hey guys been a while and i need some more help, today i noticed a good amount of tranny fluid under my truck after the morning commute, i de-greased, rinsed and inspected and it looks like its coming from the tranny cooler lines (the "isolater blocks" had moved allowing the hard lines to rub for who knows how long) i am ordering the "DieselManor Generation 2 Cooler Line for 1994-2002 Dodge RAM Cummins" with the port for trans temp guage but i cant find the rest of the lines on the web! any ideas? dont want to go to the dealership." also when i turn on my a/c i get a plesant aroma of anti freeze with the occasional puff of white smoke from the vents. heater core going bad? im assuming if it is the heater core its a royal pain in the a@$ thanks for any and all help guys

Have to change my ac condensor .some good ideas

My AC was out... I was assuming the evap core had cracked again. I took it by a new mechanic to check it out which he did while I waited... about an hour. He seems interest in discovering the problem & just fixing that, than replacing a bunch of parts. He discovered there was still some freon in it... he tried to get dye into it... I think he went back & forth 3 times... in the end he succeeded in recharging it. He thiinks that the filter was not replaced on the previous repair... perhaps it was plugged & he dislodged it. Anyrate I now have cold, although still stuck on the defrost mode (vacume control problem, that we knew). So the charges were $13 in freon, $135 in labor. The labor seems high for one hour but I don't know what AC service costs these days?

Ok Gang... I just got my replacement evaporator core from the local NAPA store. (Lifetime warranty - No cost) So when I go to pull the dash out I'm going to grab the video camera and record out the whole affair. Show you that pulling the dash is really easy on a Dodge Ram!

First off, I have no experience testing or troubleshooting automotive A/C systems, but I'm a quick study. Today is a sweetheart of a day -mid-60s, sunshine, and very light breezes - a perfect Spring day (finally). I'm cleaning up the cab of my truck, trying to get the smoke smell out of it left by the previous owner. I'm spraying the soft stuff with "frebreeze", and decided to spray some into the air intake for the HVAC system. Decided to check the A/C for operation - no dice. The compressor is cycling - runs for about 3 seconds then off for 10-15. Read up on the A/C system in the 2001 FSM (thanks again Mike). Last year I bought a set of A/C guages - haven't used them yet - perfect opportunity. I follow the gauge hook-up directions & get some readings. Static reading (engine not running) is ~60 psi. Started up the truck & put the control on Max A/C. Go around to the front & read the gauges. When compressor is running the suction side drops to about 15 psi when the low pressure switch opens up, then it resets at a ~ 40 psi. So the system is holding some pressure, the compressor is doing it's job, the pressure switch seems to be operating correctly, I presume it is just low on charge. Perhaps there is a slight leak somewhere, but not bad enough to tear it apart looking for the leak. I figure I should buy a can of 134A refrigerant & charge it up. This is the point where I need some guidance. All the bloody details; evacuating the hose that leads to the gauges from the refrigerant can? What side to charge-the low side or high side? How much, or when to stop - pressures or temps or both? Thanks in advance, Joe in St Louis

It's so cold in here my coffee gets cold before I can drink it. :lmao::lmao::lmao:

Have a 2001 2500 HD Diesel 5.9 Auto Tranny. I have a major A/C leak. Leaked down with in 4 months. Are there any common problems with the A/C's on this type vehicle? I am the original owner. I had freon put in in 2007 and 2009 and Nov 2010. Is there a likely area to look for the problem? Any help will be greatly appreciated.ThanksMohok

While changing the oil on my truck last night, I noticed that water was draining from the A/C hose from the firewall. I have not had the A/C on for the last month. I have the dash selector set to floor or floor/vent. With the engine running, I watched the A/C compressor cycle on and off. What would cause the A/C compressor to cycle on and off when the A/C is not selected? Sorry, posted this in the CR forum by mistake, so am posting it here now.

Will its started, I have just got the bumper off and I bet the truck raised 2 inches from just the weight . My question is can the evaporator or let me say can the A/C compressior stay hooked up while I pull eng. The reason is this A/C is the coldest A/C I have ever seen, it will get down to 29 degress in south Tx 100 plus heat, I just hate to break the seal .Has anybody ever done this?

Going to be vacuuming down my ac system soon ... And then recharge ... Any hints ?? Have the gear but not done before ,... ;)

Pulling my motor, need to unhook the condensor so that I can come straight forward with my motor, minus the oil pan. Can't lay the condensor to the side because the bottom line is hard all the way past the air filter box, can't bend that stuff... So it needs to come off and to get it off I need to evacuate the r134 charge without freezing my skin, frostbite, maming myself, and etc... Any good methods?

I am having a problem with my a/c compressor guys , On my way back from a trip my a/c when out and I check the fuse box because I noticed that the compressor wasn't engaging so sure thing the a/c clutch fuse was blown so I replaced it and it was back on and then about two hours later of driving the fuse when out again so any idea of what I should check for or fix? also I have been noticing that sometimes the carpet of the front passenger to be wet and just the place were you put your feet not the upper part and it doesn't smell like antifreeze I thought it was water from the rain but no its also there when it hasnt rain so any ideas on that ?Thanks !

Here are all of the components of the 2nd Gen A/C system, and what they all do. First is the compressor. The refrigerant is compressed making it even hotter, it becomes a high pressure high temperature vapor. http://www.mopar1973man.com//isx97/Truck%20Stuff/Ryan's%20Dodge/Under%20Hood/AC/IMG_1471.JPG After turning into a high pressure high temperature vapor, the refrigerant goes through the condenser. The condenser has ambient air running through it which cools off the superheated refrigerant, so much so that the refrigerant turns back into a liquid. Nevertheless, the refrigerant is still pretty hot and remains at high pressure. http://www.mopar1973man.com//isx97/Truck%20Stuff/Ryan's%20Dodge/Under%20Hood/AC/Condenser.jpg Now we make the refrigerant cold. To do this, it goes through an orifice tube. The orifice tube (not to be confused with an expansion chamber) has an orifice that holds back the pressure in the condenser and also allows the pressure to build, if there wasn't a restriction from the orifice, the condenser would quickly lose all of its high pressure and wouldn't do it's job. The orifice tube allows a metered amount of flow to go through it, and then expands into the hose that goes to the accumulator, becoming very cold. One side will be hot, the other will be cold. It will also now be low pressure. This can be seen with an air compressor when you blow air out of a hose. The air expands instantly and is cooled, that is why the air feels so cold coming out of that air hose. http://www.mopar1973man.com//isx97/Truck%20Stuff/Ryan's%20Dodge/Under%20Hood/AC/Expansion%20Valve.jpg It then proceeds into the Accumulator or Dryer. This stores the freon and also has things in it to help dry out the freon to prevent any moisture from building up. http://www.mopar1973man.com//isx97/Truck%20Stuff/Ryan's%20Dodge/Under%20Hood/AC/IMG_1470.JPG The last step is the Evaporator. This is inside the cab and air is blown through it, giving you cold air out of your vents. Technically speaking, it is absorbing heat into the refrigerant which then turns the liquid refrigerant back into a low pressure gas as it warms. They get stuff built up in them, as mine has. http://www.mopar1973man.com//isx97/Truck%20Stuff/Ryan's%20Dodge/Interior/Dash%20and%20Vacuum/IMG_1192.JPG So now that the refrigerant is a low pressure hot gas, it is sent back to the compressor to compress it into a high pressure, very hot, gas that has much more heat to be released in the condenser. If it was a low pressure gas, there wouldn't be enough volume through the condenser to keep you cool, it would also not be hot enough to release enough heat to keep you cool. So you compress it to make it really hot, the condenser has a ton of heat it easily expels, and the refrigerant expands back into a low pressure fluid that is very cold, and you have an efficient a/c system. Ambient temp influence the pressures of the high and low side.

HiBeen playing around with the airconditioning on my truck (as it blows hot air and has done ever since I got it -> but its not been warm enough for me to get on it).Figuring it was low R134a or whatever - got the walmart kit and started filling - problem was it would only allow like 10% of the can to be dumped into the low pressure port/accumulator before it was complaining of too highpressure on the guage. Well I couldn;'t hear the compressor - so after reading around I figured that was it.I climbed under and diconnected the sensor/wiring harness.I then tried to use a piece of wire to bridge the wiring harness - it smoked a little - then nothing.I got my multimeter out and it says no signal. (But I'm figuring there had to be a signal to cause the wire to smoke) ?? So - did I burn something ? More importantnly - have these 2 basic questions 1) How do I run a jumper wire (which I guess needs a 12V supply) to the sensor for the a/c compressor to get it to turn on ? Simply Using a paper clip etc on the sensor end won;t work as their is no power right ? Do I need just 1 wire from the +ve terminal of battery or do I need 2 wires (1 +ve and 1 -ve _ to complete the circuit ?? 2) How do I tell if the wiring harness is burnt or having an issue ? I stick my multimeter in the two connectors - but get 0 signal. Could it be a fuse - which fuse - in cab ? left side of truck where my edge juice is sitting on - or somewhere else in a relay ? Trying to work out if A/C compressor is dead or wiring harness is dead - or fuse - and how to force a 12V signal to the A/C clutch/drive compressor to get it to start circulating so I can fill up with the R134a refrigerant hope that makes sense gonna go get a pic now ......
