretty sure the compressor relay is built in to the TIPM (Totally Integrated Power Module) on the 07. You may have to have a tech. with good scanner check the TIPM/relay. Fuses should be marked on the under side of fuse box cover. Check the attached links,instruction and guides, Good luck

2000 dodge 2500 diesel 5.9 automatic ac compressor doesnt turn on

ac systems require a certain pressure to function at 15 years you more likely have lost pressure. you will have to hook up ac gauges to see whats up , if you have sufficient pressure then you can look for electrical issues , clutch, pressure switch, fuses,relays etc.

2007 Dodge 2500 5.9 diesel. When you turn on AC you can see clutch try and engauge and after 3-4 tries it stops. No AC. If drive around for a while AC starts to work after engine heats up?

Working same problem today on my 2006 Mega Cab Diesel. 2 possibilities. Either the compressor clutch coil is going bad ( totally integrated power module tries to engage it a couple of times, senses the coil resistance is wrong and shuts down) or the TIPM (Total Integrated Power Module) is bad. I'm leaning toward clutch on compressor but still have testing to do to isolate. Could be both, but I doubt it. New TIPM is about $900 it appears from what I read. New compressor is cheaper. May be able to replace just the clutch coil for even less but reading mixed results. Good luck.

On my 2007 Dodge 2500 diesal the AC clutch will not engage. I found the fuse box under the hood and there is only one 10 amp fuse that says hvac. so where is the clutch relay or fuse? Which big fuse...

there is no relay in that box that is called the tipm or totally integrated power module. that module is controlled by a computer and should be checked with a scanner to see if you have a code for the a/c. i m having the same problem i have been told it could be low freon but can not get the clutch to engage to check the high and low pressure. Also read where it may be the diode in the clutch on the ac compressor if you have a multimeter probe the compressor a good compressor will read somewhere between 3.5 and 4.0 anything else and clutch needs to be replaced. other possibilities may be the high or low pressure switch on the line. on myh 2006 2500 diesel it is located near the plug for the compressor on bottom side of motor. hope this helps.
