5.9 Diesel - garaqge stored in Interior Alaska so AC not used in winter. I had it looked at and was advised the TIPM was bad. I'm trying to figure out how this could be as the TIPM looks like a fuse box to me. All systems appear to work nomally just no cold air.

Re: AC does not work
The TIPM is a "totally integrated power module" and controls several items on the vehicle. The fuse box that you are looking at is the TIPM. It can cause the a/c to be nonfunctional. However, with out actually looking at your vehicle I cannot say if they are correct in their diagnostics.

use a 10/40 petrol/diesel synthetic oil and change every 6000miles with a oil filter every third oil change .if in alaska or norway then use a 5/30 in the winter ,for more temperate climes use the 10/40 ,here in spain in the summer i use 20/50 for my jaguar
Sounds like you have a bad fuse, and or maybe a bad relay in your dash panels. Start by looking up the fuses that affect your sunroof, then work out to the other issues. On my Ford, there is a bad relay that affects my power windows, my radio, and my interior lights. Sometimes more than one fuse is related to a system, so check all the fuses before trying relays.
Hello, Thank you for letting me assist you. Let's look at your problem. I don't see a year or model for your vehicle so I will assume it is 1990 or newer. Manufacturers for some reason setup the defroster setting to activate the AC compressor regardless of what you have the temperature setting set to anytime it is turned on. This becomes problematic in some regions. I know when I drive through Pennsylvania during the winter I had to change my windshield washer fluid from cleaner to a 50 /50 mix of cleaner and alcohol/deicer fluid in order to stop the icing on my windows. Your problem though, as I understand your post, is there is ice forming on the inside of the vehicle.
The first thing to make sure you are setting the air control to recirculate instead of bringing air in from the outside. Second, make sure your using a 60/40 mix of Anti-Freeze in your radiator and that your radiator is properly filled. Normally you use a 50/50 but in your case you seem to be in a colder region and being a little stronger on the Anti Freeze will ensure you don't have a motor freeze. Next you need to check your thermostat. If you haven't replaced it in the last 5 years I would replace it. In colder regions you really need the thermostat to make sure your actually building heat up before water is cycled from the radiator. The next check is to make sure your actually getting heat to the heater coil on the inside of the vehicle. Start the vehicle and let it idle for about 10 minutes. This should be enough time for the engine to heat up and for the thermostat to open. Then turn the heater on with it set to your mid-level vents. If you have no heat coming through the vents you need to check your heat control valve and AC compressor. If your set to heat and not defrost the AC compressor should not be running. Make sure the control valve on your main heater line is open. The main Heater line is a 1" or 5/8" line that runs from motor to the firewall, it will have a control valve on it that is either cable controlled or more commonly vacuum controlled. The vacuum controlled system are more problematic as any vacuum leak in the system will cause it to malfunction plus the vacuum controller where you set the temperature inside the vehicle can cause problems and is hard to isolate. The good news is you can by-pass this control in the winter even if you only do it for testing. Remove the controller and put a straight pipe in its place. If you don't have water running through that hose either your water pump is bad or you have a blockage. Now, assuming you have water flowing through that hose, if the heater works when the vehicle is sitting and idling but it gives you trouble when your driving there is one more option. I don't recommend doing this except in very cold climates as it can cause you to overheat and you have to remember to undo this trick when it gets 50 degrees or warmer. You can partially block the radiator. Be careful not to fully block it and be aware this will cause more resistance when the vehicle is moving. They sell kits in cold climate areas that are made of canvas to partially block the air flow through the radiator but you can make one using cardboard or a piece of canvas just don't use anything plastic. This will reducing the cooling capacity of your radiator and increase the warmth of the water going to the heater core. I normally see these in areas like Canada, Colorado or Alaska in the winter but there are cases when you may need them in other states. Let me know if this doesn't fix the problem. If none of this works then let me know what you found doing the checks I gave you and we will look at something else.
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.
this is going to sound kinda stupid but i had the same problem with my 88 earlier this winter . It could be as simple as water in your fuel. the solution would be to put HEET in the tank. I prefer the red can unless you have a diesel. I live in interior alaska and if you let your tank get below a half it will condensate inside. This sounds to simple to be true, but if you live in a cold climate it makes a big differance. Water will make it run like ****.
dodge decided to do away with the fuse box that was located on the interior of the vehicle ( I also have a 2006 2500 diesel) there is on one fuse box located on the drivers side fender well under the hood this box is called a (TIPM TOTALLY INTEGRATED POWER MODULE) all power is distibuted through this box. this box is controlled by a computer with a softwear system.
