Check the ground wire going to the compressor ! Test for power by using the frame as a ground rather than the ground in the ac harness . I tied in a wire from the harness ground and ran it to the ground on the battery and Shazam it works great !!
Had the same problem in my 2006 4.7 V8, it was the PCM of all things. It was an easy fix actually. Plug and play PCM for about $250.00-work like a charm. Sadly, I have so many other issues with this struck.
These trucks have so many problems I have to remove my dash again to rebuild the AC/Heater box again, I still have not gotten the AC to work correctly, I will not buy another Dodge truck, I know that if any of you have a problem with this the first thing you need to do is take a test light and make sure you are getting power to the AC compressor if there is no power then your TIPM is bad, if you hard wire a switch like I did also install an electric fan and wire it also to the AC switch you install that way the system will not over heat. if your TIPM goes out like mine did the system will not Communicate with the fan in other words when the system starts to get hot it will not turn the fan on to cool the condenser causing the system to over heat and blow out the freon out of the overflow valve. I will post another video soon to show all of you how to correct this problem with out spending a lot of money.
i had the ac won't turn on problem. high side switch, but my problem was the aftermarket line wasn't drilled through to the port. So when i replaced my ac compressor, and everything with it. all my troubles started.
hey do you have a link to the cut off valve? or measurements/specs? also any tips? im gonna do this method rather then pulling the dash out. Thank You.
Make sure you call first for the TIPM, they sent me the wrong one. Also change the Fan clutch. What ever parts you buy make sure you're buying Dorman brand if you buy anything else you're buying junk. Hope this helps.
@@leokarras6243 already replaced fan clutch got power to button but no turn on did clutch check on compressor still good turns on with added power gonna check the high low switch located on top of compressor but my electric fan not working was wondering if they both wont work because of switch
Not sure what brand you're buying. If the parts that you are buying are nor made by Dorman then they will not work correctly. Buy OEM parts for your truck anything else will not work and if it does it will not last. I suggest you Google the parts and buy them online you will save a lot of money that way.
I got them from air hose Source in Bloomington California they have five locations I believe they're half inch to 5/8 they have both I think I put half inch in my car and 5/8 in my Dodge
Leo Karras yeah I measured the hard line goin into the engine, it’s 5/8 so I just ordered a barb valve. Did you put the other valve next to it on the hose closer to the passenger side? There’s not much room there, so that’s why I ask....thanks!
I fought mine. I also added a switch to kick on the A.C. compressor. this I causded by the TIPM. I had mine replaced for 600. And only the dealership can do it
Hello Jason I am not sure what TIPM is but like I said I out a switch in mine and also 2 cut off valves on the heater core and it blows cold now I went threw all the work to replace all the blend doors and truly if any one reads this I suggest you simply install 2 cut off valves like I did and save your self the trouble of replacing your blend doors, also on my I only had 1 blend door bad and it was the passenger door all the other doors were fine.
Leo Karras TIPM or totally integrated power module. soon you will loose trailer lights. rear windows will quit. I am going to put shit off valves on my heater core. I can get it to blow 55 degrees down the highway. 61 idle.
I am glad I posted here I hope no one goes threw what I did but if they all watch the video and read these comments we all can save a lot of money in repairs, I will look into that TIPM, and you will get much colder air once you install them valves, install 2 of them not just 1. If you install 2 you will feel the difference like I did also anyone that reads this that has a problem with there blend doors if they also install cutoff valves like I did will not have to go threw the trouble in replace there blend doors, Have a great weekend, Leo.
Leo when you mention "shut off valves" youre talking about installing one on the inlet and outlet hoses of the heater core, right? Just want to clarify this and thank you.
its best to do 2 of them. after I made this video I installed another one and I was getting much colder air, these trucks have a problem with these system I think it's truly a bad design but an easy fix, I removed my heater box, if you do this you will not have to replace the blend doors in the truck. best of luck to you with it.
The problem is the fuse box these trucks all have that problem I forgot the name if it, what happens is if you do what I did and install a switch it will work but the system will over heat if you are sitting with the AC on you will what sounds like air loss that is the Freon blowing out of the over ride valve when the system gets hot the high pressure switch will not turn the fan on. I leave mine on when I am moving when I am a stop for a few minutes I turn the compressor off, that fuse box is not cheap used about 600.00.
I have a shop we work on Semi's not cars or trucks what is wrong with you truck? it is a lot of work it will take all day do you have the blend doors? what is your truck doing? is the compressor working? after rebuilding the whole system on my truck nothing changed it still does not work correctly I need to change the TIPM I ordered one and when it comes in next month I will change it, what I would do if I was you is install 2 cut off valves on the heater hoses that way it will work no matter what. it will save you 10 hours of work, let me know what the problem is with the truck.
Can you tell me what your truck in doing? I may have some time next week towards the end of the week and be able to help you, I have to tell you to be careful where you take the truck this can be very costly I have had so many people contact me and we were all ways able to resolve the problem. I replaced and rebuilt the whole system on my truck myself and the problem was the tipm there has been way too many as you can see that have had the same problem.
I never found the problem, I have a friend that I called on it he told me that the 05, and 06 had a wiring problem and the wire harness had to be replaced, also I had a problem after I did that, the system would over heat and blow the Freon out if I was in traffic and not moving, I found that problem also, I changed the fan clutch and it solved the problem, I think you should also install 2 cut off valves on the heater core, I did that and I get much colder air but the right side is not as cold as the drivers side, These truck seem to all have the same problem.
That's normal for your truck, the best thing you can do it what I did to mine cut off the water supply to the heater core, that will help a little. Best of luck to you.
Ethan Edwards I connected to a hot lead and found the correct one to the compressor side and it works I just ordered the Timp from Summit Racing to repair it correctly.
I have to also tell you that if you do what I did it will work for a little while but you system will over heat and the Freon will leak out, what happens if you are sitting too long the high pressure switch will not work so when I am sitting at a long light I turn off the toggle switch or my system will over heat and blow out the Freon, it works real good if you are on the freeway here is what your problem is I ordered mine on Amazon. www.ebay.com/itm/DODGE-RAM-1500-2006-TIPM-TOTALLY-INTEGRATED-POWER-MODULE-56049888-405/182458514830?hash=item2a7b5ffd8e:g:IAEAAOSwUmZahu7w
Great vid brada but plz replace HI n Low pressure sensors thats the mian problem on ram and anytime u low on freeon passangers side blowes warm and driver side cold i have 05 1500 hemi 👍🏻
@@leokarras6243 Mine blows warm out drivers side and cold out passenger side. I have replaced everything under the hood. I am not sure why it's doing it.
@@venomfastback have you installed a cut off valve on the heater hose like I showed in the video? The problem you're having is the blend doors in the heater box are bad, there is 2 ways to fix this one is to remove the heater box and replace the blend doors or the other way is it buy 2 cut off valves and install them on both heater hoses one on each hose that will fix the problem.
@@venomfastback I would put one on each hose after I posted this video I installed a second one and my a.c. did get a litter colder. It will also extend the life of your heater core.
In my 2006 ram 3500 my ac works but don’t blow cold. My compressor turns on but no cold air if anybody can help me out it would be greatly appreciated!
is your system full charged? you will have to check that first and if it is they you will have to do the same thing as I did and remove the dash out of the truck and then remove the AC box and replace the blend doors, That will be your problem or the other choice you will have is cut off the coolant supply to the heater core, install a cut off valve on both sides of the heater hoses, once you do that you will get cold air.
Its not allowing water to get to the heater core so how can it build up too much pressure you're wrong and it's been like that for more than two years and I haven't had a problem I'm a diesel mechanic and all semis do the same thing
@@leokarras6243 you need to use a ford ranger heater valve. instead of a dead head they create a flowing loop inside the engine bay which acts as a heat brake for the heater core.
I am not sure if you read all the reply's but if the compressor is not coming on the problem is the TIPM as I also just found that our a couple of weeks ago, I put a switch in my truck and problem solved, also I had to replace the fan clutch do to the fact that my ac system would over heat and blow the Freon out if the over ride if the truck was not moving and sitting in traffic, I also think you should install 2 cut off valves on the heater core that will also give you colder air, Good luck with your truck.
Leo Karras the dealer pulled the wires out down by the compressor when I had a winter oil change. So it was months before I noticed it. So last summer a guy change the clutch and spliced new wires in. Well the new clutch sometimes didn't lock up, and would start smoking. Last week it went out. The clutch fried. So I bought a new compressor and clutch this week and had it installed. Annnd nooooo power to the clutch now
I would replace the whole compressor but as for no power that is a big problem with these trucks a huge problem and it goes back to the early models usually it's the TIPM that goes out with these after going threw the whole system on my truck I went on a head and ordered one for my truck once it comes in I will replace it. in most cases once you connect and put a direct switch on the truck it will work until the system over heats then the Freon will leak out from the system overheating so if that happens you will have to change the TIPM the whole fuse box. the reason you will have to change it is do to the fact that the system in not communicating with the system and the fan does not know to come on when the system over heats, it will work when you are on the freeway or the truck keeps moving but if stopped in traffic or at a long light you will hear the sound of a large air leak then no more Freon and hot air. hope this helped you.
